Pillar-Type Porcelain Insulator Composition

Pillar-type porcelain insulator is a columnar insulating device made of porcelain material, which usually consists of steel cap, porcelain parts and steel feet. Among them, the porcelain part is the key part to undertake the insulating function.

Pillar-Type Porcelain Insulator Characteristics

High insulating strength: the insulating strength of column type porcelain insulator is relatively high, which can play a good insulating role in high-voltage transmission lines.

High-temperature resistance: Because the porcelain material has good high-temperature resistance, the column-type porcelain insulator can work in high-temperature environments, such as in the mine underground.

Corrosion resistance: Pillar-type porcelain insulators have good corrosion resistance, can be used in harsh environments.

Structural stability: the structure of the column-type porcelain insulator is relatively stable, and can maintain its characteristics and performance in a long time of use.

Pillar-Type Porcelain Insulator Advantages

Excellent electrical performance: Pillar-type porcelain insulators have good electrical performance, which can effectively prevent current leakage and short-circuit accidents.

High mechanical strength: Porcelain material has high mechanical strength and can withstand large mechanical loads.

Good chemical stability: column-type porcelain insulators have good chemical stability, almost no aging deterioration.

Good thermal stability: porcelain material has good thermal stability, can maintain stable performance at high temperature.

Pillar-Type Porcelain Insulator Application

Pillar-type porcelain insulators are widely used in high-voltage overhead transmission and distribution lines for insulating and fixing conductors. They are also commonly used in outdoor power stations and lightning protection lines, etc. to ensure the safety and stability of power transmission.
