Flexible Cable Joints

The port authority and container handling industry is a key component in the backbone of the British economy. Directly employing 117,200 workers, contributing £7.9 Billion to the UK economy and providing £2 Billion in taxes as reported by Oxford Economics.

It is therefore essential that the industry runs in an efficient and seamless manner.

The uninterrupted supply of electrical power as well as and the redevelopment and expansion of ports around the UK means there are many kilometers of LV cable being used within the shipping industry.

Conductix-Wampfler Flexible Cables – Maintaining Their Flexibility With 3M M20, M30 And M40 Cable Joints

Cables

Conductix-Wampfler are manufacturers of flexible LV cables used within the port authority and container handling industry. Cables are typically stored on large cable reels meaning they must be intrinsically flexible. This allows the cable to be reeled around a drum and re-coiled when required.

The cables have a multitude of special features, all of which enable the cables to be used effectively and efficiently within the industry. These features include:

  • An outer sheath with extreme resistance to aggressive environments
  • Very high resilience due to a very short lay stranding
  • High axial rigidity thanks to interlinked inner and outer sheaths
  • Great resistance to corkscrew due to reverse twist stranding
  • Stable construction and geometry based on extruded fillers

When multiple lengths of cable are being jointed together, it is imperative that their flexibility and bend radius is not compromised by the cable joints being used. The 3M Scotchcast M Series of cable joints and repair kits are a flexible, cold pour resin system designed for the permanent jointing and repair of flexible cables – this includes single and multi-core LV power cables.

Jointing Cables

Once installed, the 3M Electrical flexible cable joint using Scotchcast resin provides a waterproof seal that will not be compromised during cable installation. The flexiblity of the 3M Scotchcast M20, M30 and M40 range is such that they will remain intact and continue to perform during frequent coiling of the cables and direct burial or submerging of the joint.
