CODE of CABLE

  • TYPE 7M

INTRODUCTION

The cables are suitable for fixed installation and flexible operation as power supply cables to motors, distribution boards, etc., in underground mining applications. The cables are used with coalcutters in cable chains (cable handlers) and similar face equipment.

SECTION RANGE

  • From 16mm2 up to 150mm2

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
