FAQ

Questions engineers ask first

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

What does the '/w' symbol indicate in OnGcekż/w-GW and O2nGcekż/w-GW?
The '/w' designation indicates a double-screened architecture: in addition to the individual semi-conductive and copper screens ('ek') around each MV phase core and pilot bundle, a second collective screen surrounds the entire laid-up core assembly directly beneath the outer sheath. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
Why is double screening ('/w') specified for 1.9/3.3 kV and 3.6/6 kV longwall shearer cables?
If a sharp metal object or rock pierces the outer jacket on a 3.3 kV or 6 kV longwall face, it contacts the outer collective '/w' earth screen first, guaranteeing an immediate earth-leakage trip before the object can reach the phase cores. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
What is the difference between OnGcekż/w-GW and O2nGcekż/w-GW?
Both feature double screening ('/w') and longitudinal water blocking ('-GW'), but O2nGcekż/w-GW upgrades the outer covering to a double-layer ('O2n') reinforced polychloroprene sheath for higher tear strength and axial pulling forces in Bretby cable handlers. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
Which voltage ratings are most common for OnGcekż/w-GW?
It is most widely deployed in 1.9/3.3 kV (Um 3.6 kV) for modern high-capacity longwall coal shearers and armored face conveyors, as well as 3.6/6 kV (Um 7.2 kV) for heavy roadheaders and mobile face transformers. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
