Product Details
The gas insulated switchgear terminal (GIDU), also known as the GIRU cable terminal, is a critical element for connecting high voltage cables to GIRU equipment. Sulfur hexafluoride (SF6) is used as external insulation and the device is enclosed in a metal housing. Key Features:
• Compact design, space saving:is not affected by the external environment, and the size of the outer epoxy resin insulating shell is much smaller than that of external terminals, making the design very compact.
• Completely closed and insulated design, highly adaptable to the environment:operation in a completely enclosed environment, unaffected by atmospheric conditions, pollution, altitude, etc. Combined with the excellent insulating properties of SF6, it demonstrates extremely high reliability.
• Oil-free "dry type" design, safe and environmentally friendly:The main structure is a completely dry structure without insulating fillers inside, which completely eliminates the risk of oil leakage.
• Connection via plug insert, convenient for installation and maintenance:The epoxy sleeve can be pre-installed on the equipment, eliminating the need to open the gas chamber of the switchgear on site, making installation simple and quick. It also has the advantages of being reusable and interchangeable.
• Excellent electrical and mechanical properties:The stress cones of the insulating core components are primarily made of ethylene propylene diene monomer (EPDM), which are compressed by spring devices to maintain a stable pressure at the interface over a long period of time. The voltage range is from 10 kV to 750 kV, providing a wide range of applications.
Overall, due to the above-mentioned significant advantages, GIS cable terminations have become the preferred solution for connecting cables to GIS equipment in high-voltage and ultra-high-voltage power systems.
