Described lapping layer adopts glass fiber flame retardant oxygen barrier band overlap wrapped.
Described low smoke and zero halogen oxygen barrier layer adopts oxygen index 45 and above high flame resistance, low smoke flame-resistant polyolefin oxygen barrier material.
Described sheath adopts oxygen index 32 and above low smoke halogen-free flame-retardant polyolefin plastics.
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.Toxic gas can not be produced, contaminated environment time discarded.
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 is due at outer jacket member inwall with lead to adopt between core assembly and support and connect, 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, therefore has good anti-signal disturbing function.
