CONSTRUCTION :
Conductor: Flexible Tinned Copper to BS6360
Insulation: Ethylene Propylene Rubber E.P.R ; Type FR1 (Voltage Categories A & C) & Type FR2 (Voltage Categories D & E) to BS 7655.
Sheath: Chlorosulphonated Polyethylene C.S.P. HOFR Black. To BS 6899
APPLICATION :
This range of Cables is designed as power leads for permanent connecton to coil winding motors, panel wiring and electrical machinery . They are able to withstand high temperature and immersion in varnish. Other applications include vehicle wiring. T he HOFR sheath resists oil and varnish and the stranding is designed as a compromise between flexibility and positional stability. Also suitable as an alternative to tri-rated and bi-rated cable in certain applications
