APPLICATION:
The cable is intended for use in mines with underground pits, threatened by fire and gas and coal dust explosion (methane pits). It is used for connecting machines for cutting and loading coal, machines for making underground corridor, as well as for supplying appliances and devices, electrical lighting and auxiliary electrical circuits.
Permissible conductor temperature:
– max operating temperature +90°C,
– in short circuit (max 5 s), max +250°C
Permissible ambient temperature:
– mobile from -25°C to +40°C,
– fixed laying from -30°C to +40°C
Smallest bending radius: 5D (D – cable diameter)
