In this Article we cover the following:

• W-crimp and indent crimp for different cross-sections
• The permitted cable spectrum for indent crimping comprises both Class 2 multistranded copper conductors, as well as Class 5 and Class 6 fine and ultrafine-stranded types in accordance with VDE0295 up to a cross-section of 400sqmm
• Klauke F cable lugs for ultrafine and fine-stranded conductors avoid fraying
• Practical crimping method for small cross sections below 6sqmm and also in switch cabinet construction up to 1000V

Indent crimping

Well-tried yet reliable?

Benefits & Limitations: the oldest form of electrical connection, indent crimping has proven its worth in countless electrical cable termination applications. Yet for some time now, experts have been repeatedly asking the question: is indent crimping reliable?

Why this uncertainty?

Today, hexagonal crimping is considered to be the technical standard that has generally become established. But indent crimping is considered to be an acceptable and a reliable form of cable crimping that is preferred for switch cabinets of up to 1000V.

Indent crimping is still a reliable form of crimping cables, often used in the construction of switch cabinets up to 1000V.

Indent crimping is a purely manufacturer specific type of crimping.

In other words – the manufacturer must ensure that a standardised cable crimp can be produced using its components. Leading manufacturers demonstrate this through appropriate tests.

In tests to IEC 61238, for example, Klauke proved its crimping tools and cable lugs combined can be used to make connections of equivalent quality to a hexagonal crimp.

Warning: unlike hexagonal crimping, indent crimping is suitable only for processing copper. In terms of technology, indent crimping is set apart by its high degree of compaction.

The greater impact forces, however, cause high material stress. So it‘s important to remember that connections caused by indent crimping are always strain relieved.

Indent crimping allows multistranded, fine-stranded and ultrafine-stranded conductors to be permanently connected

The variants are W-crimp and indent crimp. There are two different versions of indent crimping in use:

• the W-crimp for cross-sections from 0.5sqmm to 16sqmm
• the indent crimp for cross-sections from 6sqmm to 400sqmm

Types Of Indent Crimp

The W-crimp is ideal for smaller cross- sections, since the material in the region of the two tips of the crimp insert is extremely highly compacted

Indent crimping is especially suitable for cross-sections from 6sqmm to 400sqmm

The W-crimp is preferred for smaller cross sections, since the material in the region of the two tips of the crimp insert is extremely highly compacted. Indent crimping is commonplace and generally accepted for processing small cross-sections, since the hexagon crimp is normally used only from cross-sections upwards of 6sqmm.

For multi-stranded, fine-stranded and ultrafinestranded copper conductors

The permitted cable spectrum for indent crimping comprises both Class 2 multistranded copper conductors, as well as Class 5 and Class 6 fine and ultrafine-stranded types in accordance with VDE0295 up to a cross section of 400sqmm.

Class 1 round single-stranded (rs) conductor (commonly known as solid conductor. Class 2 round multi-stranded (rm) conductor. Class 5 fine-stranded conductor 5 (commonly known as flexible conductor. Class 6 ultrafine-stranded conductor 6 (commonly known as highly-flexible conductor).

Conductor Types

In contrast to the hexagon crimp, thinned conductors can also be reliably crimped without transmission losses by means of indent crimping. The reason – thinned cables have in reality a smaller cross-section than is nominally specified – a specified cross-section of 50sqmm can in actual fact only be around 43smm, for example.

Thinned lines are produced from high-purity copper. Despite its smaller cross-section, this material has identical conductivity characteristics. The benefit to the manufacturer is the reduced material usage and the associated lower costs.

One of the key advantages of indent crimping is this versatility in the wide range of the conductor types to be processed. What’s more, all these conductor types can be indented simply and cost effectively using one tool. Klauke offers a mechanical crimping tool for indent crimp that covers a cross section range of 185sqmm to 400sqmm, for example.

The Klauke mechanical crimping tool K07 for indent crimps covers a crosssection from 185sqmm to 400sqmm

Generally speaking, only mechanical hand crimping pliers are used for indent crimping.

The cable crimping profiles to be used are based on the tube dimensions of cable lug and connector. But because indent crimping is not a standardised form of cable crimping, it is crucial that high-quality materials and crimping tools tested to IEC61238 from the same manufacturer are used.

