Description
Toughened insulator is a common electrical equipment, mainly used for insulation support and fixation in power transmission and distribution lines. The insulator body is the main component of a glass insulator, which is usually made of glass fiber reinforced plastic. This material has excellent insulating properties and mechanical strength. Able to withstand the voltage and mechanical loads found in high-voltage power lines.

Application
Glass insulators are used to fix wires to withstand the vertical load and horizontal tension of the wires and to insulate the wires from the earth. It is a special insulation control that can play an important role in overhead transmission lines. In the early years, glass insulators were mostly used on telephone poles, and gradually developed into high-voltage wiring towers with a large number of disc-shaped glass insulators hung on one end. It is to increase the creepage distance and is usually made of glass or ceramic and is called an insulator. Glass insulators should not fail due to various electromechanical stresses caused by changes in environmental and power load conditions, otherwise the glass insulators will not play an important role and will damage the service life and service life of the entire line.
We only accept bulk order instead of retail sales, greatly appreciated for your kindly understanding.
