INTRODUCTION

Type 307 cables are used in underground mining applications for fixed installation and flexible operation as power supply cables to motors, distribution boards, and other devices. The cables are utilized in cable chains (cable handlers) and other face equipment with coal cutters.

SECTION RANGE

  • From 25mm2 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
