Track Lead Junction Box is an adequate apparatus which is manufactured by JMV, basically a device used for power tracks (track circuit works on the power source that is connected at one end further attached with relay the other end) thus the power invites the fault occurrence in the track due to over-flow of current. To encounter such risks from track the TLJB should be equipped along with the same. The device upholds many decisive elements that together forms an outstanding track lead junction box. It has dual connection with four terminals that have great strength to work efficiently. The device is made up of FRP material which is environmental friendly thus prevent the system from the various influences such as dirt, rain water, humidity and explosion due to some other disturbances. It shall be located to the distance at every 350m to grant proper safety. We offer two types of TLJB as per the concern, the first one is with the sliding lock and another one with the nut or bolt jointing.
