Indent Crimping Of Cables – Benefits & Limitations
uploaded by Chris Dodds - Thorne & Derrick Sales & Marketing Manager
Thorne & Derrick International, based in the UK, are leading suppliers of cable crimp lugs and associated crimping tools for Low, Medium & High Voltage Cables and Power Systems – this series of articles by Klauke discusses the theory and practise of installing compression type cable lugs and connectors for use with copper and aluminium conductors.
Klauke cable lugs and crimping tools are used by Jointers, Linesmen, Panel Builders and Electrical Engineers to install underground cables and overhead line conductors on power, transmission and distribution networks including LV MV & HV systems, 11kV-33kV.

In this Article we cover the following:
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 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
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
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.

Today, Thorne & Derrick welcomed Jason Leatherland (UK Manager at Aplicaciones Tecnológicas (AT3W) Lightning Protection & Earthing) to their UK office to learn more about their innovative Exothermic Welding System – Apliweld Secure+ is the safest + most efficient system for establishing Exothermically Welded Connections on substation earthing projects in the UK DNO, Power Transmission & Distribution and ICP sectors.
So What’s New?
The market-leading modern technology with remote electronic activation using Bluetooth replaces the conventional exothermic welding system dependent upon a manually applied spark using a Flint Gun for the welding and bonding connection of copper conductors including copper earth rods, cables and earth tapes.
Apliweld Secure+ replaces traditional welding powders (and all of their size variations) with a welding tablet compound activated remotely, by up to a safe 5 metre distance, from the controlled explosion location – the electronic starter reduces risk of burns injuries and improves operational Health & Safety.
Apliweld Secure+ is accepted or in the approval process for use at National Grid, Northern Powergrid, Western Power Distribution, Scottish Power Energy Networks (SPEN) and Electricity North West (ENWL).
AT3W are a Spanish manufacturer and supplier of Earthing & Lightning Protection products and solutions – their unique selling point is their dedication to innovation and R&D within the industry along with their complete product/solution portfolio.
What is Exothermic Welding?
Apliweld exothermic welding is a process that achieves the molecular bonding among two or more metallic conductors by a chemical reaction. This molecular bonding improves mechanical, electrical and anti-corrosion properties compared with any mechanical or clamped connection. Apliweld exothermic welding is the most efficient method to achieve permanent, reliable and high conductivity connections for any LV MV HV substation or installation requiring an earthing system.

Contacts us NOW to arrange a DEMO or to discuss your Exothermic Welding requirements
Traditionally, exothermic welding required the user to be provided with multiple cartridges with different welding powder weights for establishing various connections.
Once the conductors were inserted in the graphite mould the welding compound and the reactive powder (usually a flammable compound) were poured into the crucible. Then a flint gun applied manually to the starting powder at arm’s length produced a spark triggering the exothermic reaction.
Apliweld Secure+ utilises exothermic welding tablets NOT powders which are activated at safe working distance to suit all conductor combinations and configurations. The exothermically welded earthing connections are engineered to provide a permanent, molecular bond that will resist corrosion and loosening.
Thorne & Derrick will be working with AT3W to introduce and develop specifications and business for the Apliweld Secure+ exothermic welding system.
Jason Leatherland comments, “having worked successfully together with Thorne & Derrick in the past, I was keen to demonstrate and discuss this product system with them as I knew they would be best suited to showcase the system, and in particular, its increased health and safety benefits, to the most relevant sectors in order to increase the users efficiency and reduce the potential of site accidents from exothermic welding.”
Jonny Hewitt (T&D UK Power Team) added, “working with the UK DNO’s and their preferred ICP’s we look forward to further developing relationships and presenting the exothermic welding system to existing and new clients. We will be working closely with AT3W to introduce the product to market and improve worker and site safety in the utility industry.”

