Special Industry Application Scenarios

1.Electrified Railway and Rail Transit
● Scenario pain point: The contact network is subjected to long-term mechanical vibration and arc erosion, requiring a balance between insulation and mechanical durability.
● Glass insulator solution:
Adopting shockproof glass insulators (with elastic rubber structure), capable of withstanding vibration frequencies up to 50Hz;
Typical case: The contact network of the N700 series of Japanese Shinkansen vehicles has glass insulators with a lifespan of over 25 years and a failure rate of less than 0.1 times per thousand kilometers.

2.New energy generation grid connection
● Scenario requirements: Wind and photovoltaic power plants have large output fluctuations, and insulators need to withstand high-frequency harmonics and overvoltage.
● Advantages of glass insulators:
High dielectric constant (ε=7-8) suppresses partial discharge caused by high-frequency harmonics;
Typical case: Jiuquan Wind Power Base in Gansu, China, uses glass insulators to collect lines, reducing harmonic losses by 15%.

3.Mining and Heavy Industry Zone
● Pain points in the scene: serious pollution from dust, acid mist, and heavy metals, and traditional insulators are prone to fouling and flashover.
● Glass insulator solution:
Surface coated with TiO ₂ photocatalytic coating to decompose organic pollutants;
Typical case: The 66kV power supply line of Escondida copper mine in Chile has reduced the annual pollution flashover frequency of glass insulators from 7 to 0.
