Wholesale Discount 57-1 Post Insulator - P-70 Porcelain Post Insulator – Johnson
Product Definition Post insulator is a special insulation control which can play an important role in overhead transmission line. In the early years, pillar insulators were mostly used for telephone poles, which were gradually developed to hang a lot of suspension-like insulators at the end of the high-voltage wire connection tower to increase the creepage distance. They are usually made of silica gel or ceramic, and are called insulators. Insulator in overhead transmission lines with two b...
