3.6/6kv Power Cables Single Core Cables to IEC 60502 Standards
IEC 60502 Part 2

3.6/6kv Power Cables Single Core Cables to IEC 60502 Application
The single core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 1.8/3KV to 26/35KV and frequency 50Hz. They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.

3.6/6kv Power Cables Single Core Cables to IEC 60502 Construction

Conductor: Plain annealed copper or aluminium complying with IEC 60228 class 1 or 2. 
Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting compound firmly bonded to the insulation to exclude all air voids.
Insulation: Insulation is of polyvinyl chloride (PVC) intended for 1.8/3KV and 3.6/6KV cables, cross-linked polyethylene compound (XLPE)

Insulaton Screen:  It will consist of a layer of copper wires applied helically with overlap over insulation screen. Other combinations of metallic screens base on customs demand.
Separation Sheath (for armoured cable): The separation sheath comprises a layer of extruded PVC, PE or LSZH, applied under the armour .
Lapped Bedding : The lapped bedding consists of Polyester non woven fabrics .The thickness is1.5mm
Armour (for armoured cable): The armour consists of round galvanized steel wire armour applied helically over an extruded separation sheath.
Outer Sheath: Outer sheath comprises a layer of extruded thermoplastic compound (PVC, PE or LSZH can be offered as an option.) or elastomeric compound (polychlorprene CSP or chlorosulfonated PE).
