Perforated Base Insulation Pins are professional equipment used in power systems, mainly composed of the following parts:

1. Needle body: This is the main part of an insulated needle, usually made of high-strength, high insulation materials such as ceramics or composite materials. The design of the needle body should not only ensure its insulation performance, but also have sufficient mechanical strength to withstand pressure and tension under various environmental and working conditions.

2. Metal terminals: Metal terminals are located at both ends of the needle body and are used to connect wires and other electrical equipment. These terminals are usually made of metal materials with good conductivity, such as copper or aluminum, and undergo tin plating or other surface treatment processes to prevent oxidation and corrosion, ensuring the reliability and stability of the connection.

3. Insulation sleeve: The insulation sleeve is wrapped around the outside of the needle body to further enhance its insulation performance and protective ability. Common insulating sleeve materials include silicone rubber, epoxy resin, etc., with good weather resistance and aging resistance.

4. Fixing device: In order to firmly install the insulation needle in the designated position, various fixing devices such as bolts, fixtures, etc. are usually equipped. These fixed devices not only need to have sufficient mechanical strength, but also need to have good corrosion resistance to adapt to various harsh environments.
