Explanation

Electrified Railway Composite insulator is a new insulator, it is good to antifouling properties of composite insulators, shock, impact resistance, anti-brittle performance characteristics, widely used in electric railway, the railway tunnel electrification systems. Is porcelain, glass insulators irreplaceable product.
This product is suitable for complex operating conditions electrified railway tunnels, can effectively prevent the pollution flashover, reducing cleaning maintenance workload, it is at work not only by the tension (long rod insulators PQE₁~ PQE₄), sometimes by song force (line oars insulator PQX₁ ~ PQX₅), due to their small size, when the tunnel clear space is small, especially in heavy polluted areas are porcelain, glass and other insulators can not be replaced products.
