FAQ

Questions engineers ask first

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

What does 'ekg' mean in OnGcekgż-G compared with 'ek' in low-voltage OnGcekż-G?
In medium-voltage PN-G-90105 cables, 'ekg' denotes a full radial field-control screening system consisting of an inner semi-conductive rubber conductor screen, +90 °C MV EPR dielectric, and an outer semi-conductive rubber screen ('g') combined with metallic/elastomeric earth screening to eliminate partial discharge at 3.6/6 kV and 6/10 kV.
Which voltage ratings are covered by OnGcekgż-G?
OnGcekgż-G is manufactured in 3.6/6 kV (Um 7.2 kV, routine tested at 11 kV AC) and 6/10 kV (Um 12 kV, routine tested at 17 kV AC) ratings, also covering 3.3 kV longwall shearer and mobile transformer feeders. 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 OnGcekgż-G differ from OnGcrekgż-G(S) / OnGcrekgż-G(Z)?
OnGcekgż-G uses a composite elastomeric/copper phase screen for general MV trailing and roadway distribution, whereas OnGcrekgż-G(S)/(Z) adds a dedicated copper wire/tape radial screen ('r') and S/Z anti-torsion armouring for higher fault currents and dynamic reeling. 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.
Can OnGcekgż-G be supplied with multiple pilot cores or optical fibres?
Yes, in addition to the standard 1×6 mm² or 1×10 mm² pilot core for earth-loop continuity, OnGcekgż-G can be manufactured with a 3- or 4-core pilot bundle or an integrated fibre-optic element. 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.
