Thorne & Derrick, distributors of a range of Cable Pulling & Laying equipment, are pleased to announce that Slingco’s innovative Catchblock has received formal approval from Network Rail and National Highways (formerly Highways England).

In addition, National Grid has now endorsed the use of the Slingco Catchblock system.

Catchblock

OHL catenary roller system

Catchblock from Slingco is a system for replacing and recovering overhead conductor cable and makes some pretty big claims, including reducing disruption, risks of accidents and costs during replacement of conductor cable.

Nick Dykins, Managing Director, reported: “Our single system has been fully and permanently approved by Network Rail and National Highways.”

“In addition, Network Rail has approved temporary certification for our Catchblock twin system for 12 months. For our utilities contractors this means the seamless replacement of cable with minimal disruption to infrastructure.”

Catchblock is now supplied in two versions – UK and export to meet growing national and international demand for this product.

Catchblock from Slingco is approved by Network Rail and National Highways for OHL Conductor replacement.

Lightweight, robust and easy to deploy, CatchBlock helps to increase efficiency and reduce costs.

REDUCED DISRUPTION
CatchBlock is an innovative OHL catenary roller system. Designed to deploy a twin-rope system, it allows the recovery and redeployment of broken conductors without the need to take possession of road/rail or client/third party property or infrastructure.

REDUCED ACCIDENT RISK
CatchBlock significantly reduces the need for erection and dismantling of scaffolding – cutting down the risk of accidents and harm to site workers.

REDUCED STRINGING COSTS
The reduced need for scaffolding, ease of deployment, and the ability to recover and redeploy, results in a faster, more efficient operation. With fewer hours of effort and less equipment required, Catch Block can deliver substantially reduced costs.

TRUSTED INNOVATION, OUTSTANDING SUPPORT, BESPOKE SOFTWARE
In addition to our complete engineering support service, we offer bespoke software for the CatchBlock system to replace spreadsheet calculations. Intuitive and easy to use, this software needs only limited training to enable site staff to complete regulatory checks. The CatchBlock system has been rigorously trialled and tested.

At no point has there been the need to take out possession orders for property or infrastructure, even with a failed conductor.

CatchBlock has received formal approval from Network Rail and National Highways

Cembre | New Generation “Bilinear” Cordless Crimping Tools Available From Thorne & Derrick

Cembre “Bilinear” Cordless Battery Crimping Tools

CEMBRE Bilinear Cordless Crimping Tools

ND Series, Battery Crimping Tools 18.0V – 2.0 Ah

Cembre have launched a new generation of hand-held cordless battery crimping tools, characterised by a “Bilinear” mechanical design. Operator comfort and convenience are key factors in producing repeatedly consistent high integrity crimped joints.

Thorne & Derrick supply the Cembre ‘ND Series’ of bilinear tools. They have their mechanical centre of gravity nearest to the operator’s wrist to optimise the overall ergonomics of the tool and provide a wider support for the hand.

Thus the innovative misalignment between the pump drive mechanism and the hydraulic system both reduce the torque generated on the operator’s wrist and best distribute the stresses acting on the hand.

➡ Cembre offer a complete range of battery operated cable crimping tools for use with crimps, connectors and lugs up to 400sqmm including medium/high voltage cables at 11kV/33kV.

“Bilinear” Cordless Crimping Tools Features

Smart Release System

“Smart Release Technology” is a new development by Cembre whereby an intelligent oil pressure release system stops the motor at the end of the crimping cycle.  Automatic retraction of the ram only occurs when the operator releases the start button, this allows visual verification of the jaws to ensure that they have fully met prior to releasing.

Similar tools with ‘standard’ automatic return do not permit this visual verification that full compression has taken place before releasing pressure.

Electronic Pressure Sensor (EPS)

The Electronic Pressure Sensor (EPS) guarantees the precision of the crimping operation, checking the actual value of pressure and informing the operator about possible errors.

Smart Tool Technology

Data recording and intelligent control allow complete verification of operational parameters. SMARTOOL technology enables the user to to store data from up to 200,000 cycles on the integrated memory card for transfer to a computer via a USB cable.

