Impressive technical specifications of the 40.5kV GIS<\/p><\/div>\n

Key Features:<\/strong><\/h2>\n
    \n
  • 40.5kV GIS <\/strong>is designed with SF6 <\/strong>gas insulation\u2014a type of gas with excellent dielectric and arc-extinguishing properties, commonly used in high-voltage switchgear. The fully enclosed gas chamber design prevents leakage, maintaining a leakage rate below 1\u2030 per year, ensuring stable operation for 20-30 years<\/strong> without the need for frequent maintenance. This is an ideal solution for electrical systems that require high safety and durability.<\/li>\n
  • 40.5kV GIS <\/strong>can withstand short-circuit currents up to 31.5kA for 4 seconds<\/strong>, ensuring the equipment continues to operate safely during system overload incidents. Additionally, the four-side internal arc resistance (AFLR) at 31.5kA for 1 second<\/strong> provides comprehensive protection for both the equipment and operators. These features make the GIS a reliable choice for switching stations with stringent safety requirements.<\/li>\n
  • The product meets heavy load systems thanks to its stable operation at a rated current of 2500A<\/strong>. With this load capacity, the 40.5kV GIS<\/strong> is suitable for main substations, large-scale industrial manufacturing plants, or data centers\u2014places where high stability is required and power interruptions are not permitted. This is a major advantage that helps optimize long-term operation without the need for early system expansion.<\/li>\n
  • Despite serving a 40.5kV power system, the 40.5kV GIS still possesses a compact design, significantly saving installation space compared to traditional switchgear. This is particularly important for projects with limited space such as indoor substations, RMU stations, or kiosk substations. Thanks to its modular structure, the cabinet also allows for flexible expansion when needed.<\/li>\n
  • The 40.5kV GIS complies with IEC 62271-100 and IEC 62271-200 technical standards, ensuring factors such as mechanical durability, switching performance, and electrical safety. These standards are mandatory conditions for application in large-scale power projects, key infrastructure, and modern industrial zones. This provides customers with peace of mind regarding the equipment’s quality and compatibility.<\/li>\n
  • With its enclosed structure, high-quality materials, and excellent corrosion resistance, the 40.5kV GIS has a long service life and requires almost no maintenance throughout its lifecycle. Minimizing maintenance activities not only saves costs but also reduces operational risks. This is a long-term investment solution that brings optimal economic efficiency to investors.<\/li>\n<\/ul>\n

    Practical Applications<\/strong><\/h2>\n
      \n
    • 35kV intermediate switching stations in factories or industrial zones<\/li>\n
    • Main switchgear systems in residential areas and commercial buildings<\/li>\n
    • Renewable energy projects such as solar power and wind power<\/li>\n
    • Substations in data centers and export processing zones<\/li>\n
    • Power grid systems requiring high operational stability and safety<\/li>\n
    • Space-constrained areas requiring high performance<\/li>\n<\/ul>\n
