FAQ

Questions engineers ask first

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

How does OGc differ from underground '-G' cables like OnGc-G or OnGcekgż-G?
OGc lacks the '-G' underground mine suffix and phase screens, as it is engineered specifically for surface open-cast lignite mines, quarries, mobile substations, and overland conveyor drives operating at 0.6/1 kV, 1.8/3 kV, and 3.6/6 kV in cold outdoor environments down to -40 °C.
Why is OGc widely used in 1.8/3 kV and 3.6/6 kV single-core and four-core versions?
Open-cast mines and quarries frequently use single-core OGc cables as flexible jumpers inside mobile transformer stations and 3+1 core OGc cables to feed belt-conveyor drive heads, pontoon dewatering pumps, and mobile crushers. 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 temperature rating does the 'c' in OGc provide?
The 'c' designation specifies +90 °C heat-resistant ethylene-propylene rubber (EPR) insulation with a +250 °C short-circuit rating, allowing higher continuous current loads under summer solar radiation on exposed quarry benches. 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 NTSCGEWÖU be chosen instead of OGc?
Choose NTSCGEWÖU when the medium-voltage cable must be wound dynamically under high tension on motorized excavator drums or requires semi-conductive and copper phase screens for earth-fault monitoring. 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.
