Refractory cable refers to the cable that can maintain safe operation for a certain period of time under the condition of flame burning.
1.The voltage is stable and durable
2.High puritypure copper: Adopting 99.99% high-quality oxygen-free copper, bright colour
3.Quality environmentally-friendly PVC insulation: Adopting environmentally-friendly insulating plastic, flame-retardant, anti-freeze, oil-resistant, fire-resistant, longer service life
4.Low eccentricity uniform thickness: The thickness of insulation is uniform,which can prevent the current breakdown
Fire-resistant cables are widely used in high-rise buildings, subways, underground streets, large power stations, and important industrial and mining enterprises and other places related to fire safety and fire safety, such as power supply lines and control lines for emergency facilities such as fire fighting equipment and emergency guidance lights.
Ordinary refractory cables are divided into Class A and Class B: Class B cables can withstand burning for at least 90 minutes in flames at 750 ° C to 800 ° C and at rated voltage without the cables being punctured (ie, 3A fuses will not blow). On the basis of improving the refractory layer manufacturing process and adding the refractory layer, a Class A refractory cable was developed. It can withstand burning for at least 90 minutes in a flame of 950 ° C to 1,000 ° C and a rated voltage without the cable being broken (That is, the 3A fuse does not blow). The fire resistance of Class A refractory cable is better than Class B.
