Power Fittings Manufacturers Share Knowledge You Must Know About Power Fittings

Power fittings are metal accessories that connect and combine various devices in the power system and play a role in transmitting mechanical loads, electrical loads and certain protective functions. With the development of China's economic level, the speed and level of my country's power development have reached a fairly high level. The application of electricity has spread to almost every corner of my country, and the demand for power fittings has also reached an unprecedented level.

Cable lugs can be divided into different types according to different classification standards. Most fittings need to withstand large tensile forces during operation, and some must also ensure good electrical contact at the same time. It is related to the safety of wires or towers. Even if one is damaged, it may cause line failure. Therefore, the quality, correct use and installation of fittings have a certain impact on the safe power transmission of the line. Therefore, we must have a certain understanding of fittings when using them. Let's take outdoor high-voltage disconnectors as an example to understand the knowledge about its application.

Scope of application:

GW4 series outdoor disconnectors are suitable for installation on outdoor high-voltage distribution equipment lines for the purpose of opening and closing the lines when there is voltage and no load.

Environmental conditions for use:

1. Altitude not exceeding 1000m;

2. Ambient medium temperature not higher than +40℃ and not lower than -30℃ Note: When the altitude and ambient medium temperature cannot meet the above conditions, this type of isolating switch can be used according to the requirements of GB311-64*** standard.

Isolating switches are not suitable for:

1. Places with conductive or chemically active gases and steam;

2. Places with large amounts of dust;

3. Places with fire and explosion hazards;

4. Places with severe vibration or impact (such as next to electric picks, excavators, etc.).
