The third-rail system of electrification is unrelated to the third rail used in dual-gauge railways.Third rail is a method of providing electric power to a railway train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are always supplied from direct current electricity
The Insulator and Protection cover system for Top-contact third-rail mainly consists of insulator or insulation support, protective cover and cover brackets. which ensures the safety power supply and normal operation of conductor rail, so as to prevent personnel of all kinds from injury. The system can meet DC750V or DC1500V, for which there are successful experiences in its design, manufacture and application.
