SANS Type 61A Cable

Description

SANS Type 61A 0.64/1.1 kV cable is a heavy-duty flexible low voltage trailing line constructed with Class 5 flexible stranded tinned annealed copper conductors, robust EPR insulation, individual tinned copper and nylon composite screens, and a heavy-duty polychloroprene outer sheath reinforced with an open nylon braid. This exceptionally resilient cable features three screened power cores and three unscreened pilot cores arranged symmetrically around a central core matrix, making it the ideal solution for heavy-duty trailing and reeling applications on mobile electrical machinery, drilling rigs, and conveyors in hazardous mining environments.

The range fully satisfies the stringent design and manufacturing protocols of SANS 1520-1 for low voltage flexible trailing cables used in mining operations, alongside material quality benchmarks SANS 1411-1 for conductor flexibility and SANS 1411-3 for advanced rubber insulation and sheathing performance. Featuring a standard rated voltage of 640/1100V, this cable provides dependable, safe power distribution in the most demanding hazardous and heavy industrial environments where excellent resistance to flame retardancy, UV light, ozone, and industrial oils is required.

For optimum performance and to prevent structural deformation of the core array, the cable must be installed with a minimum bending radius of 6 times the overall cable diameter during handling and active dynamic operations. It is designed to safely operate within a temperature envelope of -25°C to +90°C, ensuring that all low voltage terminations are completed using compatible heavy-duty trailing accessories to preserve total operational durability
