Electrical bushing insulator

Electrical Bushing insulator is normally used by transformer manufacturers as a means of electrical / mechanical connection from the outside of the tank (cables or overhead lines) to the inside of the tank (transformer windings). Electrical bushing insulator can be used in various other applications - for example ‘through-wall’ bushings.

There are typically three types of major insulating material used in electrical bushing insulator manufacture.

Electrical bushing insulator is made from porcelain:
Porcelain insulation is a proven technology providing a low cost, long life and maintenance-free solution. It is able to withstand all environmental conditions. Porcelain insulators are normally supplied with brown glaze but grey glaze can be provided if required.

Electrical bushing insulator is made from resin:
Resin insulation is typically used in bushings rated at 12kV and below. It can provide advantages in certain applications. Resin provides some manufacturing advantages over porcelain in that complete hollow bushing insulator can be produced faster and are able to meet more demanding dimensional tolerances.

Electrical bushing insulator is made from composite:
Composite insulation is useful in applications of high vibration and possible urban vandalism due to its natural flexibility and ability to withstand impacts.

We mainly produced porcelain electrical bushing insulator and composite bushing insulator, if you want to need these two type bushing insulators, please contact Orient Power.
