Maximum allowable temperature of the conductor during short circuit, insulation ℃, insulation ℃
Product performance
/>The conductors of fire-resistant wires and cables comply with the regulations of /.
According to the different fire resistance levels, the fire-resistant insulation layer uses synthetic mica tape and phlogopite tape. Class fire-resistant cable, the refractory layer is made of synthetic mica tape, its fire resistance grade is ℃. Class fire-resistant cable, the refractory layer is made of phlogopite mica tape, its fire resistance grade is ℃.
The plastic insulation thickness of fire-resistant wires and cables is the same as the insulation thickness of the corresponding ordinary wires and cables.
The outer diameter of fire-resistant wires and cables is slightly larger than the corresponding ordinary wires and cables due to the addition of a fire-resistant insulation layer.
Ampacity of fire-resistant wires and cables The ampacity of fire-resistant wires and cables should not be lower than that of the corresponding ordinary wires and cables.
Fire resistance characteristics
Fire-resistant wires and cables should pass/specify the fire-resistant test. They can burn when a voltage is applied at a flame temperature of ℃
minutes or when a voltage is applied at a flame temperature of ℃. Minutes, the connection fuses continuously.
Class fire-resistant wires and cables should pass/specify the class fire-resistant test, which can be carried out at a flame temperature of ℃, applying voltage, burning for minutes, and connecting the fuse continuously.
Low smoke halogen-free 0.6/1KV and below plastic insulated power cable
