Application: Welding cable
Conductors: Tinned Cu Conductors
Insulation: EPR (Ethylene propylene rubber)
Core identification: Black
Sheath: CSP (Chlorosulphonated polyethylene)
more commonly known as HOFR (Heat & oil resistant & flame retardant)
Color: Black and orange
Voltage: 100V (450V for non-welding applications if suitably protected from mechanical damage).
Operating temperature: Maximum 85°C, minimum bending -20°C
Min bending radius: 6 x overall diameter
Ambient air temperature: 25°C
Max conductor temp: 85°C
Ambient temperature:
Cable operating temperature also varies according to the prevailing ambient temperature. EPR/CSP cables are designed to give optimum performances up to an operating temperature of 85°C at an ambient temperature of 25°C. The reduction factors for increased ambient temperatures are:
Standards:
BS638 Part 4: flexible cables, arc welding.
