Fig. 1 is the utility model ultraviolet light cross-linking high life low smoke, zero halogen fire-resistant environment-friendly type wire cross-sectional schematic diagram.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
Embodiment 1
Fig. 1 is the utility model ultraviolet light cross-linking high life low smoke, zero halogen fire-resistant environment-friendly type wire cross-sectional schematic diagram.
Present embodiment discloses the fire-resistant environment-friendly type electric wire of a kind of ultraviolet light cross-linking high life low smoke, zero halogen, its concrete structure as shown in Figure 1, comprise oxygen-free copper conductor 1, in the present embodiment, oxygen-free copper conductor 1 is the stranded cross section of stranded copper wire is circular conductor, and its copper wire adopted is the red copper that purity is greater than 99.98%.The outer wrapped two-sided synthetic mica tape 2 successively of oxygen-free copper conductor 1, extrude 3, the 105 DEG C of ultraviolet light irradiation cross-linking halogen-free and low-smoke flame-retardant polyolefins insulation 4 of 105 DEG C of ultraviolet light irradiation cross-linking polyethylene insulations.The Thickness Ratio of 105 DEG C of ultraviolet light irradiation cross-linking polyethylene insulations, 105 DEG C of ultraviolet light irradiation cross-linking halogen-free and low-smoke flame-retardant polyolefin insulation is 1:2.
Wherein oxygen-free copper conductor 1 is conductor, and electric property is remarkable, and conductance is high, and two-sided synthetic mica tape 2 serves as the fireprotection layer of whole cable, while raising cable fire ability, also improves the insulating properties of cable.Two-sided synthetic mica tape 2 and 105 DEG C of ultraviolet light irradiation cross-linking polyethylene insulations, 3,105 DEG C of ultraviolet light irradiation cross-linking halogen-free and low-smoke flame-retardant polyolefins insulate 4 shared insulators, strengthen the integral insulation performance of cable.3, the 105 DEG C of ultraviolet light irradiation cross-linking halogen-free and low-smoke flame-retardant polyolefin insulation 4 of described 105 DEG C of ultraviolet light irradiation cross-linking polyethylene insulations have insulation and sheath effect concurrently, guarantee that cable electrical performance, resistance to ag(e)ing are excellent, fire-retardant, fire resistance is high, cable long service life, low smoke, zero halogen environmental protection.
A kind of ultraviolet light cross-linking high life low smoke, zero halogen fire-resistant environment-friendly type electric wire electric property that the present embodiment provides is superior, and fire resistance is high, cable long service life, low smoke, zero halogen environmental protection.Without in flame calcination situation, the outer Trinitarian structural design of conductor, guarantee that electric property is safe and reliable, leakproof, cable long service life, in flame calcination situation, cable fire ability rating is higher than normal refractory electric wire, and combustion product low smoke, zero halogen, really realize the environmental protection high-quality cable of cable high life, high-performance, high fire resistant flame retardant.
Due to the existence of Trinity insulator, make cable life can accomplish to be greater than 70 years, break away from the present situation that the electric wire life-span is less than House Property, for building design units provides more powerful effective premium quality product to support.Cable itself is fire-retardant and fire-resistant, effectively avoiding electric wire as the flame propagation body under fire condition, and be user's continued power within a certain period of time, is the escape of the incident area Field Force of breaking out of fire, strive for the more time, for user's personal safety and public property escort safely.
