126kV 145kV 252kV Busbar support porcelain insulator

Product Detail

Product Description

Busbar support porcelain insulators are essential components in electrical power systems, designed to provide both mechanical support and electrical insulation for busbars—conductive bars that distribute electricity within switchgear, substations, and industrial equipment. Crafted from high-quality porcelain, these insulators prevent current leakage between busbars and grounded structures, ensuring safe and efficient power distribution even in high-voltage environments.

Main Feature

Dual Functionality: Combines robust mechanical support to hold busbars securely in place with reliable electrical insulation, preventing short circuits and ensuring system safety.
High Insulation Strength: Made from dense porcelain material with excellent dielectric properties, capable of withstanding high voltage levels without breakdown.
Mechanical Durability: Resistant to mechanical stress, vibration, and thermal expansion, maintaining stability in demanding industrial and substation settings.
Weather and Corrosion Resistance: Unaffected by moisture, dust, and chemical exposure, making them suitable for both indoor and outdoor applications.
Compliance with Standards: Manufactured to meet industry specifications, ensuring compatibility with various busbar systems and power distribution setups.
