Factory directly 57-3 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...

Factory Promotional Dt 1/630 Transformer Bushing - 36kv 30NF250 High Voltage Transformer Porcelain Bushing – Johnson
Product Definition The transformer bushing is the main insulation device outside the transformer box. The lead wires of the transformer windings must pass through the insulating bushing to insulate between the lead wires and between the lead wires and the transformer shell, and at the same time play the role of fixing the lead wires. Due to the different voltage levels, insulating bushings include pure porcelain bushings, oil-filled bushings and capacitor bushings. Pure porcelain bushings are...
