Description
Technical field
The utility model relates to a kind of energy-saving glass fiber core high-strength aluminum alloy twisted wire insulated cable.
Background technology
Develop rapidly along with national economy, China's power industry has had the progress of advancing by leaps and bounds, strategic plan according to " transferring electricity from the west to the east, north and south supplies mutually, national network ", at a distance, the construction of large capacity transmission circuit is imperative, also have higher requirement to overhead power transmission conducting wire simultaneously, as the decision-making that improves transmission line capability, mainly solve from two approach, the one, improve transmission voltage, the 2nd, improve transmission current, under the certain prerequisite of voltage, improve transmission current density, the transmission line capability that namely improves the lead unit are is very important with regard to what show.At present, the employed lead of China's overhead transmission line still is traditional steel reinforced aluminium conductor basically and since its heat resistance relatively a little less than, so the transmission line capability of circuit is subjected to certain restriction.
The effect of power construction in the national economic development is increasing, and the development of power industry is concerning overall people's exhibition of national economy.Along with this situation, a new step has been stepped up in the power construction of China, has also become the task of top priority and the research and development of pushing forward new technology and new product comprehensively substitute existing product.Aluminium alloy core aluminium stranded conductor line is littler than same specification ordinary steel core aluminum stranded wire resistance, transmission line capability is big, in light weight, intensity is high, based on these advantages, the use amount of aluminium alloy conductor increases year by year.
The utility model content
The utility model purpose is to provide a kind of energy-saving glass fiber core high-strength aluminum alloy twisted wire insulated cable at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object: a kind of energy-saving glass fiber core high-strength aluminum alloy twisted wire insulated cable comprises fiber glass core and the energy saving high degree aluminium alloy wire layer of concentric strand outside fiber glass core; Described energy saving high degree aluminium alloy wire layer is enclosed with screen and insulating barrier outward successively; Described shielding thickness is 0.4-0.6cm, and described thickness of insulating layer is 0.8-1.5cm.
Preferably, described fiber glass core is by a fiber glass core bar construction, and its diameter is 5-11mm.
Preferably, described energy saving high degree aluminium alloy wire layer comprises many aluminium alloy single lines of the same size.
Preferably, the adjacent layer of described energy saving high degree aluminium alloy wire layer strand is on the contrary, and outermost layer twists to being dextrad.
Preferably, described energy saving high degree aluminium alloy wire layer mostly is four layers most.
The beneficial effects of the utility model: energy-saving glass fiber core high-strength aluminum alloy twisted wire insulated cable is compared common cable, the conductance of aluminium alloy single line is 55%IACS in the peripheral multi-layer energy-saving high-strength aluminum alloy line layer that coats, and compares the rolled products of ordinary high-strength aluminium alloy wire and improves 2.5%IACS.Fiber glass core tensile strength is big, reaches more than the 2100MP, and the energy-saving effect of overall energy-saving glass fiber core high-strength aluminum alloy twisted wire insulated cable is outstanding, compares simple glass fibre core high-strength aluminum alloy twisted wire insulated cable and reduces line loss more than 3.5%.Be particularly suitable for the line construction of large span area (mountain area, rivers).
