640/1100V trailing cable

24 Min Read
When sourcing a flame-retardant alternative to Prysmian Type 7 1.1kV mining cables for use in Australian underground coal mines, the appropriate specification is AS/NZS 1802 Type 241 (1.1/1.1kV). The AS/NZS 1802 Type 241 cable provides complete electrical and mechanical compliance with Australian mining safety regulations, features enhanced flame-retardant properties through heavy-duty PCP or CPE elastomer sheathing, and employs a symmetrical earth conductor architecture that ensures precise earth leakage fault detection—a requirement that the original British BS 6708 Type 7 cannot satisfy. For heavy mechanized equipment such as continuous miners, Type 241 is the standard selection; for lighter handheld drilling equipment, AS/NZS 1802 Type 210 is often preferred. Type 241 delivers the same operational functionality as Type 7 while meeting the strict electrical safety requirements of the Australian Standards and the WorkSafe framework that governs underground coal mining operations.

What is BS6708 Cable?

British Standard BS6708 sets out the requirements for flexible trailing cables where used in mining operations and quarries. These cables are often referred to as trailing cables, quarry cables, or auxiliary cables and have applications with a wide range of dynamic mining equipment including excavators, coal-cutters, crushing machines, and shuttle cars. flexible trailing cable, mine cable, EPR mining cable, SWA mining cable, chloroprene cable, coal cutter cable, excavator cable, shuttle car cable, crushing machine cable, coal face cable, Type 7 mining cable, Type 7M cable, Type 7S cable, Type 11 cable, Type 20 cable, Type 21 cable, Type 307 cable, Type 331 cable, Type 621 cable, Type 631 cable, 640/1100V mining cable, 1.9/3.3kV mining cable

What is Type FS4 BS 6708 Trailing Cable?

The BS 6708 Type FS4 trailing cable represents a specialized category of non-armoured, individually metallic screened flexible cables engineered specifically for demanding mining and quarrying applications. This cable type is distinguished by its unique flat configuration design, where three phase cores and one pilot core—each equipped with composite individual screens—are laid up around an elastomeric cradle in contact with each other. This construction methodology provides optimal electrical performance while maintaining the flexibility essential for dynamic mining operations. Key Identification: Type FS4 cables are specifically designated for overhead catenary systems and similar power supply applications in environments where explosive gases and dust may accumulate. The rated voltage of 640/1100V and test voltage of 3kV ensure reliable performance under the most challenging mining conditions.
