Conductor:Polycab 4.0 Sqmm 4 Core Copper Armoured Cable

High conductivity annealed plain stranded compacted copper /Aluminium conductor produced in-house from
state-of-the art machine.

Insulation:

In-house developed high insulation resistance cross-linked polyethylene thermoset insulation compound.

Laying Up:

In case of multi core, insulated cores are laid up together with in-house developed fillers to maintain circularity
of cable, wherever applicable.

Inner Sheath:

In-house developed PVC thermoplastic compound/ halogen free compound having low emission of smoke
and corrosive gases when exposed to fire and also ensures circular shape of cable.

Armour:

Aluminium / Galvanised Steel Round/stripe wire Armoured to give mechanical protection and also acts as return
path for earth fault current

Outer Sheath:

In-house developed PVC thermoplastic compound/ halogen free compound having low emission of smoke
and corrosive gases when exposed to fire for outer protection.
