Product Introduction

Product Features

  1. Excellent Performance and High Reliability

The circuit breaker offers a mechanical lifespan of up to 20,000 operations and a grounding making capacity of 5 times. The partial discharge of the complete cabinet is ≤10pC, meeting long-term operation requirements. The dry air used has high stability and is non-toxic, making it suitable for various ambient temperatures. The gas tank adopts laser welding technology with an annual gas leakage rate of ≤0.01%. It is filled with dry air at a slight positive pressure of 0.02MPa, ensuring operator safety. The switch uses a composite insulation structure, significantly improving the insulation strength and durability of the circuit breaker.

  1. Green and Environmentally Friendly, Energy Efficient

Dry air is used as the insulating gas, which is environmentally friendly with a GWP <1.
The pole adopts an integrally formed insulating cylinder structure, ensuring process stability and high production efficiency. With a fully insulated and fully enclosed design, the product requires no maintenance throughout its entire lifecycle. The gas does not need to be recycled, reducing maintenance costs.

  1. Compact Structure and Comprehensive Solutions

The cabinet width can be reduced to 375 mm, making it compact and saving floor space.
The switch supports upper and lower isolation configurations and can be flexibly combined and connected in cabinets as needed, meeting the requirements of various application scenarios.
