Abstract
The utility model discloses an energy saving glass fiber core aluminum strand insulation cable comprising glass fiber cores and at least 2, at most 4 layers of energy saving aluminum stranded conductors, which are disposed on outer sides of the glass fiber cores. The layers of aluminum stranded conductors are formed by arranging a plurality of aluminum stranded conductors on the glass fiber cores along radial directions of the glass fiber cores in a peripherally wrapped manner and intertwisting the aluminum stranded conductors with the steel cores concentrically. Outer sides of the layers of energy saving aluminum stranded conductors are sequentially provided with a shielding layer and an insulation layer. The thickness of the shielding layer is in a range from 0.1 to 0.2cm, and the thickness of the insulation layer is in a range from 0.2 to 0.3cm. Compared to the common intermediate strength aluminum alloy cables, the conductivity of each of the multi-layer energy saving intermediate strength aluminum stranded conductors is 63%IACS, which is 2% IACS more than that of the common intermediate strength aluminum alloy cables; the tensile strength of the glass fiber cores is large, and can reach more than 2100MP; the power transmission cross section can be effectively increased, and the transmission capacity can be improved.
Description
Technical field
The utility model relates to a kind of energy-saving glass fiber core aluminium molded lines strand 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, requirement in simultaneously also having proposed more to overhead power transmission conducting wire, decision-making as transmission line capability in carrying, mainly solve from two approach, the one, carry middle transmission voltage, the 2nd, carry middle transmission current, under the certain prerequisite of voltage, transmission current density in carrying, what the transmission line capability of lead unit are just showed in namely carrying is very important.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 aluminium molded lines strand insulated cable at the defective that prior art exists.
The utility model for achieving the above object, adopt following technical scheme: a kind of energy-saving glass fiber core aluminium molded lines strand insulated cable, comprise fiber glass core and be located at fiber glass core outer at least 2 layers, 4 layers energy-conservation aluminium molded lines layer at the most, described energy-conservation aluminium molded lines layer radially is circle-shaped encirclement by some aluminium molded lines along described fiber glass core and is arranged on the fiber glass core, and twists together with described fiber glass core concentric-ring pattern; Described energy-conservation aluminium molded lines layer skin also is provided with screen and insulating barrier successively; Described shielding thickness is 0.1-0.2cm, and described thickness of insulating layer is 0.2-0.3cm.
Preferably, the adjacent layer of described energy-conservation aluminium molded lines layer strand is on the contrary, and the outermost layer strand is to for to the right.
Preferably, the contact-making surface of adjacent aluminium molded lines is plane or zigzag face in the described energy-conservation aluminium molded lines layer.
Preferably, described fiber glass core is by a fiber glass core bar construction, and its diameter is 5-11mm.
Preferably, described aluminium molded lines is T shape aluminium molded lines or Z-shaped aluminium molded lines.
The beneficial effects of the utility model: energy-saving glass fiber core aluminium molded lines strand insulated cable is compared common cable, and the conductance of the peripheral multi-layer energy-saving aluminium molded lines that coats is 63%IACS, compares common aluminum steel and improves 2%IACS; Fiber glass core tensile strength is big, reaches more than the 2100MP, and molded lines is stranded closely, and the activity coefficient height can effectively increase the transmission of electricity cross section, promotes transmission capacity.The energy-saving effect of overall energy-saving glass fiber core aluminium molded lines strand insulated cable is outstanding, compares simple glass fibre core aluminium stranded conductor insulated cable and reduces line loss more than 3.28%, is particularly suitable for the line construction of large span area (mountain area, rivers).
