FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What is the difference between BS 6883 Type U and BS 6883 Type A offshore cables?
BS 6883 Type U is an unarmoured ('U') cable consisting of tinned copper conductors, Type GP4 EPR insulation, and a single Type SW4 halogen-free elastomeric outer sheath. BS 6883 Type A ('A') adds an inner elastomeric bedding, a galvanized steel or phosphor-bronze wire-braid armour, and an outer SW4 oversheath.
What are Type GP4 and Type SW4 elastomeric compounds under BS 6883?
Defined in BS 7655, Type GP4 is a 90 °C cross-linked ethylene-propylene rubber (EPR) core insulation with high insulation resistance and flexibility. Type SW4 is a heavy-duty cross-linked low-smoke zero-halogen (LSZH) synthetic elastomer sheath offering high tear strength, oil resistance, and < 0.5 % acid gas emission.
When should I specify BS 6883 Type U instead of NEK 606 or IEC 60092-353?
BS 6883 Type U (with UKOOA two-letter core/size codes) is the primary standard for UK Continental Shelf (UKCS) North Sea fixed production platforms, FPSOs, and brownfield tie-ins where heavier thermoset GP4/SW4 wall thicknesses are specified over thinner IEC 60092 shipboard cables. Each production drum
Are fire-resistant (IEC 60331) versions of BS 6883 Type U available?
Yes. By lapping a phlogopite mica-glass fire barrier tape over the tinned copper conductors beneath the GP4 EPR insulation, we supply BS 6883 / BS 7917 Type U fire-survival cables tested to IEC 60331-21 (750 °C / 830 °C for 90–180 minutes). Each production
