BS1-JKLYJ parallel bundled wires

Parallel cluster overhead insulated cable (abbreviation: parallel cluster wire) is a product popularized and applied in the "Ten 5" scientific and technological planning of rural power grid construction of the State Power Corporation.

The reactance of the low-voltage power supply line is composed of impedance, capacitive reactance, and inductive reactance. The parallel bundled conductor adopts 3-phase 4-wire power supply, so that the unbalance of the 3-phase load of the distribution transformer is minimized, the neutral current is reduced, and the resistance loss is reduced. .Due to the tight symmetrical split structure, the inductance of the wire is reduced, the dielectric constant between the wires is increased, the capacitance is increased, the circuit reactance is greatly reduced, and the purpose of expanding capacity and reducing loss is finally achieved.

Due to the bundled combination of wires, the resistance to large breaking force is doubled compared with that of single wire, which reduces the single-phase wire breakage accident. When subjected to tension such as wind pressure and frost, the parallel insulation is not compressed, the operating safety factor is improved, and the lightning protection factor is improved. The effect of anti-strike, anti-stealing, and anti-leakage has been significantly improved. Due to its combination of splitability, it is easy to bridge the branches, and the variable capacitance combination is convenient. Lines, reduce towers, cross arms and porcelain parts, save a lot of metal. Due to insulation, the height of towers can be reduced, and it is not affected by complex environments such as trees and buildings. It can be laid along the wall to completely eliminate the need for poles, and the project cost is low. In addition Compared with single wire, the construction is simple, labor-saving and time-saving, and the construction cost is reduced. Compared with the conventional overhead bare wire mode, the parallel bundled wire has the advantages of low operating cost and obvious long-term benefits.
