Multiconductor
Flexible cables for winding in harsh environments
These type of cables are required for extra-heavy duty industrial use. These are power cables, reinforced portable low voltage, to be used in mining developments for heavy mobile equipment such as drag cables, shovels, drills and power feeders. This type of cable is required for extra-heavy duty industrial use. In oil fields it is used for feeding mobile drilling equipment, and in general for mobile outdoor installations with vertical and horizontal movement. It can withstand, while fixed or in movement, all types of efforts: traction, torsion, and flexion; caused by standard cable winding equipment. It counts with plastic materials which provide suitable protection against chemical products, harsh environment, tear and impacts.
