Strain type insulator is one of electrical insulator, sometimes it can call suspension insulator and stay insulator used on electrical power lines.

If strain type insulator is one of suspension insulator, can be divided into
◆ Suspension type insulator
◆ Tension insulator

If strain type insulator is one of stay insulator, can be divided into
◆ Porcelain stay insulator
◆ Silicone guy strain insulator

Strain type insulator can be used on
◆ Transmission and distribution lines
◆ Pole lines
◆ Electrical equipment

According to insulator materials, Strain type insulator can be divided into
◆ Porcelain Strain type insulator
◆ Polymer Strain type insulator

Strain type insulator includes electrical and mechanical properties, such as power frequency voltage, puncture withstand voltage and impulse withstand voltage.
