Buses are increasingly replacing wire and cable in indoor low-voltage transmission trunking projects. Has been promoted in foreign developed countries and China's Hong Kong and Macao. In Guangzhou, Guangdong, China, more than 90 per cent of the trunking to the floors of buildings of more than 12 floors use bus ducts; bus ducts should be used from 630KVA transformers to distribution cabinets.

Bus ducts are also popular in large and medium-sized cities for public building projects, hotels and office buildings. Bus ducts are the best choice for indoor power transmission trunking with rated voltage below 1000 volts. When installing it, it is important to pay attention to the correct placement according to its corresponding phase sequence, number, direction, and installation signs, and then match it to the bus duct or other devices next to it before installing it correctly. So what do I need to pay attention to during the installation of bus ducts?

Horizontal installation of bus ducts should be noted. When connecting the bus duct, first check whether the whole bus duct is intact. After confirmation, make the connection. When piercing, sewage and other debris cannot enter the bus. Also, be careful that the bus duct connection point is not in the through-wall portion. To understand the horizontal installation, pay attention to the horizontal fixing of the platen when installed on the support bracket. When installing, some length should be reserved as needed. When the busbar passes through the expansion joints or settlement joints of the building, its settlement node needs to be set. Also pay attention to the distance between the bus duct and the neighbouring bus duct when installed horizontally.

Vertical installation of busbar notes:First of all, pay attention to the distance between the busbar and the ground as high as possible, the distance between the floors should not be less than 60cm. don't make holes in the place where there is a floor. Of course, when making holes, pay attention not to have sewage and debris. When the length of bus ducts laid in a straight line exceeds a certain distance, pay attention to set its expansion joints.
