STA PVC Sheath Armoured Electrical Cable XLPE Insulated For Power
Station
The basic structure of power cables by the core (conductor), an
insulating layer, a shielding layer and a protective layer of four
parts.
Electric cable with copper conductors, XLPE insulation, PVC
bedding, double galvanized steel tapes armour (STA) and PVC outer
sheath
1. The conductor is conductive part of power cable, which is used
to transfer power, is the main part of the power cable.
2. Insulation is the line between the core and the earth and the
different phase of wire core in the electrical insulated from each
other, is an indispensable part in the structure of power cable.
3. Shield 10KV power cable shielding layer and more generally have
a conductor shielding layer and an insulating shielding layer.
4. Protective layer The role of the protective layer is to protect
the power cable from the outside world the invasion of the
impurities and moisture, and prevent the external force directly
damage the power cable.