New two-speed hydraulic system

On the new generation of tools, a dual speed hydraulic system has been implemented with the double concentric pumping system and interlocked spring, the original patented solution by Cembre.

Faster compression and greater crimping force result from the new two-speed hydraulic system: a high approach speed which automatically switches to a low crimping speed, ensuring optimal use of the available energy.

New Multifunction OLED Display With Touch Button

Equipped with Li-Ion 18 V-2Ah rechargeable high capacity batteries. Fitted with a maximum pressure sensor for enhanced precision and repeatability of the maximum pressure cycle, and a pressure relief valve providing additional safety for the operator.  Weight and balance have been reconfigured to yield improvements in handling and convenience.

The more rigid structure of the bi-component plastic body provides greater mechanical protection while its  rubber inserts boost operator safety and comfort.  Quieter operation, illumination of the working area via LED lights and a minimum of vibration enhance the tool’s practicality.

Are All Types Of Cable Terminations The Same?

Cable Terminations

3M Cold Shrink

Guest Article by 3M Electrical

From lost time to repairs, cable failure can result in costly power outages. Often, these failures are the result of electrical stress.

Improper cable termination stress control can result in premature electrical aging and can lead to failures. It can also present risk to the overall safety and reliability of a utility distribution system, windfarm, or heavy industrial facility.

The question is are all cold shrink terminations equal? Not necessarily. Test results indicate this is not the case, taking stress control into consideration. Learn more about Geometric and High-K stress relief, the differences between them, and how test results show better performance with 3M’s method of using High-K stress relief.

Managing electrical stress comes down to design.

I’ve noticed when meeting with customers that there is a consensus that all types of cable terminations are equal. That’s simply not the case. Just because cable termination accessories may look similar, it doesn’t mean they perform the same.

To help dispel this myth, we ran our own study comparing our own 3M™ Cold Shrink Termination technology, which leverages capacitive stress control versus geometric stress cones. Here’s what we found.

Capacitive stress control vs. geometric stress cone: what’s the difference?

A test was conducted in a controlled laboratory environment to determine which method is most effective at controlling electrical stress. As part of our study, we looked at the performance difference between two common types of cable terminations:

1. Geometric Stress Cone: This is an electrical stress control method aimed at reducing stress at the shield discontinuity. It works by extending the shield and gradually increasing the thickness of insulation under it.2. Capacitive Stress Control: This is a high dielectric constant (Hi-K) stress control method that controls the stress at the end of the insulation shield. It lowers the electrical stress at the point of shield discontinuity by diverting the electrical stress along the cable insulation interface.

The comparison: 3M™ Cold Shrink Products that use Hi-K capacitive stress control versus competitive cold shrink products that use geometric stress control.

For the interfaces’ stress control method, we chose our own 3M™ Cold Shrink QT-III Termination. It’s designed to spread the electrical stress lines, which helps to reduce the surface stress, resulting in improved termination performance and overall cable life expectancy.*

After putting both methods through several tests in the 3M lab, the results yielded three key benefits.

Performance Testing of Cable Terminations

Performance results

capacitive stress control vs. geometric stress cone study.

Our test results showed that the design behind cable termination accessories can have an impact on electrical stress management and can help prevent premature electrical aging, failures, and power outages.

There are three crucial benefits of choosing 3M™ Cold Shrink QT-III Termination:

1. Reliability: The Hi-K stress control helps to prevent leakage and electrical discharge for higher cable reliability.*
2. Uniformity: The design allows for a uniform distribution of the electric field, helping lower surface stress and improve track resistance (i.e. friction).*
3. Safety: 3M™ Cold Shrink QT-III Termination is easy to install and requires no additional jointing tools, it helps improve overall safety by helping lower the risk of cable preparation mistakes associated with longer insulation interfaces.*

Overall, test results showed that 3M™ Cold Shrink Termination technology has a excellent behaviour compared to the competitive stress cone technology.*
