CODE of CABLE
- TYPE 307S
INTRODUCTION
Type 307S cables are suitable for fixed installation and flexible operation as power supply cables to excavating, crushing machines and equipment, etc., in deep mines where explosive gasses and dust can accumulate and on surface. The cables are used with coal cutters in cable chains and similar face equipment.
SECTION RANGE
- From 50mm2 up to 240mm2
CONDUCTOR QUANTITY
- Three phase cores with composite individual screens and one unscreened pilot unit with three thinner cores 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
