The transmission line connection point is a major weak point of inline operation. In the operation of often heat burned, thus causing power outages. 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.
Fiber optic cable construction is roughly divided into the following steps: preparation → routing project → fiber optic cable laying → fiber optic cable splicing → project acceptance.
The zinc oxide arrester 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.
The insulation material of wire and cable is an important structure to ensure the proper operation of the conductor. The operating life of the insulation material is an important indicator of the life of the cable. Адатта, what are the insulation materials we use for wire and cable?
High-voltage line arrester for 6 ~ 220kV AC transmission lines, is a new type of lightning arrester suspended and installed on the transmission tower.
In the case of high-voltage transmission line construction, many people working on projects often come across high-voltage power cable joints. Today, I would like to discuss the types of high voltage power cable joints and their applications with you. Алгачкы, let’s talk about what high voltage power cable joints are.
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.
At present, overhead cables are used to transport electricity over long distances. Conventional cables are mostly aluminum conductor steel reinforced (ACSR). Since the 1990s, carbon fiber composite cores (aluminum conductor composite core) have been used as the core bar of cables. ACCC has the following advantages over traditional conductors.
