FAQ

Questions engineers ask first

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

What does the letter 'i' signify in OnGcekżi-G?
The 'i' (indywidualnie ekranowana) suffix indicates that every individual core inside the cable is enclosed in its own semi-conductive elastomeric screen, rather than sharing only a collective overall screen around a multi-core bundle. 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 do underground mine safety rules require individual core screening on control cables?
If a rockfall or hydraulic roof support crushes an unscreened multi-core control cable, two live control cores can bridge and accidentally start a conveyor or shearer; with individual core screens ('ekżi'), any insulation damage immediately contacts the earth screen and trips the circuit safely.
How does OnGcekżi-G differ from OnG1?
OnG1 is an unscreened +70 °C multi-core mining control cable for non-hazardous auxiliary circuits, whereas OnGcekżi-G features +90 °C EPR insulation ('c') and individual semi-conductive screens ('ekżi') on every core for fail-safe methane-hazard control loops. 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 is the semi-conductive screen stripped when terminating OnGcekżi-G?
During termination inside flameproof glands, the black semi-conductive elastomeric screen layer is scored and peeled back cleanly over the last 30–50 mm of each core so it cannot create a leakage path to the conductor lug. 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.
