Product Description

SRM Series inflatable switchgear GI5(Gas Insulated Switchgear)

Product Description

Product Overview:
The SRM series gas-insulated SF6 metal-enclosed fully insulated ring main unit has successfully passed the type test conducted by the National Supervision and Inspection Center for Low and High Voltage Electrical Appliances. This product is widely used in 10kV and 24kV distribution systems and is an ideal choice for power transmission and distribution systems in urban and rural areas.

Product Features:

    1.    Modular Design:
The SRM switchgear is designed in a modular unit structure, offering flexibility for different applications. It is available in two types: fixed units and expandable units, providing versatility to meet the needs of compact power distribution systems.
    2.    Completely Sealed System:
This switchgear is a fully sealed system where all live components and switches are enclosed within a stainless-steel shell. This sealed design ensures that the entire unit is unaffected by external environmental conditions, guaranteeing safe and reliable operation with no maintenance required.
    3.    Flexible Configuration:
By selecting the expandable busbar, any combination of units can be achieved, allowing for full modularization. This design ensures that the switchgear can be tailored to specific needs, providing maximum flexibility for power distribution networks.
    4.    Smart Automation Solutions:
The SRM series can be equipped with intelligent automation solutions, minimizing on-site installation and commissioning work. This greatly reduces operational complexity and helps to streamline the installation process.

Applications:
The SRM series switchgear is widely used in urban and rural distribution networks, industrial and mining enterprises, and power distribution systems in residential areas. It is ideal for applications where a compact, fully insulated, and maintenance-free switchgear solution is required.

Advantages:

    •    Environmental Resistance: The sealed stainless-steel enclosure ensures that the switchgear operates reliably in harsh environmental conditions without being affected by dust, moisture, or pollution.
    •    Compact Design: The modular design allows for compact installation, saving space while providing high operational efficiency.
    •    Maintenance-Free: Thanks to the fully sealed design and the use of SF6 gas insulation, the switchgear requires no regular maintenance, reducing operational costs and downtime.

Technical Specifications:

    •    Voltage Ratings: 10kV, 24kV
    •    Standards Compliance: The SRM series complies with national and international standards for switchgear, ensuring high performance, safety, and reliability.

Precautions:

    1.    Installation: Ensure that the switchgear is installed by qualified personnel following the manufacturer's guidelines to guarantee safety and optimal performance.
    2.    Environmental Considerations: Although the unit is designed for harsh environments, ensure that it is placed in a location that meets the operational conditions specified by the manufacturer.
    3.    Operation and Safety: Follow all safety protocols during operation, especially when working with high-voltage systems, to prevent accidents.

The SRM series gas-insulated switchgear is a highly reliable, compact, and flexible solution for modern power distribution systems, offering advanced technology and robust performance for both urban and rural environments.
