Railway tunnel insulators

Railway tunnel insulators are insulators used for electric railway, small railway tunnel, railway traction lines, city subways, high speed railway and so on.

Railway tunnel insulator            Railway tunnel insulator

Railway tunnel insulators feature:
Can effectively prevent pollution flashover outage
Higher resistance to the power arc, higher ultra-violet (UV) radiation resistance
Good performance of hydrophobic, anti-fracture; superior electric property, strong; high electrical and mechanical strength
Suspension and span poles for high voltage and railway networks
Increase corrosion resistance, Increase its life span, Decrease single phase to the ground fault rate
Self-cleaning properties, Superior electrical strength, Suitability for polluted and salty atmospheres

Railway tunnel insulators have an effective use of a narrow corridor pressure transmission and applicable to rebuild of city net. Composite insulator can also reduce the tower height, saving manpower, material and financial resources. It has a superior performance than porcelain insulator.
