Yuke EGG Repair Kit is professionally used for gas leakage, primarily targeting leaks in GIS/GIL, including insulator basins, bolt leaks, pinhole leaks, flange leaks, etc. The Yuke EGG Repair Series includes one set of EG10-TS, which is a three-component material. This material can strongly bond metals, epoxy resins, ceramics, and more. After curing, the surface is as hard as cast iron and has excellent flexibility, capable of withstanding thermal deformation differences between dual materials, long-term tolerance of 2MPa pressure, and offers excellent corrosion and pressure resistance against gases like SF6 sulfur hexafluoride.

The EGG Repair Kit can perform online repairs on leakage points without shutting down the system. For flanges, basins, etc., it can repair screws and joint surfaces as a unified whole without disassembling the screws, with repair effects lasting over 10 years. EGG Gas Leak Sealing Repair

Sulfur Hexafluoride Leak Repair, SF6 Leak Sealing, GIS/GIL Gas Leak Sealing

Insulator Disk Sulfur Hexafluoride Leakage, mainly manifested as gaps in the insulator disk leaking, bolts leaking SF6

Flange Sulfur Hexafluoride Leakage,

Ground Busbar SF6 Leakage, mainly manifested as insulation component leaks, including damage to ceramic and epoxy resin parts

Terminal Post Sulfur Hexafluoride Leakage, Gas Chamber Switch Sulfur Hexafluoride Leakage

Weld Seam Oil Leakage: Cracking or pinholes due to uneven welding stress, mainly occurring at heat sinks, reinforcing ribs, etc.

Flange Gasket Oil Leakage: Gasket aging, reduced elasticity, significant difference in thermal expansion coefficient between rubber and metal, causing leakage

Bolt Oil Leakage: Temperature difference changes, corrosion, etc., cause bolt loosening or rusting leading to oil leakage

Gas Oil Leakage: Mainly occurs at aging sealing surfaces, bellows, etc., often with entire areas covered in oil, making leak points difficult to locate

Valve Oil Leakage: Mainly occurs at the valve stem end cap, primarily due to wear, corrosion, and aging

Bushing Oil Leakage: Mainly occurs at the bottom of the bushing, at the junction of ceramic and metal, where inconsistent mechanical properties of different materials easily cause poor sealing

The key to transformer leak sealing lies in: 1. Whether the material can form an effective bond with the substrate in an environment with surface oil film

Yuke EGG Gas Repair Kit is specifically developed and produced for SF6 circuit breaker leaks. It can quickly repair sulfur hexafluoride gas leaks without shutdown or pressure relief. Combined with mature and targeted repair techniques, it ensures that even beginners can quickly become proficient and operate successfully.

Yuke Company not only provides repair materials but, more importantly, can develop corresponding process guidance based on your specific working conditions. For more complex situations, Yuke can dispatch professional technical personnel for on-site technical services.

,GIL insulation medium mostly uses SF6 gas, but SF6 gas has a strong greenhouse effect (global warming potential GWP is 23,800), which has a significant environmental impact and is internationally listed as a restricted greenhouse gas. In recent years, domestic and international focus has been on research into SF6 alternative gases, such as compressed air, SF6 mixed gases, and new environmentally friendly gases like C4F7N, c-C4F8, CF3I, and the development of environmentally friendly GIL[13-18] to improve the environmental benefits of equipment. In the early 20th century, Wuhan Nari Company in China conducted research on compressed air GIL technology but did not develop a product. Siemens and ABB developed SF6/N2 mixed gas GIL, which has been applied in engineering; State Grid Corporation of China developed an SF6/N2 mixed gas ultra-high voltage GIL prototype with a rated voltage of 1,100 kV. US GE Company used C4F7N/CO2 to form g3 gas, developed a 420 kV GIL, which was put into operation in the UK in 2017. It is evident that environmentally friendly GIL technology is still in its early stages. The development of high-voltage level equipment using SF6 mixed gases or completely SF6-free environmentally friendly gases, as well as the promotion and application of environmentally friendly gases in electrical equipment, require in-depth exploratory research.
