Since the atmospheric pressure is low in a high-altitude environment, discharge is very easy to occur, and the arc is thick. After the AC crosses zero, the circuit is very prone to discharge, and the arc is easy to re-ignite and is difficult to extinguish. Therefore, the insulation of power transmission and transformation equipment operating at high altitude and low pressure should be strengthened. Its influence must be fully considered when calculating insulation coordination, and the pollution lightning voltage should be appropriately increased. Generally, when the altitude is above 3000 m, the pollution voltage value should be considered to be increased by about 25% accordingly. ...

Cold-shrinkable cable terminals are made of elastomer materials (commonly used silicone rubber and ethylene-propylene rubber) that are injection vulcanized in the factory. They are then enlarged and lined with plastic spiral supports to form various cable accessories. During on-site installation, these pre-expansion pieces are placed on the treated cable ends or joints, and the internally supported plastic spiral strips (supports) are pulled out and pressed against the cable insulation to form a cable accessory. Because it relies on elastic retraction at room temperature, rather than heating and shrinking with fire like heat-shrinkable cable accessories, it is commonly known as cold-shrinkable cable accessories. ...

Power cable accessories are products that connect cables to power transmission and distribution lines and related power distribution devices. They generally refer to the intermediate connections and terminal connections of various cables in cable lines. Together with the cables, they form a power transmission network. ...

A low voltage busbar insulator is a component that is used to insulate and support busbars, which are metal bars used to distribute low voltage electrical power. The insulator is designed to prevent e ...

In order to meet the needs of use in special occasions and harsh conditions, halogen-free heat shrinkable sleeves have good mechanical and insulating effects, as well as resistance to aging, corrosion, good strength, a service life of more than 20 years, easy to use, and very good resistance combustion performance. Although halogen-containing heat shrinkable sleeves also have good flame retardant properties, when a fire occurs, such halogen-containing flame retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas, causing secondary hazards. ...

Heat shrinkable tubes are not an important component in circuit design, but they play a role in protecting circuits and important components in circuits. However, only by selecting the heat shrink tube according to the appropriate size can the circuit be protected to the greatest extent. ...

Although heat shrinkable tubes are not directly involved in the composition of electronic circuits, they play a role in protecting important components and circuits. But in fact, the role of heat shrinkable tubes goes far beyond simply protecting circuits. In addition, heat shrinkable tubes also play a very important role in other fields. This article will introduce you to some other uses of heat shrink tubing besides protecting circuits. ...

According to the analysis of the pollution flashover mechanism of insulators, it is shown that pollution flashover is mainly caused by factors such as the accumulation of contamination on the surface of the insulator, moisture of the contamination material, and external applied voltage. From this, it can be concluded that direct cleaning, increasing the specific creepage distance, spraying antifouling materials and other prevention measures are pollution measures. ...

In the power transformation and distribution device, the current sent from the power supply will first be concentrated on the busbar, and then the current will be distributed from the busbar to various lines for users to use. Since the busbar is a conductor that collects and distributes current, it plays an important role in power transformation and distribution devices. The busbar is also called the busbar. It is divided into three types according to material properties: copper, aluminum, and steel. However, considering the conductivity, resource reserves, price, etc., it is more reasonable to use aluminum as the busbar material. Steel is mostly used for grounding and zero busbars. ...
