Mine roadway & tunnel wall hangers
High-ampacity +90 °C feeder for underground gallery pumps, ventilation fans, and auxiliary drives.
Product
OnGc-G is a Polish-standard 0.6/1 kV heat-resistant unscreened flexible mining rubber power cable manufactured to PN-G-90102. The 'c' designation denotes +90 °C heat-resistant EPR insulation for higher current-carrying capacity, while '-G' certifies
Typical values for this cable type, based on PN-G-90102 / ZN-TF-203 — confirmed in the datasheet and quotation for your order.
Application fit
Engineered for higher-ampacity 0.6/1 kV power distribution to underground mine pumps, fans, drilling jumbos, and roadway machinery where unscreened feeders are permitted.
High-ampacity +90 °C feeder for underground gallery pumps, ventilation fans, and auxiliary drives.
Flexible trailing connection for mobile skid units, crushers, and non-screened underground equipment.
Well suited to mobile drilling rigs and heading feeders requiring elevated thermal margin.
Permissible for light mono-spiral cable drums; use NSHTÖU for high-tension dynamic reeling.
NSHTÖU 0.6/1 kVUnscreened construction; select OnGcekż-G or (N)SSHCÖU when EMC or pilot earth monitoring is required.
