high temperature resistance (flame resistance) power cable
http://www.ahdqjt.com time: 11/07/10 09:42
it is used as power transmission cable for electric equipments of rated voltage 0.6/1kv or lower in bad environment or that with high temperature.
executive standard: enterprise standard
performance in usage:
- rated voltage u0/u: 0.6/1kv
- max. working temperature allowed by cable is 200℃ for cable with fluoroplastic insulation and sheath, 105℃ for cable with fluoroplastic insulation, 105℃ heat resistance and pvc sheath, and 180℃ for cable with fluoroplastic insulation and silicon rubber sheath.
- max. temperature of cable conductor is no more than 250℃ during short circuit(the longest lasting time is no more than 5s)
- temperature for installation is no less than -15℃
- bending radius of cable as follows:
it is no less than 20 times that of cable outer diameter for cable with single core
it is no less than 15 times that of cables outer diameter for cable with 3 cores
- power cable with fluoroplastic insulation and sheath has good features of chemical corrosion resistance, high temperature resistance and flame retardance
