Rubber & Crane Cables
Coil End Lead to BS6195 Type 4
| Options | |
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
