SANS Type 41 & Type 61 Flexible Trailing Cables

Our range of Type 41 and Type 61 (61a and 61b) are part of our Mining industry portfolio, as low voltage cables for reeling and non-reeling industrial applications and flexible trailing applications including submersible pumps, loaders, drilling rigs, low haulage dumpers and conveyors

Type 41 and Type 61 cables have a rated voltage of 640/110V, along with a robust Polychloroprene Rubber (abbreviated CR) or thermoplastic Polyurethane  (TPU) outer sheath to provide a protective barrier against many of the environmental and physical challenges a cable will find when in use. They includes Ozone and UV resistance, chemicals and abrasion resistance, heat resistance, and low flammability. The TPU sheathing on the Type 61a cable is highly recognisable as transparent with an orange and silver reflective tape underneath.

Type 41 and Type 61a cables have 6 core cables, with 3 phase cores of tinned annealed copper, 2 pilot cores, and 1 (or 2) earth continuity cores. The phase cores are insulated with Ethylene Propylene Rubber (EPR). They have a wide operating range, suitable for mining operations around the world, from -40oC to +90oC

Both Type 41 and Type 61a cables meet the requirements of the South African Standards Bureau SABS 1520 Part 1 for low and medium voltage cables. For higher voltage cables cables for similar applications, please see our Type 611, 622 and 633 cables.
