Abstract
The utility model discloses an aluminum alloy conductor compensating cable used for a nuclear power station. The aluminum alloy conductor compensating cable used for the nuclear power station is characterized in that five insulating wire cores are twisted into a cable, an outer polyester belt is lapped on the outside of the cable core, a metal total shielding layer is braided on the outside of the outer polyester belt, and a halogen-free low-smoke flame-retardant jacket is lapped on the outside of the metal total shielding layer; each insulating core is composed of conductor wire cores, a crosslinking halogen free insulating layer, an inner polyester belt and a branch shielding layer; each conductor wire core is formed by extruding an inner insulating layer on the outside of an aluminum alloy conductor, and the crosslinking halogen free insulating layer is extruded on the outsides of the conductor wire cores; the inner polyester belt is arranged on the outside of the crosslinking halogen free insulating layer, and the branch shielding layer is braided on the outside of the inner polyester belt. The aluminum alloy conductor compensating cable used for the nuclear power station of the utility model enables the production cost of an enterprise to be reduced, and has better extensibility and inverse elasticity by being compared with a copper conductor cable.
Description
Technical field
The utility model belongs to the electric wire field, is specifically related to a kind of used in nuclear power station aluminium alloy conductor compensating cable.
Background technology
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.
Along with China's rapid economy development, increasing to the requirement of cable in all trades and professions, also more and more higher to the performance requirement of cable.
Traditional used in nuclear power station compensating cable cable uses copper conductor more, fewer and feweri along with copper ore resource, and the price of copper raw material is also more and more higher, and this has strengthened the production cost of enterprise undoubtedly.
The utility model content
The utility model provides a kind of used in nuclear power station aluminium alloy conductor compensating cable, not only can reduce the production cost of enterprise, compare with the copper conductor cable simultaneously have better extensibility, bounce-back property.
Scheme of the present utility model is as follows: a kind of used in nuclear power station aluminium alloy conductor compensating cable, five thoroughly do away with the stranded stranding of edge core, the outer wrapped outer polyester band of cable core, the outer total screen of braided metal of described outer polyester band, the outer wrapped LSOH anti-flaming sheath of the total screen of described metal; Insulated wire cores is made of conductor thread core, crosslinked halogen-free insulating barrier, interior polyester band, sub-shield, described conductor thread core extrudes inner insulating layer outward by aluminium alloy conductor and constitutes, described conductor thread core extrudes the crosslinked halogen-free insulating barrier outward, the crosslinked halogen-free insulating barrier arranges interior polyester band outward, and interior polyester band weaves sub-shield outward; On the polyester band drainage thread is set in described.
Described aluminium alloy conductor is rare earth high ferro aluminium alloy conductor.
Described conductor thread core is two.
Described aluminium alloy conductor cross-sectional area is 3～80mm2.
The utility model is replaced by aluminium alloy conductor with traditional copper conductor, can alleviate cable weight, reduces installation cost, and the wearing and tearing of minimizing equipment and cable make installment work lighter; Satisfying under the prerequisite of equal electric property, the weight of using the aluminium alloy cable is half of copper core cable, and its cross section is 1.1 ~ 1.25 times of traditional copper core cable, and price is than traditional copper core cable low 30% ~ 50%.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of used in nuclear power station aluminium alloy conductor compensating cable, five thoroughly do away with the stranded stranding of edge core, the outer wrapped outer polyester band 1 of cable core, the outer total screen 2 of 1 braided metal of described outer polyester band, the total screen 2 outer wrapped LSOH anti-flaming sheaths 3 of described metal; Insulated wire cores is made of conductor thread core, crosslinked halogen-free insulating barrier 4, interior polyester band 5, sub-shield 6, described conductor thread core constitutes by extruding inner insulating layer 8 outside the aluminium alloy conductor 7, described conductor thread core extrudes crosslinked halogen-free insulating barrier 4 outward, crosslinked halogen-free insulating barrier 4 arranges interior polyester band 5, interior polyester band 5 outer braiding sub-shields 6; On the polyester band drainage thread 9 is set in described.
In concrete the enforcement, described aluminium alloy conductor 7 is rare earth high ferro aluminium alloy conductor; Described conductor thread core is two; Described aluminium alloy conductor 7 cross-sectional areas are 3～80mm2.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
