Station post insulators high voltage is one property for insulator used for overhead lines. High voltage is one main technical data for customer’s inquiry.
Station post insulator high voltage level has
◆ 95kv, 110kv, 150kv, 200kv
◆ 250kv, 350kv, 550kv, 650kv, 750kv, 900kv
◆ 1050kv, 1300kv, 1470kv, 1550kv, 1800kv, 2050kv
Station post insulators are also called can and pin insulators, made from porcelain and polymer materials. The advantages of polymer post insulator
◆ High voltage insulator has lighter weight than porcelain or glass insulators
◆ Manufacturing process is easier than porcelain and glass insulators
◆ Easy to install and transport
◆ Most of high voltage insulators are made from silicone rubber materials and used worldwide
◆ Excellent hydrophobicity
Nowadays, more and more station post insulators made from polymer materials, but the South Africa used porcelain insulator because of high mechanical strength and less people understand the polymer Station post insulators high voltage.
