2021 Good Quality 10nf3150 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...

2021 Latest Design Low Voltage Porcelain Insulator - BS 1618 Shackle Electrical Porcelain Insulators for Low Voltage – Johnson
Product Information Low voltage line insulators are used for insulation and fixing of power line conductors with power frequency AC or DC voltage below 1KV. There are mainly needle type, screw type, spool type, tension and tram line insulator, etc. Butterfly and spool insulators can also be used for insulation and fixation of conductors on low-voltage line terminals, tension and corner rods. Tension insulator is used for insulation and connection of pole stay wire or tension conductor. In the...

Reasonable price for 160kn Fog Type Glass Insulator – High Voltage 160kn Disc Suspension Toughened Glass Insulator U160B – Johnson
Product Definition Glass insulators an insulator made of tempered glass. Its surface is in the state of compression prestress, such as crack and electrical breakdown, glass insulator will break into small pieces, commonly known as “self-explosion”. This feature eliminates the need for “zero value” detection of glass insulators during operation. The glass insulator is the crystallization of the combination of glass and insulator. Because of the characteristics of glass ...
