Flame Retardant Flexible Trailing Cable
Request a Quote
Welcome to Leshan Cable, where our expansive catalogue covers everything from sheathed cable to bare conductor. Shown on this page is the Leshan flexible cable.This flame retardant flexible trailing cable is used for the electric power supply of coal mining machines. Machines such as coal-dredgers, loading machines, conveyers, electric drills, and transformer substations. The conditions in mining can be tough on equipment and that means that components must be built with this in mind. This trailing cable has a thick insulating sheath that protects the conductors within and the user from harm.
The product is built to the standard
MT818.1~10-2009. The coal mine uses soft ambulation type of flame-resistant cable.
Usage characteristic of flexible rubber cable for mining purposes
1) U0/U Respectively is 0.3/0.5kV, 0.38/0.66kV, 0.66/1.14kV,1.9/3.3kV and 3.6/6kV
2) The long-term allowable working temperature of the electric cable conductor is 65℃ for common insulators and 90℃ for EPR insulation.
3) The minimum bent radius of the cable is 6 times the cable diameter
4) Keep out of direct sunlight for extended periods.
