Fire insulation layer flame retardant power cable features

(1) the main technical fire insulation layer flame retardant cable is the cable insulation with a layer of non-toxic, smoke-free, no melting, no burning, no halogen fireproof glue is filled between the core and the outer sheath, when the cable when burning, refractory compound thermal decomposition, release of crystal water and heat, and the formation of the the insulating surface layer. Cover layer from the combustion of oxygen, so that the inner insulating organic protected; crystal water precipitation, evaporation of water vapor absorbs heat, reducing the temperature of the surrounding environment, therefore, the cable will gradually extinguish fire.

(2) the fire layer technology treatment containing halogen flame retardant cable combustion smoke density is improved obviously, if coupled with the low smoke halogen-free insulation and sheath, halogen-free, low toxicity, low smoke, but also meet the requirements of the.

(3) the length of the cable insulation ablation short, fireproof layer resistance cable by 815 ℃ flame spraying 40min XLPE cable insulation, the basic intact.

(4) the flame retardant property of the cable is stable and reliable, and the product of low price.

The main Fire insulation layer flame retardant power cable technical performance

(1) prescribed fire isolation layer flame retardant cable flame retardant grade IEC60332-3, class a test in GB/T18380.3 standard.

(2) the cable conductor long-term permissible maximum working temperature of cross-linked polyethylene insulation is 90 ℃, 70 ℃ for PVC insulation.

(3) when laying the cable, the lowest temperature was 0 ℃.

(4) allowable bending radius of the cable, allowing short circuit temperature, load flow, laying conditions, the use of occasions, the installation method may be of the same specifications as equivalent non fire insulation layer of the cable.

(5) rated voltage U0 3.6kV and above power cables with cross-linked polyethylene insulation for partial discharge test. 1.73U0 voltage is applied in the finished cable, cable discharge shall not be more than 10pC.
