BS 6701B
♦Flexible Plain Annealed Copper Conductor
♦LSZH (Low Smoke Zero Halogen)
♦Temperature Limits: -15°C to +90°C
♦Standard: BS EN 50525-3-41
BS 6701B is a British Standard for low voltage LSOH cables. Also know as 2491B
BS6701B is a flexible, flame retardant panel wire that is used for applications where smoke and toxic fumes from a fire could threaten life or equipment. It is also used for:
| Working voltage | 300/500v (2491B), 450/750v (6701B) |
|---|---|
| Test voltage | 2000 / 2500 volts |
| Minimum bending radius | 5xOverall diameter |
| Flexing temperature | -15 oC to +90 oC |
| Static temperature | -40 oC to +90 oC |
| Insulation resistance | 10 MΩxkm |
| Halogen free acc. to EN 50267-2-1 / IEC 60754-1 | |
| Smoke density acc. to EN 50268-2 / IEC 61034-2 | |
| Corrosivity of gases acc. to EN 50267-2-2, IEC 60754-2 | |
| Flame retardancy acc. to EN 50265-2-1, IEC 60332-1 |
Single core 6701B flexible cable is used for wiring appliances and for use in metering and switchgear. Due to the low smoke zero halogen outer sheath they can be used in areas of high pedestrian footfall such as hospitals, supermarkets, airports and offices where toxic fumes and emissions would be a health hazard. The flexible single core cable features flexible plain annealed copper conductor and an LSZH outer sheath.