World-Class Cable Splicing Training
Training for Today to Meet Tomorrow’s Challenges
The following sequence of photographs provide a behind the scenes glimpse of Splicer Training at the Quanta Services Lazy Q Ranch, a state-of-the-art facility where the Art & Craft of Cable Splicing is alive and kicking. Nestled in the small town of La Grange where the Colorado River rolls and the Texan rattler hisses, the next generation of Cable Splicers are forged in the fires of their scorching hot pots of lead.
At the 2,200-acre campus Quanta employees receive hands-on instruction from passionate Master Trainers in a controlled environment focusing on safety, skill development and certifications. Quanta has even partnered with a local university to create a curriculum specific to their industry.
Workmanship Rules OK!
Quanta do not set the standards – they raise the standards and lift the bar higher and then higher. There is no wriggle-room for the slightest splice error or even the most minor of measurement misdemeanour. Excellence is expected and why not?
James and the Lazy Q crew are changing the industry.
All practice splices and test splices are completely dissected as part of the curriculum – the test splices are actually cut into up to 10 or more pieces. The Splicer Assessor forensically checks the students submission – analysing tape application, scrutinizing measurements, checking connector and studying the lead seal and end wipes of the lead sleeve.
All images of cable splices and workmanship in this article were built by students.
RIP PILC?
Traditional cable Splicing skills are not dead or even dying out. PERIOD.
At least not Stateside.
Out on the range at Lazy Q, trainees are perfecting soldering, wiping and the complex intricacies of PILC Cable Splicing. Despite the 21st Century fashion for the grid to “Go Unleaded” as modern medium voltage power networks adopt polymeric cables there remains a demand for PILC Splicers with competent taping, soldering, wiping and compound pouring skills.
Yes, the prolific rise of Cold Shrink Splices has necessitated Jointer Training Centres to keep pace with cable manufacturing technology and introduce modules to cover the requirement to joint, splice and terminate MV cables using cold shrink as well as heat shrink accessories.
However, like it or not, with documented service lives of 60-80 years, PILC is here to stay.
Student Splicers – here the trainees are cleaning down their lead pots in preparation for the 1/c 250 MCM lead splice. Using specialised cable splicing tools including soldering irons, melting pots, pouring ladles, tallow wiping cloths, lead ringers, compound kettles, stearine candles and paraffin dippers to perfect the wipe.
Pencilling Preparation – a student performs the cable pencilling in preparation for the 3 conductor sweat onto the practice cable splice. Safe knifework requires a steady hand, cool concentration and the manual dexterity of a surgeon. Because the power they’re supplying is electrifying and the Splicer must not lose control.
First, build the splice. Second, break the splice. Third, make the “Y” into a “V”.
With the insulators in place, the “Y” is now a “V”.

Practice Makes Perfect – a practice cable splice by one of the student Splicers that was done in preparation of the test splice – 3/c 500 MCM PILC cable splice. Splice integrity is crucial – localised lead corrosion permitting moisture ingress into cable insulation through cracks in the wipe area being a main precipitation of cable failure.
Student practicing cable preparation and set up for sweating the connector.
PILC Splicing – here the student is pre-taping to fill in the insulation layer across the core connector.
Lead Splicers Night Light – a hot pot of lead that is being cleaned with Stearine. Stearine is a product used to cool the lead and to help remove impurities.
Quanta Services has the knowledge and expertise to handle a full spectrum of MV HV Power projects. From the most straightforward, single-component installation to the most complex, multi-state project, Quanta can handle the job safely, efficiently and cost-effectively.
For Quanta, safety is the core that all their values centre around. Quanta will find a solution for every customer, but they will also find the option that protects their people, their customers and their communities.
Safety – Core Principal of Quanta Services
John Colson, founder of Quanta Services opened a training facility known as Lazy Q Ranch in August 2015 where the industry workforce could be trained under the strictest safety measures.
The Lazy Q Ranch is a world class training facility situated on over 2,100 acres focusing on safety education, skill development and certifications.
Training is available for electric power lineman on cutting-edge technology for all transmission structure types and up to 345kV. This area is powered by its own substation, completely separate from the power provided for the Ranch. Quanta Energized Services oversees this portion of the training facility, bringing proprietary technology techniques to the workforce.
The oil and gas section houses pipelines in all major diameters, a flow loop and underground testing capabilities. The pipeline area was designed to be flexible and allow for various diameter pipes to be brought in for integrity testing and training, making this a custom-solution for training on a challenging project.
The telecommunications village features a small town with homes at various stages of construction. This enables development training at all milestones of a project.
The Lazy Q Ranch evolves with the industry and was designed to mirror Quanta’s growth. As Quanta Services expand their service capabilities, so will the training facility.
Currently Quanta are offering the following training courses:
