Integrated Fixed-Eye Cable Pulling Socks: The Solution

Published 26 Jul 2022

A custom solution for a global problem: how Slingco integrated fixed-eye cable pulling socks onto existing cables.

Cable Pulling Socks

Thorne & Derrick distribute a complete range of Cable Pulling Products to support the safe installation of LV, MV & HV cables into underground ducts, conduits and trenches. Cable socks and support grips are available for a wide range of applications such as the installation of 33kV & 66kV array cables prior to Jointing & Terminating in windfarm towers, turbines and offshore substations.

THE PROBLEM

Slingco teamed up with one of the world’s leading cable manufacturers to devise a way to integrate a fixed eye pulling loop on to cables manufactured for the global market. During initial consultations with the client, we identified several historical lead time and reliability issues experienced using their existing method and product.

THE SOLUTION

Slingco applied its proven New Product Development process (NPD) to create a solution that provided the client a superior solution. The key to the NPD process is our ability to listen to the client’s needs, understand the challenge and react promptly to provide a viable solution at a competitive price.

The Slingco team of cable management experts identified ways to create a more reliable and less expensive method to install their cables. With Slingco’s manufacturing and supply chain expertise, we were able to shorten the customer’s lead times and stock out issues.

Fixed eye crimp-on cable socks are easy to install, minimise the length of cable being impacted by the pulling device and are a secure way to pull and manage the cable during the manufacturing and spooling process.

Crimping the pulling eye onto the cable is quick and easy using a Slingco hydraulic crimper, which securely holds the cable during all pulling and cable management processes.

Slingco were able to demonstrate an effective design, manufacture and standardise the product used today, and able to provide an impeccable service via a robust manufacturing supply chain. Our ongoing quality assurance processes ensure the continuous reliability of the product delivered.

Main Improvements:

  1. Material specification analysed to reduce fatigue / cracking.
  2. Colour coding for easy identification. Not just pulling eyes but tooling as well to ensure the correct tool is used.
  3. New tooling and standardised swage diameters introduced to prevent over crimping. Reduce the number of sharp burrs.
  4. Improved marking of product for easy-to-read identification purposes and easy positioning of the product for swaging.
  5. Box weights and quantity batch size introduced for ease of lifting and movement.
  6. Acceptable minimum order quantities and reorder levels introduced.
  7. Ongoing testing support for new cable designs introduced by client to check compatibility of Slingco fittings.
