Conveniently install and use, conveniently sheath strip off, and in order to strengthen the anti-pull-off force of electric wire.This low-smoke, zero-halogen is provided with more than one nylon and tears rope between described metal screen layer and described sheath.
The utility model has the following advantages:
1, the utility model has excellent insulation property and mechanical performance, when a fire, the dense smoke hindering vision and the toxic gas causing people to suffocate can not be discharged, not there is combustibility, the propagation of flame caused by electric wire can be suppressed, ensure normal power-up in fire, transmit various control signal, alarm signal.
2, toxic gas can not be produced when the utility model is discarded, contaminated environment.
3, flame retardant coating of the present utility model has good fire resistance, resistance to acids and bases and withstands corona, radiation-resistant characteristic, and has fine flexibility and hot strength, is suitable for high-speed coiling.
4, the utility model have explosion-proof, corrosion resistance is strong, ampacity is large, radiation hardness, mechanical strength are high, volume is little, lightweight, life-span long, smokeless feature.
5, the utility model leads core assembly owing to adopting support to connect each group, and therefore Stability Analysis of Structures, not easily offsets distortion.
6, the utility model is led core assembly and is distributed in the form of a ring due to each group, and outer jacket member has metal screen layer, therefore has good anti-signal disturbing function.
7, the utility model is is conveniently installed and used, and hauls nylon and tears rope and conveniently sheath strip off, and can strengthen the anti-pull-off force of electric wire.
