In developed countries, AAAC conductor wire and cable industry research applications have more than 90 years, but have made significant technological advances and widely used, but it is in the 1960s - after 70 years, AAAC conductor brands and varieties developed gradually diversify and began to put into application in many fields.
Aluminum used in overhead transmission lines in
High-strength aluminum alloy wire: the superiority that high tensile strength, tensile load for the next big project conditions, such as large span engineering and high wind loads, power transmission line icing in sections. But its relatively low conductivity, line power loss is relatively large, so most of the regional section line use.
The strength of AAAC conductor wire: Tensile strength is 1.5 times of hard aluminum conductivity aluminum and hard close, and far greater than the elongation of hard aluminum, with excellent mechanical and electrical overall performance. If it were, will have a good technical and economic performance.
Heat-resistant AAAC conductor wire: Tensile strength and hard aluminum same conductivity close (except for high-strength heat-resistant aaac conductor outer), the main advantage is at 150 ℃ and the operating temperature can be maintained over the long-term tensile strength of more than 90%. Mainly used to improve the transmission capacity of the line leaving the operating temperature increase of line project. But increasing the operating temperature while increasing the line power consumption, the higher the temperature the greater the line loss, which is mainly used really need to increase the transmission capacity, length, and not too long lines, especially the line renovation project.
Current overview of aluminum cables
Profile: 60 years since the last century, the AAAC conductor(with AA8030 as the representative) power cables began used in North America, mainly for building low-voltage distribution systems, has been nearly 60 years of manufacturing applications practice, many projects, in the long run, prove that the product is safe and reliable.
Applications: more suitable for use in the building cable laying. Armored structure cable has flame retardant properties, non-armored cable with flame retardant jacket can be directly used for flame retardant requirements of buildings, such as office buildings, hotels, shopping centers, and engineering lighting, power, and another feeder line electrical equipment. In view of the application in the building cable design specifications and use of high-rise building fire safety considerations and the electrical system of choice for cable, aaac conductor should not be used as a refractory grade cable, at least the need for further research to determine.
Aluminum use in other cable products
Overview: In recent years, with the development of the automotive industry's increasingly fierce market competition and lightweight technology, foreign auto companies began to develop part of small-volume applications and lightweight automotive wiring harness products. Compared with conventional copper conductor cable, lightweight design of aluminum and AAAC conductor wire products automotive technology has obvious advantages: low cost, lightweight, especially for electricity as the primary power source for electric cars class cars.
