During the operation of wires and AAC Cables, they will heat due to the existence of resistance. The resistance of the conductor is generally very small, and its heating power can be expressed by the formula q = I ^ 2R. Q = I ^ 2R shows that for a section of conductor in actual … Read more
In low-voltage distribution system, the current of zero line is smaller than that of live line. This is because when the three-phase load is balanced, the three-phase current is completely offset, and the zero line current is zero; However, when the AAC Cables consumption of three-phase load is unbalanced, the three-phase current cannot be completely … Read more
In the field of wire drawing, the sliding water tank wire drawing machine is widely used, that is, there is a gap between the speed of the drum and the AAAC Cables, so that the wire can slip on the contact surface with the drum, resulting in sliding friction, which drives the wire to realize … Read more
Discussion on the cable production process: conductor twisting and twisting : the process of twisting many small diameter monofilaments into a large cross-section conductive core according to certain rules. 1. There are two types of twisted wires: normal twisted wires and irregular twisted AAC Cables. Ordinary strands can be divided into ordinary concentric single stranded … Read more
The National Bureau of statistics released the output and growth rate of China’s major industrial products from January to March. Among the 100 major industrial products listed, except for fax machines, only 4 products showed a year-on-year decrease in output from January to March 2020. Among them, the cumulative output of abc cables was 63.996 … Read more
The advent of power cables has greatly improved the safety of power generation, transmission, transformation, supply, distribution, and use of electricity. Single-core power cables appeared first. As there are more and more occasions for three-phase four-wire power supply, three-phase five-wire power supply and multi-loop power supply in actual use, the requirements for occupied space and … Read more
