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.