A professional indent is obtained only from clean workmanship using a suitable tool and matching cable lug. That means the crimping tool must be correctly applied and the indent made up to the end stop of the tool. The same number of indents as for a hexagonal crimp is required. For example, a professional hexagonal crimp of a tubular cable lug with a cross-section of 240sqmm calls for four narrow crimps; an indent likewise requires four crimps.

Just like a hexagonal crimp, the indent crimp for a cable lug with 240sqmm cross section also requires four narrow crimps

With indent crimping too, the cross-section is stamped on the back of the cable crimp for checking. Important in all cases – to avoid under or over-crimping the use of a suitable and well-maintained crimping tool is a basic pre-requisite.

Incorrectly made cable crimps due to an incorrect tool setting for example can increase contact resistance which can in turn cause temperature rises and ultimately cable fires.

Indents made incorrectly due to unsuitable crimping tools, for example, can in the worst case cause a cable fire

Klauke recommends that its cable lugs are crimped using only Klauke tools – this is the only way the electrical engineer or cable jointer is guaranteed the use of matched cable lugs or connectors and tools, which are the prerequisite for a reliable connection.

Also important in this regard Klauke F or R cable lugs (Cu copper standard version) can be used for indent crimping.

F and R-series cable lugs can be used for indent crimping

Klauke F & r series cable lugs

Due to their design F cable lugs for fine stranded and ultrafine-stranded conductors avoid the problem of fraying as they are introduced into the cable lug. These tubular cable lugs have a larger internal tube diameter than standard cable lugs – they also have funnel-shaped widening to better guarantee cable entry into the lug.

F cable lugs have a larger tubular inside diameter than standard cable lugs; they also have a funnel shaped widening

Besides easier handling, this also provides advantages in terms of safety – cross-section tapering due to fraying is prevented and so the cable retains its full cross section.

The funnel-shaped widening of the F cable lugs prevents a cross-sectional tapering of the cable caused by fraying

Suitable for use with Klauke F series tubular cable lugs, various manufacturers also offer joints for conductor extensions or repair purposes. These also have funnel-shaped widening and an enlarged tube diameter. A central impression prevents the two cable ends being inserted unevenly.

Tubular Cable Lug – Commercially Available

In addition to DIN cable lugs, various manufacturers offer standard Klauke R-series tubular cable lugs. Due to their dimensions, these tubular cable lugs differ from DIN cable lugs – they are usually shorter than the DIN designs. But because they are governed by the same test standard this does not affect the durability of the electrical and mechanical connection.

The standard R series tubular cable lugs, which are shorter than DIN cable lugs, guarantee a durable connection when indent crimping is carried out correctly

Conclusion & outlook

Indent crimping remains a standardised and practical crimping method. For small cross sections below 6sqmm in any case and also in switch cabinet construction up to 1000V. If the recommendations given in this article are followed, any uncertainties about their reliability are unfounded.

There is no doubt, however, that the acceptance of indent crimping among experts is not quite what it once was with hexagonal crimping increasingly preferred and specified. It is therefore important to clarify with customers in advance as to whether they allow indent crimping in their technical facilities and plants. The arbor and 4-arbor crimp offer a similar degree of compaction to indent crimping.

These cable crimps even allow the production of gas-tight crimped connections. We will be explaining what is important to note about these types of crimp in a later issue.

Cutting SWA Cables – Recommended Cable Cutting Tool For Steel Wire Armoured Cables

LV-HV Cable Cutting Tools For Copper, Aluminium & Telecommunication Cables

• uploaded by Chris Dodds - Thorne & Derrick Sales & Marketing Manager

This Post addresses a customer query received earlier today by Thorne & Derrick, the stockist and supplier of Cembre, and highlights suitable cutting tools for use with SWA Armoured Cables.

Question About Cutting SWA Cables

Is the Cembre B-TC950E capable of cutting a Steel Wire Armoured cable?

The cable has a outside diameter of approximately 70mm. The cable has 3 triangular (sector) aluminium cores, the cores cross sectional area is unknown but it is suggested that they would be approximately 240sqmm. If the Cembre B-TC950E cable cutter is suitable could you advise of the approximate number of cuts that the blades could do on this cable before needing replacing. Or would you recommend an alternative cable cutting tool?

