1.8/3kv Power Cables Three Cores Cables to IEC 60502 Standards
IEC 60502 Part 1(1.8/3KV)

1.8/3kv Power Cables Three Cores 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.

1.8/3kv Power Cables Three Cores 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 applied on top of a semi-conducting tape.
Insulation: Insulation is of polyvinyl chloride (PVC) intended for 1.8/3.6KV and 3.6/6KV cables, cross-linked polyethylene compound (XLPE)

Insulaton Screen:  The insulation screen consists of an extruded layer of non metallic, semi-conducting compound extruded over the insulation of each core. The extruded semi- conducting layer shall consist of bonded or cold strippable semi-conducting compound capable of removal for jointing or terminating.
Inner Covering & Fillers: The inner covering and fillers are made of non hygroscopic material like polypropylene.
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):  It consists of either flat galvanized steel wire armour (strip), round galvanized steel wire armour, and double steel tape armour.
Outer Sheath: PVC, PE, HDPE, MDPE or LSZH
