Medium-voltage distribution systems begin at substations and supply electricity to a wide spectrum of power consumers. When selecting a cable, the basic aim is to safely provide adequate electrical power, with continuous and trouble-free operation as the failure of a major power cable is likely to have a considerable effect on the power transmission grid.
Each installation has particular requirements that must be considered. There are distinct benefits from specifying a copper or aluminium conductor cable that has been manufactured under rigid specification and quality control procedures. It will provide maximum performance with minimum maintenance.
These medium voltage cables are manufactured according to IEC 60502-2 standard (others standards can be selected on request). This IEC standard specifies the constructions, dimensions, test requirements and current ratings of power cables for rated voltage (U) from 6 kV up to and including 30 kV.
Cables described are radial field cables (single-core or three-core). They are provided with a copper screen on each core. Our standard production for those cables is with cross-linked polyethylene insulation (XLPE) but we also can use insulation materials such as PVC for non radial field cables or EPR up to 30 kV.
