Catenary Ice Breaking / Traffic Device

Catenary Ice Breaking
Catenary Ice Breaking

The ice and snow weather has a great influence on the operation of the train. Catenary icing will damage the pantograph of the train, causing the train to lose its energy supply and fail to operate normally. The existing solution is to manually use traditional methods such as shovel, hammer, and pliers.The main core technology is to use the ultrasonic cavitation effect to destroy the ice structure and the adhesion of the ice, and to use the high temperature effect of the ultrasonic wave with a copper alloy brush to further remove the ice on the contact net. This design can greatly solve the impact of snowy weather on train operation.
