12kV Vacuum Interrupter Nylon Embedded Pole
Composite Material Embedded Poles FOR Vacuum Circuit Breaker
Category: Embedded Pole
Tags: 12kV, Embedded Pole
Description
The Vacuum Interrupter Nylon Embedded Pole employs insulating material to securely combine a vacuum interrupter and the main loop conductive element, forming a single insulating support. This design offers several advantages, including simple assembly, stable weight, high reliability, and robust environmental pollution tolerance.
Advantages:
- High dielectric strength and mechanical strength.
- The housing of the embedded pole is made of fire-retardant nylon, enhancing its strength.
- Provides excellent protection for the vacuum interrupter against moisture, dust, and external damage.
- Suitable for various climatic conditions and site altitudes.
- Highly reliable with an extended service life.
- Easy assembly on circuit breakers.
- Maintains the highest quality standards.
- Maintenance-free.
- Efficiently enhances dielectric strength without using greenhouse gases.
