Insulating layer: the cable is processed by adopting a one-step method silane crosslinked polyethylene high polymer material, and the crosslinked polyethylene not only has good physical and mechanical properties, excellent chemical stability and excellent dielectric properties, but also improves the long-term service temperature of the cable (the working temperature of the cable can be kept at 90 ℃), and has excellent mechanical properties such as environmental stress cracking resistance and creep resistance; the products of the combustion of the crosslinked polyethylene are CO2 and H2O, so the crosslinked polyethylene has little harm to the environment during combustion, meets the requirements of modern fire-fighting, low smoke and no toxicity, and is a preferred insulating material for environment-friendly cables.
The first inner sheath layer, the second inner sheath layer and the third inner sheath layer are all made of low-density polyethylene materials, the low-density polyethylene has low density, the weight is light, later construction is facilitated, and when the follow-up sparse winding of a neutral conductor can be prevented, scratching is caused to insulation, and the insulation breakdown condition is prevented from occurring.
Fourthly, an outer conductor layer: the copper clad aluminum conductor is processed by the copper clad aluminum conductor, and the copper clad aluminum conductor has excellent elongation after annealing, so that the copper clad aluminum conductor has good flexibility and bending property, the power transmission is ensured, the installation and construction are convenient, and the laying cost of the cable is saved.
Fifthly, wrapping a flame-retardant wrapping layer: the high flame-retardant glass cloth belt is adopted for wrapping, and the outer conductor layer is fastened to be not loose; when the cable suffers from burning, a large amount of heat can be absorbed, a carbonization layer is formed, an air isolation layer and an insulation layer are protected from burning, and the loss of fire is prevented from further expanding.
Sixthly, the flame-retardant filling core: the flame-retardant high-density polyethylene composite material is processed by adopting a flame-retardant high-density polyethylene high polymer material, is resistant to corrosion of acid, alkali and various salts, has small permeability to water vapor and air and low water absorption, and can prevent a conductor from being corroded.
The outer protective layer: the environment-friendly one-step method silane crosslinking low-smoke halogen-free sheath material is adopted, and the flame retardant material is added into the plastic, so that the environment-friendly cable can completely ensure the building requirement of the environment-friendly cable on high fire prevention, the cable is not easy to burn in case of fire, and the spread of flame and the expansion of disasters after burning can be prevented; the halogen-free outer sheath solves the problem of secondary pollution formed during combustion of the cable, and avoids carcinogenic dioxin substances generated during combustion of the traditional PVC cable; the environment-friendly one-step method silane crosslinking low-smoke halogen-free material without environmental pollution is adopted, toxic gases such as HCL and the like are not generated in the production, use and combustion processes, the discharged acid gas is extremely little, the damage to personnel, equipment and instruments is small, and the environment-friendly characteristic is more obvious. The smoke generated by the cable during burning is extremely thin, which is beneficial to the evacuation of personnel and the fire extinguishing; the light transmittance of the product is greater than 40%, which is far higher than the standard that the light transmittance of the traditional flame-retardant cable is less than 20%.
