220kV6 Electrical Composite Line Post Insulator

Most commonly used material for overhead line insulators is porcelain. But glass, steatite and some other special composite material may also be used sometimes.

The composite insulator can be customized according to requirements, offering advantages such as light weight, easy installation, pollution resistance, and easy maintenance. It is currently widely used in transmission systems around the world.

Composite line post insulators are available in various types, each designed for specific applications. Their structural height and creepage distance are tailored to meet diverse requirements. These insulators are predominantly utilized in substations and exhibit exceptional hydrophobic properties, aging resistance, leakage path tracking resistance, and electrical erosion resistance. They demonstrate high tensile and bending strength along with outstanding mechanical characteristics such as impact resistance, vibration resilience, and anti-brittleness. Furthermore, these insulators are lightweight and facilitate easy installation and maintenance. The installation dimensions at both ends match those of corresponding porcelain pillar insulators, enabling interchangeable use between the two types.

1. In high-voltage transmission lines: Composite post insulators can be installed on high-voltage transmission poles to support the conductors and prevent them from short-circuiting or causing sparks and fires due to contact with surrounding objects; they also improve the stability and reliability of the conductors and extend their service life.

2. In substation equipment: In some large power systems, such as power plants and substations, composite post insulators are also used in transformers and high and low-voltage distribution equipment to ensure safe and reliable operation and maintain the normal power supply of the power grid.
