Abstract
The invention discloses an irradiation crosslinked chlorinated polyethylene insulating flexible cable, which comprises a cable core formed by stranding a plurality of wire cores. Each wire core comprises a middle tinned wire stranded conductor and further comprises a conductor isolation layer and a chlorinated polyethylene insulating layer sequentially arranged outside the conductor. Filler is filled in gaps of the cable core, and a cable core isolation layer and a sheath layer are sequentially arranged outside the cable core. The irradiation crosslinked chlorinated polyethylene insulating flexible cable structurally meets the requirements of utilization conditions on high electrical performance, oil resistance, ozone resistance, weather resistance, heat resistance, flame retardation and high strength performance, and has the advantages of energy saving and environmental protection.
Description
?
Technical field:
The present invention relates to a kind of cross-linking radiation chlorinated polythylene insulating flexible cable, rated voltage 450/750V is applicable to the occasion that the indoor introducing of building, machinery equipment, power supply, control and inside electric, electronic equipment are connected.
Technical background:
The production of the present rubber cable of China is main, seriously polluted with natural gum, neoprene, chlorosulfonated polyethylene mainly, and the outmoded backwardness of production technology, energy consumption are big, and cost is high, and in use quality defects often also influences the raising of rubber cable technical merit.Haloflex (CPE) has more comprehensive technical performance, like good anti-flammability and oil resistance, and higher physical and mechanical properties (being mechanical property); Good heat-proof aging, anti-ozone, weather-resistant property; Electrical property and good performance of technical process preferably, general rubber tooling can use, and sizing material is difficult for taking place incipient scorch; The CPE raw material storage several years also undergoes no deterioration, and has better also can the depositing of sizing material storage condition of vulcanizing agent to never degenerate in 1 ~ 2 year.Made insulation or sheath with natural-butadiene-styrene rubber, its highest long-term work temperature only allows 60 ~ 65 ℃ in the past; If use CPE to make general low-voltage insulation, its highest long-term work temperature can reach 90 ℃.
CPE adopts electron accelerator irradiation crosslinked; Because without peroxide cross-linking agent, so electrical property is good, specific insulation is higher 100 times than peroxide crosslinking; The insulation temperature resistant grade can reach 125 ℃; The maximum operating temperature of sheath reaches 90 ℃, possesses simultaneously performances such as good heat-proof aging, oil resistant, anti-ozone, weather, heat-resisting, fire-retardant and high strength again, compares with traditional rubber cable sulfuration cylinder sulfuration or steam continuous vulcanization technology; Technology is simple, production cost is low, and energy-conserving and environment-protective.
Summary of the invention
Technical problem to be solved by this invention provides the cross-linking radiation chlorinated polythylene insulating and the sheath rubber flexible cable of a kind of thermal endurance and high comprehensive performance.
A kind of cross-linking radiation chlorinated polythylene insulating flexible cable; This cable comprises cable core; Said cable core forms by the several wire core is stranded; Said core comprises middle tinned wird stranded conductor and is successively set on this conductor outer conductor isolation layer and chlorinated polythylene insulating layer that the gap in cable core is filled with filler, outside cable core, sets gradually cable core separator and outer jacket.
The invention has the beneficial effects as follows: structure of the present invention satisfies service condition to high electrical property, and the requirement of oil resistant, anti-ozone, weather, heat-resisting, fire-retardant and high-intensity performance has the function of energy-conserving and environment-protective simultaneously.
Description of drawings
Fig. 1 is a cross-sectional view of the present invention.
Embodiment
As shown in Figure 1; A kind of cross-linking radiation chlorinated polythylene insulating flexible cable of the present invention; This cable comprises cable core; Said cable core forms by the several wire core is stranded, and said core comprises middle tinned wird stranded conductor 1 and be successively set on this conductor outer conductor isolation layer 2 and chlorinated polythylene insulating layer 3 that the gap in cable core is filled with filler 4, outside cable core, sets gradually cable core separator 5 and outer jacket 6
The conductor manufacturing approach: conductor adopts stranded the forming of zinc-plated anaerobic copper cash, has good electric property and decay resistance.
The insulation manufacturing approach: but adopt the IXPE band wrapped outside conductor as separator, separator extrudes the cross-linking radiation chlorinated polythylene insulating outward.
Method for manufacturing protective sleeve: fill and adopt the PP gasket for packing, but the outer wrapped one deck IXPE band of the cable core of cable is as separator, after cable core extrudes the cross-linking radiation chlorinated polyethylene sheath outward, through the crosslinked finished product of processing of electron accelerator irradiation.Make the insulation temperature resistant grade reach 125 ℃, the maximum operating temperature of sheath reaches 90 ℃, specific insulation>=1 * 10 of insulating under 20 ℃ of conditions
15Ω m.
The above only is a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
