CTL Components has introduced a medium-voltage cable jointing kit that uses a combination of heatshrink technology and two-part polyurethane resin to provide complete protection against the ingress of moisture even in locations with a high water table.

Known as heatshrink+resin, the new kit includes heatshrink tubing for insulating core conductors and also features a sealed two-part resin system that provides a clean, convenient and reliable method for mixing the resin compound.

Pre-determined quantities of resin and hardener are supplied in hermetically sealed plastic pouches, and mixing is carried out without any risk of skin contact.

In addition the kit contains a clear outer shell for easy inspection of the joint, a choice of shear-bolt or compression ferrules for the core connections, and earth continuity components such as constant-force springs and a strong aluminium wraparound cage with rubber spacers to ensure correct positioning. All components are supplied in a single sturdy box for ease of use in the field.

Ideal for cable jointing applications in the electricity supply industry, the heatshrink+resin kit complies with the requirements of the Din VDE 0278 Pt 629-1 and Cenelec HD 629.ISI standards. Six versions of the kit are available, covering polymeric, paper or transition joints for three-core cable sizes ranging from 35 to 300 sq mm.