The SWA (steel wire armour) wraps completely around the outside of the cable under the outer layer of PVC – each steel wire in the armouring is approximately 3mm in diameter.

We require 5 cable tools.

Cembre reply:

Cembre B-TC950E is capable of cutting up to 240sqmm 3 core SWA cable (with 2 cuts at 90 degree angles) – this includes LV MV HV cables up to 11kV/33kV.

Hydraulic type cable cutting tools are also available.

With regards to an approximate number of cable cuts before the tool blades need replacing, we would not be able to provide this information as there are too many variable and external factors involved to give a definite answer.

We can quote for spare cable cutting blades as applicable for use with all Cembre manufactured tools.

Should you also need to terminate the same specification cable using cable lugs we would recommend the Cembre HT131-C tool which is a hydraulic crimping tool for use up to 400sqmm using hexagonal die sets.

When it comes to cutting and crimping cables the trusted world-market leading manufacturer of cable tools is Cembre.

The quality of the soldered joint is key to the crimp result.

Poor-quality soldered joints carry the risk of opening during the crimping process.

Unlike the compression cable lug to DIN 46235, solderless terminals are not processed by hexagonal crimping, but instead by indent crimping.

In this Article we cover the advantages of using Electromechanical Crimping Tools:

• With a manual force of up to 20 kilograms per crimp, excessive strain in the wrist and forearm can occur over time when cable crimping
• There is a good case here for taking measures to safeguard against such conditions and prevent expensive employee absences and injury
• Electromechanical cable crimping tools reduce the physical effort, achieve the best crimping results and also guarantee the consistently high quality
• For specialist operations in which large numbers of crimped connections have to be processed quickly, purchasing such crimping tools is justified
• DIN 46234 standard compliance and cable lug connector installation

Cable Crimping & Health & Safety

It usually begins innocuously: first a numb feeling in the thumbs, index and middle fingers during the night. But then later, pain and sensory disorders throughout the day too. The hand becomes less sensitive, the fine motor skills start to dwindle and the hand gets weaker.

Day-to-day tasks become increasingly difficult and certain professional activities are difficult or even impossible to accomplish. This is caused by what is known as carpal tunnel syndrome. A nerve in the hand is permanently trapped against a constricted area that is inflamed – here are the typical signs and symptoms:

Carpal Tunnel Syndrome – Cable Crimping

One suspected cause of this widespread condition is one-sided strain, which is often encountered in the electrical trade for example. There is a good case here for taking measures to guard against such conditions and prevent expensive employee absences.

Choosing the correct electromechanical crimping tools can help reduce workplace injuries and improve site and worker Health & Safety.

One of the most commonly recurring tasks in switch cabinet construction and installing LV cable joints is the crimping of cables. This task is usually carried out using mechanical type, ratchet crimping tools and in most cases, is completed without any problem at all. It can be become critical, however, when it has to be carried out by employees on a recurring basis. With a manual force of up to 20 kilograms per crimp, excessive strain in the wrist and forearm can occur over time.

Employee Health & Safety – less physical effort with electrically-driven cable crimping tools

One key factor is considered to be the number of cable crimp operations that are carried out on a regular basis. While a young and healthy employee who has not previously experienced excessive strain can easily achieve 100 to 150 crimps per day without their health being adversely affected, the use of a cable crimping tool with motorised drive is recommended for higher numbers of repetitive crimps.

Leading manufacturers now recommend tools that allow work to be carried out much more comfortably with far less physical strain.

The electromechanical crimping tool Klauke Micro with 10.8 V lithium-ion battery, for example, requires a manual force of just two kilograms per crimp.

In other words: the force that needs to be delivered from the hand and forearm is around 90% less than that required for a crimping tool operated purely by hand.

“When we developed our Electromechanical Micro, the aim was to manufacture a cable crimping tool that is easy to use and would allow ergonomic and health-promoting work, thereby combining the benefits of a manual crimping tool with the ease of a cordless one in a single cable tool device”, explains Lutz Remmel, Product Manager at Klauke.

To make the day-to-day tasks of a qualified electrician easier and benefit from the time-saving, the selected crimping tool should cover the broadest range of tasks possible.

