Abstract
The utility model discloses a copper-clad aluminum conductor installation electric wire, comprising a conductor. The conductor is formed by wrapping an insulating layer and an outer conductor on the outside of an inner conductor orderly, the inner conductor is formed by twisting a plurality of aluminum wires taking an elastic rope as the center, and the cross section of the elastic rope is fusiform; a steel wire of which the cross section is elliptic is arranged in the elastic rope, the outer conductor is wrapped with a pure copper, and a sheath layer is wrapped on the outside of the conductor. The copper-clad aluminum conductor installation electric wire of the utility model is good in corrosion resistance, small in conductor contact resistance, light in weight and soft in wire quality, is anti-rat and anti-termite, has a good weldability, and enables the service life of the electric wire to be prolonged.
Description
Technical field:
The utility model relates to technical field of electric wires and cables, relates in particular to a kind of copper clad aluminum conductor electric wire is installed.
Background technology:
Current nonferrous metal price rises suddenly and sharply, and the copper conductor cost accounts for electric wire, more than 90% of cable raw material total cost.In order to guarantee to satisfy the technical indicator of electric wire, cable copper conductor, can reduce electric wire, cable cost significantly again, according to the market demand, the equipment of the existing factory of utilization, detecting instrument etc. have been developed the copper clad aluminum conductor electric wire.
Electric wire corrosion resistance in the past is relatively poor, the compressive property of conductor and tensile property can not satisfy the real work demand, causes shorten the useful life of electric wire.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of copper clad aluminum conductor electric wire is installed, and access node structure simplicity of design is reasonable, has prolonged the useful life of electric wire effectively.
The technical scheme of the utility model is following:
Copper clad aluminum conductor is installed electric wire; Comprise conductor, it is characterized in that: described conductor by inner wire outward successively wrap insulate layer, outer conductor constitute, it is that central beam strand constitutes with the elastic threads that inner wire adopts several aluminum steels; The cross section of elastic threads is a fusiformis; Being provided with the cross section in the elastic threads is oval-shaped steel wire, and described outer conductor adopts the fine copper bag to attach formation, and conductor is wrapped with restrictive coating.
Described copper clad aluminum conductor is installed electric wire, it is characterized in that: it is nylon that described restrictive coating adopts material.
The utility model has the advantages that:
1, the utlity model has good anti-corrosion, the conductor contact resistance is little.Aluminum ratio copper is perishable under the normal condition, but because the aluminium in the copper cover aluminum is coated by copper fully, has improved aluminium conductor and be prone to oxidation, weakness that contact resistance is big.
Therefore 2, the utlity model has good weldability, copper-clad aluminum conductor has with the same weldability of fine copper because its surface has coated one deck fine copper, avoided aluminium cable in long-term use because of corrosion.Damage or because of pressing bad and Wuxi welding causes conductor and binding post loose contact, the hidden danger that causes wire end to burn.
3, the utility model is in light weight, line matter soft, termite-resistant rodent-resistant is convenient to install.
4, the utility model copper clad aluminum conductor is compared with pure cu conductor, and except that the advantage that possesses copper conductor, under the conductor DC resistance condition identical with the pure cu conductor D.C. resistance, its AC resistance is littler than copper, and ampacity is than the big 2%-5% of copper.Technical indicators such as its electric wire line loss, temperature rise are better than copper conductor cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Copper clad aluminum conductor is installed electric wire, comprises conductor, and conductor is by wrap insulate layer 2, outer conductor 3 constitute successively outside the inner wire 1; It is that the central beam strand constitutes with elastic threads 5 that inner wire 1 adopts several aluminum steels 4, and the cross section of elastic threads 5 is a fusiformis, effectively raises the extraneous compressive property of wire pair; Being provided with the cross section in the elastic threads 5 is oval-shaped steel wire 6; Improved electric wire tensile property in use, outer conductor 3 adopts the fine copper bag to attach formation, and conductor is wrapped with restrictive coating 7.
It is nylon that restrictive coating 7 adopts material.
Claims (2)
1. a copper clad aluminum conductor is installed electric wire; Comprise conductor, it is characterized in that: described conductor by inner wire outward successively wrap insulate layer, outer conductor constitute, it is that central beam strand constitutes with the elastic threads that inner wire adopts several aluminum steels; The cross section of elastic threads is a fusiformis; Being provided with the cross section in the elastic threads is oval-shaped steel wire, and described outer conductor adopts the fine copper bag to attach formation, and conductor is wrapped with restrictive coating.
2. copper clad aluminum conductor according to claim 1 is installed electric wire, it is characterized in that: it is nylon that described restrictive coating adopts material.
