clearcast LV Resin Cable Joints - Low Smoke Zero Halogen
Suitable for PVC or XLPE cable, 1kV

CTL LSZH resin cable jointDistinguished by its yellow-tinted injection-moulded shells, CTL’s range of Low Smoke Zero Halogen cable joints has been especially developed to meet the increasing demand for joints that match the characteristics of modern flame retardant, fire resistant and low smoke cables.

To reflect the specialist application, these joints can be installed without the need for dedicated tools or the application of heat.

All of the popular and well-established features of standard CTL cable joints have been retained. Internationally, there are several standards that regulate fire behaviour. CTL products conform to the following national standards:-

UK:- BS 476 Part 7,
Class 1Y rating.
Germany:- DIN 4102/part 1, B1 rating.
France:- NFP 92 501, 5 & 16, M2 rating.

A typical kit consists of an outer shell manufactured from UV stable , low smoke, zero halogen, flame retardant material that matches or exceeds the relevant properties of similarly specified cable.

For the majority of applications it is only the shell that requires specialist fire-sensitive properties. In these cases CTL’s standard two-part polyurethane resin is supplied in easy-mix pouches.

When specifications call for the resin to also be flame retardant, halogen-free and low smoke, joints are shipped with CTL’s CR171H resin which is flame retardent to V0 rating of UL94.
