Gas Insulated Transmission Line (GIL): It is a high-voltage, high-current power transmission equipment that uses SF6 or mixed gas insulation and has a coaxial arrangement of enclosure and conductor. The conductor adopts aluminum alloy pipe material, and the enclosure adopts aluminum alloy shell enclosure. It is a high-tech product for transmitting large-capacity and low-loss electric energy, suitable for complex terrain, restricted installation conditions, high safety requirements, and public approachable occasions with dense population. The company has the supply capacity for GIL products with voltage levels of 500kV and below.
Product Features
- Extremely low dielectric loss. GIL conductor and enclosure have large cross-sections, low loss, so it can transmit extra-large capacity in ultra-high voltage transmission;
- High reliability and long service life. Good insulation performance, low dielectric loss, no aging problem, non-combustible, extremely high reliability. Average service life is more than 50 years;
- Strong transmission capacity. The transmission power of GIL can reach 4GW, with strong transmission capacity. It is beneficial to reduce the number of transmission circuits;
- Adopts compact closed structure, occupying less land than overhead lines. Flexible layout, can simplify system wiring and improve the power supply reliability of the entire system.
