Products Introduction:

Parallel Volume Bundle Aerial Insulated Cable (Parallel Volume Bundle wire) is a product popularized and applied in the fifteenth scientific planning of the rural grid construction by the national electric power company. The scientific staff in our company borrowed the experience of applying the wiring harness from abroad, on the basis of which they successfully developed this product by improving and designing its technique and structure, filling the blankness of this product.

The reactance in low-voltage power-supplying circuit is composed of  impedance, capacitive reactance, and inductance. Parallel Volume Bundle  wire supplies power through three-phase and 4-wire, so as to minimize  the imbalance of three-phase load and to reduce the neutral wire  current, thereby reducing the resistance consumption. As a result of  using the compact symmetrical split structure, the wire inductance  lowers, and the dielectric constant between the lines is increased,  electricity capacity increases and the reactance is significantly  reduced so as to achieve the purpose of expanding the capacity and  reducing the  loss eventually.

    As the wires are bundled as a volume, the tensile strength has  been greatly increased than a single one, thus reducing the possibility  of single-phase getting broken. When suffering tensile force such as  wind pressure and frost, the insulation between parallels is not under  pressure, thus enhancing the operational safety factor and distinctly  improving the effects of preventing against thunder, electricity  stealing and leakage. The fissility of the volume makes it easy for the  interconnection between branches and convenient for transfiguration and  combination. Marked by the zero wire, it is clear to identify the  sequence of phase, thus mistakes can be prevented. The connection of the  parallel volume bundle wire uses fewer poles, horizontal bars and  porcelain materials, saving a lot of metals. As insulation can reduce  the height of the poles and can not be influenced by such complex  environments as trees and compounding, the wire can be laid along the  walls, thoroughly without poles, thus lowering the project cost. In  addition, compared with single wire, it makes the construction more  convenient and is more labor-saving and time-saving, thereby reducing  the construction expenses. Compared with the pattern of ordinary aerial  naked wire, the parallel volume bundle wire is advantageous in that its  operational cost is low and it has obvious long-term interests.
