OnGcekżi-G 0.6/1 kV Individually Screened Intrinsically Safe & Control Mining Cable

Small mobile mining machines, drills, pumps and auxiliary drives often run pilot and control circuits through the same trailing cable as the power supply. OnGcekżi-G, also written OnGcekzi-G, is the 0.6/1 kV construction for that duty in which the letter i marks individual screening: every power core and every pilot core carries its own composite tinned copper/fibre braid with 65% coverage, so each circuit is separately screened and a damaged core faults to its own screen.

The three power cores and one or more pilot cores, all insulated with EPR type IEP, are laid up around a bare flexible tinned copper earth conductor and protected by a heavy-duty ON-5 polychloroprene sheath that is ozone, sun, weather and oil resistant and flame retardant. The reference schedule covers nine layouts from 3×1.5+1.5+1.5 mm² to 3×25+16+4 mm², with outer diameters of 14.9 mm to 34.9 mm and current ratings of 28 A to 152 A. The 3×1.5+1.5+3×1.5 mm² layout is listed in two sheath schedules, 3.2 mm and 3.5 mm.

The individually screened pilot cores keep control and monitoring signals separate from the power cores; suitability for an intrinsically safe circuit depends on the certified system and its cable parameters, which the system designer confirms. Use OnGcekż-G for larger three-core screened trailing cable and 1-CBEH where a gassy-mine cable with control and monitoring cores is specified.

OnGcekżi-G (OnGcekzi-G) 0.6/1 kV Cable Construction & Individual Screens

The representative horizontal sample shows OnGcekżi-G 3x4+4+2x4 mm²: three EPR-insulated tinned copper power cores and pilot cores, each under its own tinned copper/fibre braid screen, laid up around a bare tinned copper earth conductor under a black ON-5 polychloroprene sheath.

OnGcekżi-G Type Designation Breakdown

• O: flexible rubber-sheathed (oponowy) cable
• n: oil-resistant, flame-retardant polychloroprene sheath
• G: mining (górniczy) duty
• ek: screened cores with pilot (control) cores
• ż: protective earth conductor, bare at the centre
• i: individual screen on every power and pilot core

OnGcekżi-G 0.6/1 kV Mining Applications & Duty Scope

Use OnGcekżi-G where power, pilot and control circuits share one small trailing cable and each core must be screened.

• Mobile drills, pumps, winches and auxiliary drives on 0.6/1 kV mine supplies.
• Machines whose pilot, monitoring or control circuits run beside the power cores and need individual screening.
• Light trailing duty in methane and coal-dust hazard areas, subject to the approval documents required by the mine.
• Replacement of in-service OnGcekżi-G cable in the nine reference layouts.

OnGcekżi-G vs OnGcekż-G, 1-CBEH and NSSHKCGEOEU Selection Boundary

Intrinsically safe circuit use depends on the certified system and its cable parameters, confirmed by the system designer.

OnGcekżi-G (OnGcekzi-G) Frequently Asked Questions

What does the i in OnGcekżi-G mean?

It marks individual screening: every power core and every pilot core has its own composite tinned copper/fibre braid with 65% coverage.

Can OnGcekżi-G be used in an intrinsically safe circuit?

The individually screened pilot cores separate control and monitoring circuits from power. Whether a cable may be used in a specific intrinsically safe circuit depends on the certified system and its cable parameters, confirmed by the system designer.

Why are there two entries for 3x1.5+1.5+3x1.5 mm²?

The layout is listed in two sheath schedules, 3.2 mm and 3.5 mm, with different diameters and weights. State the schedule you need when ordering.

What are the MOQ and lead time?

The minimum order quantity is 50 m and the manufacturing lead time is 7 to 45 working days, depending on layout and quantity.
