Abstract
The utility model relates to parallel cluster electric wires, which comprises parallel insulation conductors A, B, C, D provided with an insulation material layer, and is characterized in that the insulation conductor A and the insulation conductor B, the insulation conductor A and the insulation conductor C, the insulation conductor B and the insulation conductor D are respectively connected through insulation belts. Compared with the prior art, because the distribution of the magnetic field and the electric field therearound is changed, the reactance is reduced, the susceptance is increased, and loss of voltage along the line is evidently reduced; the occurrence of electricity stealing and leakage can be effectively prevented in the aspect of technical measures; the iron core in the conductor A increases the mechanical strength and the pulling resistance of the conductor line; the electric wire also has features of little occupation space, low synthetic cost during stringing, and little susceptibility to environmental factors.
Description
Technical field
The utility model belongs to the bundled insulated conductors field, the parallel insulation Bundling conducting wire of the four-core that particularly a kind of zero line is a steel reinforced aluminium conductor.
Background technology
The low-voltage distribution wire rod has realized that the distribution transformer low-pressure side is to user's electric power transfer in the low voltage network.At present, both at home and abroad the main wire rod of low-voltage distributing line has following several types: 1. plain conductor generally is conductor with aluminium, uses with aluminium stranded conductor or steel reinforced aluminium conductor form.Before China's upgrade of rural power grids, this lead of the most of employing of 0.4kV side supply line.2. with France the stranded formula structure insulation Bundling conducting wire that more than 80 country's experiments of representative are carried out.The use of this structure lead makes step down side arrive user's the whole insulatings of supply line, has reduced electric shock accidents, has improved the fail safe of electricity consumption.3. China brought into use the four-core insulated conductor of parallel construction in 1997, and wherein three cores are live wire, and an other core is a zero line.This wire rod also has the advantage that production technology is simple, reduce lead electrical distance, minimizing power loss except the advantage with stranded formula structure bundled insulated conductors.
In use there is following problem respectively in above-mentioned several wire rod: 1. plain conductor can not effectively prevent stealing, leaky, causes the accident of human electric shock easily, and occupies certain circuit corridor, space, and frequent and street greening clashes.2. stranded formula structure bundled insulated conductors production process is many, compares with the Bundling conducting wire of parallel construction under identical electrical distance, and effectively conductor length increases.3. the Bundling conducting wire of parallel construction all adopts aluminum core material, because the deadweight of four leads and stretching resistance restriction, line span is limited.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of four-core parallel insulation Bundling conducting wire, and is simple in structure, can effectively prevent stealing, electric leakage, and the line holding space is little, is not subject to the external environment factor affecting, and reactance is little, and susceptance is big, and the line voltage distribution loss is few.Compare with the Bundling conducting wire of the parallel construction that all adopts aluminium core or copper core material, stretching resistance effectively improves.
Technical solution of the present utility model is as follows: comprise the parallel insulated electric conductor A, B, C, the D that are provided with insulation material layer, it is characterized in that: insulated electric conductor A links to each other by insulating tape respectively with insulated electric conductor D with insulated electric conductor C, insulated electric conductor B with insulated electric conductor B, insulated electric conductor A.
The insulating tape width of above-mentioned connection insulated electric conductor A and insulated electric conductor B is not less than the radius sum of insulated electric conductor A and insulated electric conductor B;
The insulating tape width of the insulating tape width of above-mentioned insulated electric conductor A and insulated electric conductor C, insulated electric conductor B and insulated electric conductor D is: 2～8mm;
The thickness of above-mentioned each insulating tape is: 0.1～2mm;
Be provided with steel core among the above-mentioned insulated electric conductor A, steel core section is long-pending be not more than cross-sectional area of conductor long-pending 1/4.
The utility model compared with prior art owing to changed magnetic field and Electric Field Distribution on every side, reduces its reactance, and susceptance increases, and has obviously reduced the loss of line voltage distribution; Aspect technical measures, can effectively prevent the generation of stealing, electric leakage; There is steel core to increase the mechanical strength and the stretching resistance of lead among the conductor A; It is little also to have the line holding space simultaneously, and the stringing integrated cost is low, is not subject to the characteristics of external environment factor affecting.
