Applications
A single-core medium voltage power cable is a type of electrical cable designed to transmit electrical power at medium voltage levels. The single core cables are designed for the distribution of electrical power with nominal voltage Uo/U ranging from 1.8/3KV to 26/35KV and frequency 50Hz. Single-core medium voltage power cables are commonly used for distributing electrical power in industrial plants, utilities, renewable energy projects, and other applications where medium voltage is required.
Conductors:
Plain annealed copper or aluminium complying with IEC 60228 class 1 or 2.
Insulation:
Insulation is of polyvinyl chloride (PVC) intended for 1.8/3KV and 3.6/6KV cables, cross-linked polyethylene compound (XLPE), or ethylene propylene rubber (EPR/HEPR).
Screen:
The conductor screen consists of an extruded layer of nonmetallic, semi-conducting compound firmly bonded to the insulation to exclude all air voids. The conductor screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3KV and 3.6/6KV cables.
Jacketing:
Overall 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).
