The energy-saving intermediate strength aluminium alloy wire layers comprise a plurality of aluminium alloy wires, and the aluminium alloy wires surround and are arranged on the glass fiber core along a radial direction of the glass fiber core in a circumference manner. The aluminium alloy wires strand with the glass fiber core in a concentric circle manner. A shielding layer and an insulating layer are disposed outside the energy-saving intermediate strength aluminium alloy wire layers in sequence. Thickness of the shielding layer is 0.21-0.31 cm, and thickness of the insulating layer is 0.4-0.7 cm. Electric conductivity of the plurality of layers of energy-saving intermediate strength aluminium alloy wires wrapping outside the insulated cable is 60% IACS, and compared with an ordinary intermediate strength aluminium alloy wires, the electric conductivity improves 2% IACS. The glass fiber core has high tensile strength, reaching higher than 2100 MP. Power transmission cross section is effectively increased, and transmission capacity is improved.
Description
Technical field
The utility model relates to strength aluminium alloy molded lines strand insulated cable in a kind of energy-saving glass fiber core.
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, as the wherein decision-making of transmission line capability, mainly solve from two approach, the one, transmission voltage wherein, the 2nd, transmission current wherein, under the certain prerequisite of voltage, transmission current density wherein, namely wherein the transmission line capability of lead unit are just show 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 strength aluminium alloy molded lines strand insulated cable in a kind of energy-saving glass fiber core at the defective that prior art exists.
The utility model for achieving the above object, adopt following technical scheme: strength aluminium alloy molded lines strand insulated cable in a kind of energy-saving glass fiber core, comprise fiber glass core and be located at fiber glass core outer at least 2 layers, strength aluminium alloy molded lines layer in 4 layers energy-conservation at the most, described energy-conservation middle strength aluminium alloy 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 middle strength aluminium alloy molded lines layer skin also is provided with screen and insulating barrier successively; Described shielding thickness is 0.21-0.31cm, and described thickness of insulating layer is 0.4-0.7cm.
