Fixed installation
Primary UKOOA medium-voltage feeder for exposed offshore cable racks and MV switchgear rooms.
Product
BS 6883 Armoured MV Offshore Power Cable is engineered for medium-voltage offshore topside generation, gas compressors, water-injection pumps, and FPSO HV switchboards across 1.9/3.3 kV, 3.8/6.6 kV, 6.35/11 kV, and 8.7/15 kV ratings, featuring Class 2/5
Typical values for this cable type, based on BS 6883 / IEC 60092-354 (1.9/3.3 kV to 8.7/15 kV Offshore MV) — confirmed in the datasheet and quotation for your order.
Application fit
Engineered for main turbine-generator feeders, 6.6 kV / 11 kV seawater injection and export pumps, gas-compression drives, and inter-module MV ring mains on offshore platforms and FPSOs.
Primary UKOOA medium-voltage feeder for exposed offshore cable racks and MV switchgear rooms.
Peelable outer semi-conductive insulation screen simplifies 3.3–15 kV cold-shrink and heat-shrink MV terminations.
Tree-retardant Type GP5 HV-EPR insulation resists moisture ingress without requiring heavy lead sheaths.
Fixed offshore MV feeder cable per BS 6883.
