Galland developed the JG3612 section insulator at the request of Chinese railways. This insulator, designed for high speed, has a breaking strength of 9450 daN and a creepage distance of 1600 mm.
Advantage of the JG3612: its air isolation distance has been increased to 300 mm to optimize its insulation capacities and maintain its performance, even in severe environmental conditions. Compact, lightweight and easy to install, like all products resulting from Galland know-how.
This section insulator will be produced by our Chinese partner for the local market and at La Lande de Fronsac for all other markets. This technology transfer will notably make it possible to reduce costs, transport and limit the environmental impact of production. Currently in the approval phase, the JG3612 should enter service in late 2021-early 2022.
