Pin type insulator is used above 132kv, but normally pin type insulator is used for high voltage lines up to 36kV. Sometimes line post insulators is called pin type insulator by some of electrical companies. Line post pin type insulator is used above 132kV.

The advantages of Pin type insulator is used above 132kv
◆ Exceeds ANSI and IEC electrical and mechanical requirements
◆ Resistant to impact damage, breakage, and vandalism
◆ 30 years of field experience
◆ Designed for use with all Tie and clamp Products
◆ Light weight for ease of handling

Pin type insulator is used above 132kv, the grade range of pin type insulator
◆ 10KV,11KV,12KV
◆ 22KV,24KV,25KV
◆ 33KV,35KV,36KV
◆ 66KV,69KV, 72.5kV, 110KV, 115kV, 132kV

Pin type insulator is used above 132kv with mechanical strength. Such as 11KV 2KN silicone rubber pin insulators are common insulator.
