Abstract
The utility model discloses an irradiation crosslinking chlorinated polyethylene (CPE) insulating flexible cable which comprises a cable core, wherein the cable core is formed by a plurality of wire cores in an intertwisting mode. Wire cores comprise tin plated copper wire intertwisted conductors located in the middle, conductor isolating layers and CPE insulating layers, wherein the conductor isolating layers and the CPE insulating layers are arranged outside the tin plated copper wire intertwisted conductors in sequence. Gaps in the cable core are filled with fillers, cable core isolating layers and outer protecting layers, wherein the cable core isolating layers and the outer protecting layers are arranged outside the cable cores in sequence. According to the irradiation crosslinking CPE insulating flexible cable, the structure can satisfy the requirements of usage conditions of high electrical properties, and the requirements of oil resistance, ozone resistance, climate resistance, heat resistance, fire resistance and high strength properties can be achieved. Meanwhile, the irradiation crosslinking CPE insulating flexible cable has the functions of energy conservation and environmental protection.
Description
Technical field:
The utility model relates to a kind of cross-linking radiation chlorinated polythylene insulating flexible cable, and 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.
The utility model content
The utility model technical problem to be solved 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 beneficial effect of the utility model is: the structure of the utility model 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 the cross-sectional view of the utility model.
Embodiment
As shown in Figure 1; A kind of cross-linking radiation chlorinated polythylene insulating flexible cable of the utility model; 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 the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
