FAQ

Questions engineers ask first

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

How does BS 6883 Type GP5 HV-EPR insulation differ from 0.6/1 kV Type GP4 EPR?
For voltages from 3.8/6.6 kV to 8.7/15 kV, BS 6883 specifies Type GP5 high-voltage EPR (BS 7655-1.2) triple-extruded in a closed vulcanization tube simultaneously with a bonded inner semi-conductive conductor screen and a strippable outer semi-conductive insulation screen, ensuring void-free partial discharge performance (≤ 5 pC).
When does BS 6883 require individual copper tape phase screens on MV cables?
Under BS 6883, 1.9/3.3 kV cables may be supplied either unscreened (collective armour earth) or screened, whereas all 3.8/6.6 kV, 6.35/11 kV, and 8.7/15 kV cables incorporate a semi-conductive screen plus a helically lapped tinned copper tape screen over each individual phase. Each production
Why are offshore medium-voltage BS 6883 cables typically sheathed in Red Type SW4?
On UKCS North Sea platforms and FPSOs, a Red outer SW4 halogen-free sheath visually distinguishes medium-voltage (3.3 kV, 6.6 kV, 11 kV, 15 kV) circuits from Black 0.6/1 kV LV power cables and Grey/Blue instrumentation cables along shared ladder racks. Each production drum undergoes
Why is Type GP5 HV-EPR preferred over XLPE for offshore platform medium-voltage feeders?
High-voltage EPR (Type GP5) is substantially more flexible than rigid MV XLPE, allowing tighter 8×D routing into compact offshore switchgear bays, and exhibits inherent resistance to water-treeing in humid marine atmospheres without requiring a heavy metallic lead sheath. Each production drum undergoes 100 %
