Cable is scrapped, and burning causes power breakdown to cause any property loss and threaten the person rapidly in case of fire lower jacket, insulating materials
Safety.But the fire-retardant and fire protecting performance of cable is bad at present, especially under some emergency cases, the height that fire generates is softheartedly
Under condition, just it is easy to make existing cable bad.Therefore there is fire-resisting cable, fire-resisting cable refers in flame combustion
It can keep the cable of certain time safe operation.China's standard GB/T 12666.6（Wait IEC331）Divide fire resistance test to A, B
Two kinds of ranks, A grades of 950 ~ 1000 DEG C of flame temperatures continued for fiery time 90min, B grades of 750 ~ 800 DEG C of flame temperatures, lasting to supply
Fiery time 90min, during entire experiment, sample should bear load voltage value as defined in product.Fire-resisting cable is widely used in height
The ground related with fire safety and fire-extinguishing and lifesaving such as layer building, underground railway, undergrond street, large-scale power station and important industrial and mining enterprises
Side, and require to adapt to cable under the scene of fire wind occurred, the situations such as drench with rain, shake and still need to power supply for a period of time, with person who happens to be on hand for an errand
Member withdraws, rescues.Now in country's cable fire-resisting cable product, most fire resistance period is shorter, and flame retardant property is not outstanding enough, existing
A kind of a kind of fire-resistant cable that can solve the problems, such as this is provided.
