Electric Powertek: Standard Type Disc Suspension Toughened Glass Insulator

Standard Type Disc Suspension Toughened Glass Insulator

Short Description:

Product Name: Glass Insulator

Type: Standard Type

Material: Toughened Glass

Insulators are a special type of insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for power poles, but gradually developed into high voltage power line connection towers with many disc-shaped insulators hanging on one end to increase the creepage distance, usually made of glass or ceramic. It’s called an insulator. Insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions, otherwise insulators will not play a significant role and will damage the service and operation life of the entire line.

The Advantages Of Glass Insulator

1 The raw materials used to manufacture glass insulators, in terms of their own composition, are more stable than those used to manufacture electric porcelain, creating good conditions for stabilizing the electrical and mechanical properties of glass.

2 Due to the transparency of glass, it is easy to detect small cracks and various internal defects and damages during appearance inspection.

3 The mechanical and electrical performance of tempered glass is much higher than that of porcelain, making insulators of the same type, and its size and weight are much smaller than porcelain insulators.

4 The mechanical strength of the surface layer of glass insulators is high, and the surface is not prone to cracks. The electrical strength of glass generally remains unchanged throughout the entire operation period, and its aging process is much slower than that of porcelain. Therefore, glass insulators are mainly scrapped due to self damage and occur within the first year of operation. However, defects in porcelain insulators only begin to be discovered after a few years of operation.

5 By using glass insulators, regular preventive tests on insulators during operation can be cancelled. This is because every type of damage to tempered glass can cause damage to the insulator, and operators can easily detect it during line inspections. When the insulator is damaged, the glass fragments near the steel cap and iron foot are stuck, and the mechanical strength of the remaining part of the insulator is sufficient to prevent the insulator string from breaking off.

Insulation Resistance Measurement Of Insulators

(1) The purpose of measurement is to check the insulation condition of insulators and discover defects such as insulation degradation and insulation breakdown.

(2) It is recommended to use a 5000V megohmmeter for measuring the insulation resistance of insulators on 35~220kV overhead transmission lines.
