What is the lighting bus groove

The lighting bus-bar groove is a kind of enclosed metal device composed of copper and aluminum bus-bar, which is used to distribute high power to each component of the decentralized system. In the indoor low-voltage power transmission trunk line engineering projects have increasingly replaced the wire and cable. As a new type of distribution conductor, the plug-in bus-bar groove comes into being. Compared with the traditional cable, it can fully display its superiority when the current is high, the contact resistance and temperature rise at the junction of the two ends of the bus-bar slot and the junction of the branch-bar port are greatly reduced, and the high quality insulating material is used in the bus-bar slot, so the safety and reliability of the bus-bar slot are improved, and the whole system is more perfect. Classified by purpose, the bus bar groove is generally composed of the bus bar groove at the beginning end, the straight bus bar groove (with and without sockets) , the l-type vertical (horizontal) curved bus bar, the z-type vertical (horizontal) offset bus bar, the t-type vertical (horizontal) three-way bus bar, the x-type vertical (horizontal) four-way bus bar, the variable volume bus bar groove, the expansion bus bar groove, the terminal head, the terminal junction box, the socket box, the relevant accessories of the bus bar groove and the fastening device, etc. .
