Pin Type Insulator BS 11kV 22kV 33kV Pin Type

Product Detail

BS 11kV 22kV 33kV Pin Type Standard: BS 137, IEC60383 Voltage:11-36kV Advantages of pin type insulators. High mechanical properties. Long-term service life. Good electrical performance. Good acid and corrosion resistance. Natural material, environmental friendly. Made by wet process porcelain or Dry process porcealin. As the name suggests, the pin insulator is secured to the cross-arm on the pole. There is a groove on the top of the insulator to hold the conductor. The conductor passes through groove and is bound by the same material as the conductor.
