Abstract
The utility model discloses an energy-saving steel core/high-strength aluminum alloy molded wire-stranded insulated cable. The energy-saving steel core/high-strength aluminum alloy molded wire-stranded insulated cable comprises steel cores and at least two layers and at most four layers of aluminum alloy molded wire layers which are arranged at the exterior of the steel cores; the aluminum alloy molded wire layers are arranged at the exterior of the steel cores in a manner that a plurality of aluminum alloy molded wires are circumferentially arranged around the steel cores along the radial direction of the steel cores, and are concentrically stranded together with the steel cores; the exterior of the aluminum alloy molded wire layers is successively provided with a shielding layer and an insulating layer; the thickness of the shielding layer is in a range of 0.3 to 0.5 cm; and the thickness of the insulating layer is in a range of 0.7 to 1.2 cm. Compared with an ordinary cable, the energy-saving steel core/high-strength aluminum alloy molded wire-stranded insulated cable is advantageous in that the electric conductivity of the energy-saving high-strength aluminum alloy molded wires is 55% IACS and is increased by 2.5% IACS compared with that of ordinary high-strength aluminum alloy wires; and the molded wires are closely stranded, such that the effective power transmission section of the energy-saving steel core/high-strength aluminum alloy molded wire-stranded insulated cable can be increased, and the transmission capacity of the energy-saving steel core/high-strength aluminum alloy molded wire-stranded insulated cable can be improved.
Description
Technical field
The utility model relates to a kind of energy-conservation steel core high-strength aluminum alloy 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, 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-conservation steel core high-strength aluminum alloy 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-conservation steel core high-strength aluminum alloy molded lines strand insulated cable, comprise steel core and be located at steel core outer at least 2 layers, 4 layers aluminium alloy molded lines layer at the most, described aluminium alloy molded lines layer radially is circle-shaped encirclement by some aluminium alloy molded lines along described steel core and is arranged on the steel core, and twists together with described steel core concentric-ring pattern; Described aluminium alloy molded lines layer skin also is provided with screen and insulating barrier successively; Described shielding thickness is 0.3-0.5cm, and described thickness of insulating layer is 0.7-1.2cm.
Preferably, the adjacent layer of described aluminium alloy molded lines layer strand is on the contrary, and outermost layer twists to being dextrad.
Preferably, the contact-making surface of adjacent aluminium alloy molded lines is plane or zigzag face in the described aluminium alloy molded lines layer.
Preferably, described steel core is made of a galvanized steel wire or is that a galvanized steel wire and Duo Gen twist the multilayer heart yearn that the galvanized steel wire in this galvanized steel wire periphery constitutes with one heart.
Preferably, described aluminium alloy molded lines is T shape aluminium alloy molded lines or Z-shaped aluminium alloy molded lines.
The beneficial effects of the utility model: energy-conservation steel core high-strength aluminum alloy molded lines strand insulated cable is compared common cable, and the peripheral multi-layer energy-saving high-strength aluminum alloy molded lines conductance that coats is 55%IACS, compares the rolled products of ordinary high-strength aluminium alloy wire and improves 2.5%IACS; 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-conservation steel core high-strength aluminum alloy molded lines strand insulated cable is outstanding, compares common steel core high-strength aluminum alloy twisted wire insulated cable and reduces line loss more than 3.5%.
