It applies to electrical power transmissiondistribution lines with A.C.rated voltage U0/U up toincluding 0.6/1KV. The flame retardant XLPE power cable is hard to get firethat the continuous burning of cables is very limited when it is on fire. It applies to the places with many cables laid tightly together such as power-generated station, subway, tunnel, high-storey building, large-size factorymines, oil fieldcoal mine. Main characteristics of low smoke, halogen-free, flame retardant power cable is very low smoke emission harmless (low toxic, low corrosive) besides the property of flame retardant. It can be used in such kinds of places as subway, tunnel, nub power station with special demands of property of flame retardant, the density of smoke emissiontoxic index when cable gets burning. Fire-resistance cable can operate normally for some time when it is burning except that it can transmit electrical power under normal condition. It is used in the places such as nub power station, subway, tunnel, high-storey buildingother places concerning to fire securityits lifesaving. Standards of products The cable is manufactured in accordance with the standards of GB/T12706.1-2002. It can also be produced accordance to special requirements put forward by clients. Besides, the standards mentioned above, the flame retardant property of the flame retardant cable must meet the corresponding demands of class A, B,C which is stipulated in GB/T19666-2005. Among the 3 classes, class A is best. Clients can any type of cable as practical needs. Low smoke, halogen-free, flame retardant power cable must meet the corresponding requirements of class A, BC. It must pass the test of smoke density GB/T17651-1998the test measuring the PH valueconductivity which is stipulated in GB/T17650.2-1998. Fire-resistance property of the fire-resistance cable can meet GB/T19216.21-2003.
