CODE of CABLE
- TYPE 7
INTRODUCTION
Type 7 mining cable is generally used in deep mines where explosive gasses and dust can accumulate and on the surface for supplying excavating, crushing machines, and equipment.
SECTION RANGE
- From 16mm2 up to 150mm2
CONDUCTOR QUANTITY
- Three phase cores with composite individual screens and one unscreened pilot core laid up in contact with each other and the bare earth conductor in the centre.
COLOUR CODE of CABLE
- Insulation Colour code could be according to the International Standards or customer’s request/demand.
NOTE: These cables should not be installed at temperatures below -40°C or above 80°C
