Carbon Slider
Carbon Sliders and collector shoe are to provide power to the locomotive through the third track. The core part of the collector shoe is a carbon slider, the quality of the slider affects the life of the shoes and the third track.
After years of unremitting efforts, our company has made significant achievements in the self-developed metal-impregnated collector shoes, from raw materials configuration, extrusion molding, baking to machining. In the railway industry, Kimwan is dedicated to provide customers with cost-effective, personalized products and solutions.
Pantograph is an electrical equipment for electric traction locomotive to obtain electric energy from contact network, which is installed on the roof of locomotive or moving car. The load current is introduced into the locomotive through the contact wires and the carbon slide plate of the pantograph. The degree of wear of the contact network as well as the Carbon Sliders are related to the quality of the Sliders, the bonding quality of the pantograph Sliders, the locomotive running speed, the locomotive power, the contact pressure between the pantograph Sliders and the contact wire, the transition resistance, and the contact area, and it depends on the interaction between the pantograph and the contact network.
collector shoe and Carbon Sliders Features
Suitable for electric locomotives as well as subway or light rail vehicles. Good bonding performance and low bonding resistance between Carbon Sliders and aluminum bracket.
– Good electrical conductivity, thermal conductivity and arc resistance.
– Long service life and durability
– Automatic bow lowering, high safety coefficient
– Can be customized and processed with various dimensions to match various types of pantographs.
