CABLE CONSTRUCTION 

Conductors: Plain annealed copper wire, solid according to IEC(EN) 60228 class 1, stranded

according to IEC(EN) 60228 class 2.

Insulation: Mica glass fire resistant tape covered by fire resistant silicone rubber compound type EI2

as per BS 7655-1.1.

Cabling: The cores are cabled together in concentric layers with suitable non-hygroscopic fillers.

Overall screen: Aluminum/polyester tape with tinned copper drain wire.

Circuit Protective Conductor: Uninsulated tinned copper conductor of the same section and class

as the insulated conductors in the 2-, 3- and 4-core cables. Drain wire of 0.5mm2 tinned copper

conductor is provided in cables of more than 4 conductors.

Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1 (Thermosetting LSZH

compound type SW2-SW4 as per BS 7655-2.6 can be offered.)
