Abstract
The utility model discloses an aluminum alloy MC cable. An aluminum alloy MC cable, includes: aluminum alloy conductor, nylon insulating layer, polypropylene sticky tape are around covering and chain armor aluminum alloy area restrictive coating. The utility model discloses a nylon is insulating to replace traditional polyethylene to allow operating temperature 90 DEG C requirement for a long time as insulating layer, its finished cable adaptation. Develop by oneself armor aluminum alloy area and replace traditional aluminium strip, light in weight, with low costs, easily lay and installation, anti creep and extensibility all very good, and be adapted to use under strong chloride, salt acid -base and other harmful chemical's environment.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of aluminium alloy MC cable.
Background technology
Electric wire, cable are the important industries of China's capital construction, and in recent years, domestic market competition progressively develops into competition in the international market.Because China's copper resource is congenital more rare, the demand and supply contraction highlights, and adds the shortcomings such as copper core cable construction and installation difficulty is large, installation cost is high, oxidizable; Therefore people are also day by day surging for the cry of " aluminium is for copper " cable.The cable of European and American areas 90% is all aluminium alloy cable, but not clearly in the present situation of China's " aluminium is for copper ", along with national grid transformation, the enforcement of engineering and the iterative method of Urbanization Construction, National Energy Board has issued relevant aluminium alloy cable standard in 2015 04 month, has numerous electric wire enterprise self-determining to research and develop aluminium alloy cable to facilitate the main force becoming power construction with " aluminium is for copper " when the time comes.
According to new standard " NB/T42051-2015 rated voltage 06/1KV aluminium alloy conductor cross-linked polyethylene insulated cable " 4.2 insulation compound requirements, during normal operation, conductor maximum temperature is 90 DEG C, and existing aluminium alloy MC cable cannot meet this standard-required.Current China aluminium alloy MC the coat layer of power cable is aluminium strip armouring restrictive coating, and heat dispersion is bad and cost is high.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of lightweight, cost is low, perfect heat-dissipating, easily lay and install, creep resistant and extensibility all extraordinary " chain armouring aluminum alloy strip oversheath MC cable ", appropriate cable new standard conductor allows working temperature 90 DEG C of requirements for a long time, and can adapt to use under the environment of strong chloride, salt soda acid and other harmful chemicals.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of aluminium alloy MC cable, from the inside to the outside, comprises aluminium alloy conductor 1, nylon insulating barrier 11, polypropylene tape lapping layer 3 and chain armouring aluminum alloy strip restrictive coating 4; Described nylon insulating barrier 11 special-purpose high temperature extruder, is coated on aluminium alloy conductor 1 outer after extruding; Described polypropylene tape lapping layer 3 is arranged on the skin of nylon insulating barrier 11, and wrapped Duplication is arranged between 10%-15%; Described chain armouring aluminum alloy strip restrictive coating 4 is arranged on the skin of polypropylene tape lapping layer 3; Wherein the width of this chain armouring aluminum alloy strip is arranged between 9.5mm ~ 19.0mm, and thickness is arranged between 0.5mm ~ 0.75mm, conductance >=30%.
Cable weight of the present utility model is light, cost is low, easily lay and install, creep resistant and extensibility all very good.The utility model appropriate cable new standard conductor allows working temperature 90 DEG C of requirements for a long time, adapts to use under the environment of strong chloride, salt soda acid and other harmful chemicals.Cable of the present utility model is prepared material and is easy to buy, cost-saving, directly can lay, improve the fail safe that electrical equipment uses in installation exercise, can replace expensive " copper core cable " at various environment.
" the chain armouring aluminum alloy strip oversheath MC cable " of the utility model research and development, this cable ratio " copper core cable " can alleviate the weight of 50%, reduce installation cost, make installment work more light, the more important thing is the problem balancing China's copper scarcity of resources and the demand and supply contraction.
Accompanying drawing explanation
Fig. 1 is perspective cut-away structural representation of the present utility model, and Fig. 2 is cross section cut-away illustration of the present utility model.
In the accompanying drawings: 1, aluminium alloy conductor; 11, nylon insulating barrier; 3, polypropylene tape lapping layer; 4, chain armouring aluminum alloy strip restrictive coating.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in drawings, a kind of aluminium alloy MC cable, from the inside to the outside, comprises aluminium alloy conductor 1, nylon insulating barrier 11, polypropylene tape lapping layer 3 and chain armouring aluminum alloy strip restrictive coating 4; Described nylon insulating barrier 11, through special-purpose high temperature extruder, is coated on aluminium alloy conductor 1 outer after extruding; Described polypropylene tape lapping layer 3 is arranged on the skin of nylon insulating barrier 11, and wrapped Duplication arranges between 10%-15%; Described chain armouring aluminum alloy strip restrictive coating 4 is arranged on the skin of polypropylene tape lapping layer 3; Wherein the width of this chain armouring aluminum alloy strip is set between 9.5mm ~ 19.0mm, and thickness is set between 0.5mm ~ 0.75mm, conductance >=30%.
The utility model adopts nylon insulating barrier 11 to replace crosslinked polyetylene insulated layer, and appropriate cable new standard conductor allows working temperature 90 DEG C of requirements for a long time, adapts to use under the environment of strong chloride, salt soda acid and other harmful chemicals.Cable of the present utility model is prepared material and is easy to buy, cost-saving, directly can lay, improve the fail safe that electrical equipment uses in installation exercise, can replace expensive " copper core cable " at various environment.
" the chain armouring aluminum alloy strip oversheath MC cable " of the utility model research and development, lightweight, cost is low, easily lay and install, creep resistant and extensibility all very good, this cable ratio " copper core cable " can alleviate the weight of 50%, reduce installation cost, make installment work more light, the more important thing is the problem balancing China's copper scarcity of resources and the demand and supply contraction.
Above-described embodiment limits the utility model never in any form, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection range of the present utility model.
