In the wiring of weak current projects, we usually bury the wire tube in the wall first. Such a hidden design will not affect the beautiful effect of decoration. However, after the AAAC Cables tube is buried, threading from the inside is a troublesome thing. Sometimes we can’t wear a wire after tossing for a … Read more
The transmission capacity of superconducting AAC Cable is much larger than that of conventional cable. The power transmission capacity of a 10KV three-phase coaxial high temperature AC superconducting cable is greater than that of a conventional 110kV cable, but the transmission loss is only one fourth to one fifth of that of a conventional cable, … Read more
1. Market demand China’s power grid construction investment will continue to grow steadily, including smart grid construction, new energy construction and distribution network transformation, which will bring a new round of development opportunities for the cable accessories industry. The “long-distance, large-scale, high-capacity and high-voltage” pattern of power grid construction will further stimulate the demand for … Read more
In order to improve the flexibility and integrity of wires and cables, two or more single wires are intertwined in the specified direction. This process is called stranding. The whole stranding process is divided into conductor stranding, cable forming, braiding, steel wire armor and winding. Any problem in any process will directly affect the cable … Read more
The service life of control cable is determined by the air oxidation induction period of sheath raw materials. Generally, the design scheme of control cable is applied for 20 years, which is the most applied life of control cable. Although the specific daily life is likely to be longer, from the perspective of safety, the … Read more
A quality inspection organization has conducted a sampling survey on domestic wires and cables. The results show that the qualified rate of wires and cables in production enterprises that have passed ISO 9000 certification is less than 90%, while the qualified rate of products in small-scale wire and cable production enterprises that have not passed … Read more
(1) Being struck by lightning. Most of the high and low voltage lines of power transformers are introduced by overhead cables. Because they are located in mountainous forests, the probability of lightning strikes is high. Therefore, during the thunderstorm season each year, the proportion of distribution transformers damaged by lightning strikes accounts for more than … Read more
1、 What is cable formation Definition of cable forming: the process of twisting multiple insulated cores into AAC Cables according to certain rules. 2、 The role of cable forming in cable production Cable forming is one of the important processes in the production of multi-core cables. The three core, four core (one core is the … Read more
The cross-linked polyethylene cable material (XLPE) can make the aggregate structure of the insulating material in a reasonable state through the cross-linking process, and can increase the long-term working temperature of the power cable to 90 ℃, and the instantaneous short-circuit temperature is 170 ℃ ~ 250 ℃. The performance remains unchanged while other performances … Read more
The insulation resistance of directly buried power cables is reduced and the phenomenon of cable line failures often occurs, especially when the cable insulation is damp, it is easy to cause the insulation resistance of directly buried power cables to decrease and substandard 1. The cable raw materials are damp The raw materials used for … Read more
