What does the Polish cable designation 'OnG' mean?

In Polish standard PN-91/E-90103 nomenclature: 'O' stands for 'przewód oponowy' (heavy tire-grade rubber-sheathed flexible cable); 'n' stands for 'niepalny i olejoodporny' (flame-retardant and mineral-oil-resistant outer sheath); and 'G' stands for 'górniczy' (approved for mining service).

How does OnG compare with H07RN-F and NSSHÖU?

OnG bridges the gap between harmonised H07RN-F and German DIN VDE 0250-812 NSSHÖU: it uses +90 °C EPR core insulation (GIE1) rather than +60 °C EI4, and is produced in both 450/750 V (PN-91/E-90103) and heavy-duty 0.6/1 kV (PN-89/E-90143) executions with a mining-grade flame-retardant polychloroprene outer sheath (ON-3).

Where is OnG permitted in underground mines?

Under Polish mining regulations, OnG is used for mobile and semi-fixed electrical equipment in open-pit mines, coal preparation plants and underground mine excavations outside methane-hazard Degree 'b' and 'c' face zones (where screened cables such as OnGc or NSSHÖU/SSHCÖU are required).

Is OnG available with tinned copper conductors?

Yes. Both bare annealed Class 5 copper (standard per PN-91/E-90103 with polyester separator tape) and tinned Class 5 copper conductors are available on request.
