Insulation bushings

The insulator sleeve is one of the main insulators located outside the devices themselves and the transformer box. These sleeves are used to remove the direct contact of different materials when attaching cables to metal poles. They serve to minimize electrolysis in this part. The main function is to provide Insulation bushings of conductive elements in or outside the wall through which they pass. Without an insulator, it is simply impossible to connect high voltage wires.

Insulator sleeves were previously made exclusively of porcelain. Today, their production has been modified. Insulator sleeves are resistant to abrasion and UV radiation. They can be cylindrical or cylindrical with ribs, through which a live wire passes. It withstands temperature differences very well, from an incredible -40F to + 266F.

Insulation bushings can be roughly divided into two types: those that are installed inside and those that are installed outside the device. Indoor sleeves are made of porcelain because it is necessary to withstand high vacuum and high voltage. They are located inside the metal bars and fixed with a metal flange and adhesive mass. Outside sleeves are usually built to have ribs spaced a short distance apart. They are insulators made of voltage parts.

In addition to these two types, there are other types of insulators, and which one to choose depends on the purpose and type of application. Whatever the case is, it is clear that it must be made of high-quality material that can withstand extreme mechanical and electrical strength. The most durable materials are porcelain, polymer, or tempered glass.
