Standard covering flexible trailing cables for use in mines and quarries.

British Standard BS6708 sets out the requirements for flexible trailing cables where used in mines and quarries. These cables are often referred to as trailing cables or auxiliary cables and have applications with a wide range of dynamic mining equipment.

Standard BS6708 covers a number of cable types according to their constructions, voltage ratings and applications, including heavy duty flexible trailing cable.

BS6708 reference Voltage Rating Flexible Trailing Cable Application
BS6708 Type 7, Type 7M, Type 7S 640/1100V For use on equipment including excavators, coal-cutters and crushing machines.
BS6708 Type 11 640/1100V For use with shuttle cars, coal cutters and at-face equipment
BS6708 Type 20 640/1100V For the supply of heavy-duty machinery used for excavating and crushing applications (3 core cables)
BS6708 Type 21 640/1100V For the supply of heavy-duty machinery used for excavating and crushing applications (4 core cables)
