Standard glass insulator U160BS

U160BS is a standard disc-shaped suspension tempered glass insulator designed specifically for high-voltage and higher voltage AC/DC transmission lines, playing a critical role in insulation and suspension of conductors in power systems. Its core advantages are reflected in mechanical performance, electrical performance, thermal stability, and maintenance convenience.

Design advantages

Zero value self explosion characteristic

Tempered glass insulators will automatically rupture when their insulation performance drops to a critical value, but the residual section still maintains tensile strength and electrical performance, avoiding line breakage accidents.

After self explosion, the residual hammer of the iron cap is hung on the line for easy positioning and replacement by operation and maintenance personnel, reducing maintenance costs.

Transparency and ease of inspection

The glass material is transparent and can detect small cracks and internal defects through visual inspection, without the need for disassembly or special equipment, improving inspection efficiency.

Lightweight and high strength

Compared to porcelain insulators, U160BS has a weight reduction of about 30%, a smaller volume, and is easier to transport and install. At the same time, its mechanical strength has been increased by 1-2 times.

3、 Application scenarios

Voltage level: Suitable for 110kV to 500kV AC and DC transmission lines.

Environmental adaptability:

High altitude areas: The electrical strength is adjusted as the air density decreases, and the performance is confirmed to be stable.

Polluted areas: Pollution resistant designs (such as U160BLP/155) can be selected, with a 20% -30% increase in creepage distance compared to ordinary designs.

Extreme climate zone: The temperature resistance and arc resistance characteristics meet the needs of high temperature, lightning strikes, ice damage, etc.

Economy and stability

Low lifecycle cost: The zero value self explosion characteristic reduces the frequency of preventive testing and cleaning, and maintenance costs are reduced by about 40% compared to ceramic insulators.

Long operating life: Tempered glass has uniform internal stress distribution, better aging performance than ceramic insulators, and good long-term stability.
