Environmentally-Friendly Gas-Insulated Metal-Enclosed Switchgear Air-12/T630-25 - China Suppliers and Factory

Overview

Introducing the Air-12 Environmentally-Friendly Gas-Insulated Metal-Enclosed Switchgear, a cutting-edge solution designed for modern power distribution needs. Utilizing a vacuum arc-extinguishing chamber and environmentally friendly gas as the primary insulating medium, this switchgear stands out for its innovative design that includes minimal solid insulating supports. The main circuit operates without encapsulation, maintaining a zero gauge pressure or slight positive pressure (gas pressure in the tank ≤ 0.02 MPa), ensuring exceptional insulation capabilities between phases and to ground in compliance with air insulation standards for distribution switchgear.

This eco-friendly gas-insulated metal-enclosed switchgear is one of the most sought-after three-phase AC intelligent solutions in the market, extensively used across diverse complete switchgear systems in China. As urban populations rise, the demand for reliable power solutions continues to increase, driving the need for environmentally friendly gas-insulated switchgear among suppliers and customers alike. The market potential for this innovative technology is vast and remains largely untapped.

Incorporating advanced features such as data collection and control, data processing and storage, and online monitoring capabilities, the Air-12 switchgear facilitates intelligent management of the distribution network. This ensures safe, reliable, high-quality, and efficient operation, enabling remote monitoring, control, and management of power systems. With its focus on grid optimization, electrical safety, energy management, and conservation, the system is ideal for various intelligent distribution applications, including transportation, manufacturing facilities, hospitals, schools, buildings, residential communities, and commercial office spaces. Trust in suppliers that offer this advanced technology from reputable factories to optimize your energy needs.

Frequently Asked Questions (FAQ)

What are the environmental temperature limits for normal equipment operation?

The equipment operates reliably within a maximum temperature of +40℃ and a minimum temperature of -25℃, with a 24-hour average temperature not exceeding 35℃.

Is this equipment suitable for installations at high altitudes?

Yes. The standard type is designed for altitudes up to 1500 meters under standard gas pressure. For installations exceeding 1500 meters, special instructions and consultation are required.

What is the protection rating (IP code) of the gas tank and shell?

The gas tank features an IP67 protection level, while the external shell is rated at IP3X, ensuring robust protection against ingress.

What is the gas leakage rate and arc extinguishing mechanism of this model?

The annual gas leakage rate is exceptionally low at ≤0.05%, and it utilizes the Vacuum Extinction method for highly efficient arc suppression.

What are the physical dimensions (width, height, depth) for different module configurations?

The height is 1336 mm and the depth is 850 mm (total 935 mm). The width (W) varies by configuration: 371 mm (1-way), 696 mm (2-way), 1021 mm (3-way), 1346 mm (4-way), and 1671 mm (5-way).
