FAQ

Questions engineers ask first

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

What does each letter in OnGcekż-G stand for?

In PN-G-90101 nomenclature, 'On' denotes a mobile rubber-sheathed cable, 'G' stands for rubber core insulation, 'c' means +90 °C heat-resistant EPR, 'ek' designates semi-conductive elastomeric phase and control screens, 'ż' indicates auxiliary pilot control cores, and '-G' certifies underground mining flame retardance. 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.

How does the 'ek' semi-conductive screen protect underground longwall operators?

Each +90 °C EPR power core is enclosed in a semi-conductive elastomeric screen in direct contact with the bare protective earth conductor, ensuring that any rockfall or crushing fault immediately creates a phase-to-earth fault detected by the gate-end box leakage relay before phase-to-phase arcing can occur.

How many auxiliary control cores ('ż') can be integrated into OnGcekż-G?

Standard configurations include a collectively screened control core bundle containing 3, 4, 7, or 9 auxiliary cores (1.5 mm² or 2.5 mm²) used for pilot earth-loop monitoring, remote start/stop interlocks, and methane trip circuits. 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 OnGcekż-GW be specified instead of OnGcekż-G?

Specify OnGcekż-GW when the longwall face or heading is subject to heavy water ingress or standing water on the roadway floor, as the '-GW' construction adds longitudinal water-blocking elements and moisture-sealed sheathing. 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.
