Environmentally-Friendly Gas-Insulated Metal-Enclosed Switchgear - China Suppliers & Factory Solutions

,

Overview

,

The Air-12 Environmentally-Friendly Gas-Insulated Metal-Enclosed Switchgear is a cutting-edge solution designed with a vacuum arc-extinguishing chamber. This innovative switchgear uses eco-friendly gas as the primary insulating medium, along with minimal solid insulating supports. Its main circuit maintains either a zero gauge pressure or slight positive pressure during normal operation (gas pressure in the tank ≤ 0.02 MPa). The insulation capabilities between phases and with respect to ground are compliant with air insulation standards for distribution switchgear operating under zero gauge pressure.
As one of the most prevalent three-phase AC intelligent eco-friendly gas-insulated cabinets, this switchgear is extensively utilized across various complete switchgear systems in China. With the increasing concentration of the population and the corresponding demand for energy, the need for environmentally friendly gas-insulated switchgear is set to rise, presenting significant market potential for suppliers and factories alike.
Moreover, the Air-12 switchgear is equipped with advanced functionalities such as data collection and control, data processing and storage, online monitoring, and sophisticated analytical capabilities. This facilitates intelligent online monitoring and management of the distribution network, ensuring that it operates safely, reliably, and efficiently. It also enables remote monitoring, control, and management of the electrical distribution network, meeting the growing demands for grid optimization, electrical safety, energy management, and conservation. The system finds extensive applications in diverse intelligent distribution fields, including transportation, manufacturing, healthcare, educational institutions, commercial buildings, and residential communities.

    Frequently Asked Questions

    Q1: What are the normal operating temperature limits for this equipment?
    The equipment is designed to operate in environmental temperatures ranging from a minimum of -25℃ to a maximum of +40℃, with a 24-hour average temperature not exceeding 35℃.
    Q2: Can the system be used at altitudes higher than 1500 meters?
    The standard type is rated for altitudes up to 1500 meters under standard gas pressure. For installations exceeding 1500 meters, special instructions and custom consultations are required.
    Q3: What is the protection level and annual gas leakage rate?
    The gas tank features an IP67 protection rating, while the shell holds an IP3X rating. The annual gas leakage rate is exceptionally low at ≤0.05%.
    Q4: How does the mechanical service life differ between modules?
    The mechanical service life varies by module: the V Module (Vacuum Breaker) has a life of 10,000 operations, the C Module (Load Switch) and F Module (Composite Apparatus) support 5,000 operations, and the Isolation/Earthing Switch supports 3,000 operations.
    Q5: What are the dimensions for different loop configurations?
    While the height is 1336 mm and depth is 850 mm (935 mm total) across all configurations, the width (W) scales as follows: 1-way: 371mm, 2-way: 696mm, 3-way: 1021mm, 4-way: 1346mm, and 5-way: 1671mm.
    Q6: What arc extinguishing technology is used in the switchgear?
    This switchgear utilizes the reliable Vacuum Extinction method for high-efficiency and safe arc extinguishing during operations.