The electromechanical tool from Klauke is able to process cable cross-sections from 0.14 to 50sqmm with a cable crimping force of up to 15KN, with a long-term time saving compared to the mechanical crimping tool.

Because, in terms of the system concept, the electromechanical crimper tool is designed to take the interchangeable die sets from Klauke’s 50 series, it is also suitable for crimping various cable types, cable end-sleeves, and also tubular cable lugs, insulated solderless terminals and pin cable lugs.

This not only makes the cable tool a versatile companion for switch cabinet construction, it is also gentle on the installer physicals joints and allows consistently fast operations for numerous other manual, industrial and high voltage cable crimping applications.

The sequence is always the same: first, the manual pre-clamping. When the operating lever is actuated, the crimping jaws of the tool close in order to fix the electrical cable connectors.

During this particular step, the cable lug or connector material can be precisely aligned and positioned. In the second step, the cable crimp is achieved by the force of the motor.

The operating lever simply needs to be depressed fully and the crimping tool automatically starts the crimp process, which takes no more than 1.5 seconds, depending on the material.

Once the cable crimp has been made, the operating lever is released to initiate the return movement, also fully-automatic, into the original position.

Electromechanical Crimping Tool Operation

Electromechanical crimping tools reduce the physical effort, and offer the following advantages: they achieve the best crimping results for minimum force, they also guarantee the consistently high quality of these electrical connection results for years afterwards.

This is because a suitable cable crimping tool in faultless condition (properly maintained) is crucial to avoiding under-crimps and over-crimps. Otherwise, the consequences can be hazardous: incorrectly-made crimps can, for example, increase joint resistance which can in turn cause temperature rises and ultimately trigger cable fires.

When choosing a crimping tool, simple and reliable operability is the key to ensuring safety.

Cable Tools & Costs v Benefits

When Is Investment Returned?

Profitability, of course, is the question posed by any investment. The cost of a branded electromechanical crimping tool is around 180 Euro (?), or more for a manual crimping tool.

Any concerns about the durability and reliability of the electrical variant of crimping tools are unfounded. For its Micro model, for example, Klauke states a long service life if the service intervals are maintained (at 35,000 press or crimp cycles).

The cable crimping tool is equipped with a multi-function LED for maintenance display and data transfer, which can also be used to transfer crimp and tool data to a PC via a USB adapter from the tool accessories range. Test reports showing date and time can readily be created as a PDF for recording completed crimp operations. An effective way of demonstrating a safe and correct working method.

Purely mechanical manual crimping tools do not offer this option of displaying wear and creating documentation.

And also the lithium-ion batteries now used in most cable crimping tools give no cause for technical concern. These energy sources conform to a perfected technical standard that applies today in practically all sectors in which rechargeable batteries are used. Lithium-ion batteries are set apart by short charging times without memory effect and a constant, uniform power output.

DIN 46234

The charging time for the battery installed in the Klauke tool is around 40 minutes. A fully-charged battery, can then achieve some 300 crimps on copper cables with a cross-section of 10sqmm in accordance with DIN 46234. Despite this high efficiency, the total weight of the tool, including the battery, is just 960 grammes.

• DIN 46234 Standard – Terminal Ends For Solderless Connections, Ring Type, Without Insulating Sleeve (Copper Conductors)

Yet a far more important factor for assessing profitability, is sustaining the employee’s physical strength. The cost of sick leave due to carpal tunnel syndrome, which is mentioned at the beginning, tendinitis or tennis elbow, far outweigh those of procuring electromechanical crimping tools in the short-term.

Electromechanical crimping tools are preferred by panel builders for carrying out the termination and connection of LV MV HV cable conductors into electrical control panels.

Conclusion

Electromechanical Crimping Tools

The decision to invest in an electromechanical crimping tool should be made according to economic calculations. For specialist operations in which large numbers of electrical cable connections or cable lugs have to be processed quickly, purchasing such cable tools makes is clear sense.

Electromechanical crimping tools not only increase the efficiency of work processes but also protect the health of employees. Since maintaining good health also means sustaining physical strength, such an added investment can benefit employer and employee in equal measures. Especially in light of demographic change and the shortage of specialists this brings about, physical fitness has become an economically valuable asset which must be sustained for as long as possible.
