CABLE CONSTRUCTION

Conductor : Copper conductor according to BS EN 60228 class 1/2.

Insulation : Fire resistant special ceramized silicone rubber compound type EI 2 as per BS EN 50363-1.

Screened : One or more metallic or laminated metallic tape(s) shall be applied, either longitudinally or helically or

a combination of both, with the metallic element in contact with the uninsulated circuit protective conductor or

drain wire.

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

insulated conductors in the two,three and four cores cables.

Sheath : Extruded LSZH type LTS 3 according to BS 7655-6.1.

Insulation Option : UV resistance, hydrocarbon resistance, oil resistance, anti-rodent and anti-termite properties

can be offered as option.
