Medium Voltage Power Cable

Medium Voltage Power Cable

3.6/6 kV 6/10 kV 8.7/15 kV 12/20 kV 18/30 kV

Application

MV Power Cables are designed to operate at voltages up to 18/30 (36) kv and are typically used in medium-voltage distribution networks. The conductors can be made from copper or aluminum, and are usually stranded and compacted to form a round, insulated core. Cable sizes can range from 25 up to 630 sq.mm per core, with 1 or 3 insulated cores making up the cable. Various protective measures can be employed, such as construction and materials for direct burial, longitudinal and/or radial water tightness, anti-termite protection, and fire safety.

Construction

Formation 1 core, 3 core, 3×1 core Triplex
Conductor Cu or AL, Stranded Circular, Stranded Compact Circular, Milliken Segmented
Insulation XLPE or TR-XLPE or EPR
Metallic screen or sheath Copper Wire Screen (CWS), Copper Tape Screen (CTS), Lead alloy sheath (LAS), Corrugated Aluminium sheath (CAS), Corrugated Copper sheath (CCU), Corrugated Stainless Steel (CSS), Aluminium poly laminated (APL), Copper Poly Laminated (CPL), Aldrey wire screen (AWS)
Armoured Aluminium Wire Armoured (AWA), Steel Wire Armoured (SWA), Stainless Steel Wire Armoured (SSWA)
Termite Protection Polyamide Nylon Jacket, Double brass tape (DBT), Cypermethrin
Bedding/ Separation sheath/ Over sheath PVC, LSHF, LDPE, MDPE, HDPE
