这 transmission line connection point is a major weak point of inline operation. 在运行中经常受热烧毁, 从而导致停电. The analysis of the wire connection point heating problem, and timely adoption of appropriate preventive measures, will effectively avoid the wire connection point overheating. This causes the wire connection point to burn off the accident. Analyze the causes of wire connection point heating, and understand the theoretical basis for the temperature rise of high-voltage lines. At the same time, mastering the prevention and solution measures to deal with the connection point heating problem, to ensure the safe and reliable operation of the line has practical significance.

安装氧化锌避雷器的正确步骤是什么?
这 氧化锌避雷器 uses zinc oxide resistance as the main component, which greatly improves the voltammetric characteristics of the arrester and increases the through-current capability. When the arrester is in normal operation, the voltage flow through the arrester current is only microampere. When the overvoltage is received, the excellent non-linear characteristics of the arrester play a good role.
A lightning arrester is mainly used to protect electrical equipment from lightning intrusion overvoltage and operating overvoltage on its power equipment insulation damage.
高压电力电缆接头的类型
在高压输电线路建设的情况下, 许多从事项目的人经常会遇到高压电力电缆接头. 今天, I would like to discuss the types of high voltage power cable joints and their applications with you. 第一的, let’s talk about what high voltage power cable joints 是.
阻燃热缩管简介
The main role of heat shrink tubing in a circuit is to protect important devices and circuits from damage and impact. Although it does not have any particular impact on the operation of the circuit, it is often the key point that determines the success or failure of the entire design. With the rapid development of the electronics industry, flame-retardant heat shrink tubing is also inseparable from the electronics industry, more and more electronic products need to use flame retardant heat shrink tubing for protection. The flame retardant processing of the heat shrink tube, when attacked by external fire sources, can effectively block, delay or stop the transmission of flame, to achieve the effect of flame retardant.
电线电缆导体预热时需要注意什么?
Wire and cable are used to transmit electrical (磁的) 活力. 线材产品的信息与电磁能量转换的实现. 广义上讲, wire and cable are also referred to as cable, and narrowly speaking, cable refers to insulated cable. It can be defined as a collection of the following parts: one or more insulated wire cores, and they may have their cladding, total protective layer, and outer sheath, the cable can also have additional conductors without insulation.
电线杆上的白色陶瓷——电绝缘体
The main role of electrical insulators is to provide mechanical fixation and electrical insulation for electrical equipment and conductors in power transmission and supply lines. Insulators are currently available in three main materials, namely ceramic, tempered glass, and organic composite materials. Insulators have played an important role in the development of the electric power industry.
