Porcelain Insulator

Porcelain insulators are widely used in electrical power systems to provide reliable insulation and mechanical support for conductors and equipment. They are primarily employed in overhead transmission and distribution lines, where they prevent the flow of current to the ground and maintain the physical separation between energized parts. In substations and power plants, porcelain insulators are used to insulate busbars, switches, transformers, and other high-voltage components. Their strong dielectric properties, resistance to weathering, and mechanical durability make them suitable for use in harsh environments such as industrial areas and coastal regions. Additionally, they are used in railway electrification systems to insulate overhead lines, ensuring safe and efficient operation. Overall, porcelain insulators play a crucial role in maintaining the safety and reliability of electrical power infrastructure.
Our Porcelain insulators products are properly tested on different parameters before they are supplied in the channel. We offer them in the standard as well as customized specification according to the requirement of the valued customer. Porcelain insulators,are high on demand in among the Power Transmission and Distribution Suppliers

    

Porcelain Insulators

Features of Porcelain Insulators
Material : Made from a mixture of kaolin, feldspar, and quartz, fired at high temperatures.
Strength : Excellent mechanical strength and durability.
Electrical Resistance : High resistance to electric current, preventing leakage.
Weather Resistance : Withstands harsh environmental conditions like rain, pollution, and extreme temperatures.
Surface Glaze : Typically glazed to improve resistance to dirt and moisture.
Types :
Pin-Type Insulator: Mounted on a pin on the cross-arm of poles.
Suspension-Type Insulator: Hung from towers; used for high-voltage lines.
Strain Insulator: Designed to handle mechanical tension in lines.
Post Insulator: Used in substations and switchyards

Applications

• Overhead power lines
  Substations
  Electrical equipment like transformers and circuit breakers

Advantages

• Strong and durable, able to withstand heavy mechanical loads such as wind, ice, and tension from conductors.
  Offers high dielectric strength, preventing current leakage and electrical flashovers.
  Resistant to UV radiation, rain, snow, dust, and industrial pollution due to its glazed surface.
  Can withstand high temperatures without degrading, making it ideal for high-voltage applications.
  Durable material that offers decades of reliable performance with minimal maintenance.
  Unlike polymer insulators, porcelain does not catch fire or emit toxic gases under high temperatures.
