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.
Characteristics of the products:
Relatively low circuit loss, with 5% - 10% loss.
Making constructions convenient, time-saving and labor-saving and fixing expenses lower.
