FAQ

Questions engineers ask first

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

What is the difference between OnGcekż-GW and standard OnGcekż-G?
The 'W' (wodoszczelna) suffix in OnGcekż-GW indicates a sealed, water-blocked construction that incorporates hydro-swelling tapes and moisture-blocked interstices, preventing mine water from travelling longitudinally along the cable into flameproof switchgear if the outer jacket is punctured. 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 longitudinal water blocking critical on longwall shearer faces?
High-pressure dust-suppression water sprays at the cutter drums and flooded floor pans frequently immerse trailing cables; longitudinal water barriers stop capillary water migration that would otherwise corrode copper strands and trigger earth-leakage trips at gate-end boxes. 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.
Does the '-GW' water-blocking system reduce cable flexibility in Bretby handlers?
No, the non-woven hydro-swelling tapes and elastomeric core bedding are engineered to flex smoothly inside longwall Bretby cable handler chains while maintaining the same 10 × D mobile minimum bending radius as OnGcekż-G. 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.
When should OnZGcekż-GW(A) be selected over OnGcekż-GW?
Select OnZGcekż-GW(A) when the cable is subjected to severe axial pulling forces, rockfalls, or high mechanical crushing, as the 'Z' and '(A)' features add an anti-torsion/anti-crush reinforcement braid embedded in a dual-layer 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.
