We all know that the main thing of the bus machine is the bus, but most people don't pay much attention to the installation of the bus. In fact, the installation of the bus is not that difficult.   What is a bus first? How many kinds of busbars are divided into? The following bus machine manufacturer will give you the answer.   There are two main types of bus bars. One is hard bus bars, which are also called bus bars, and the other is soft bus bars, which include combined soft bus bars.   According to the material, the bus bar can be divided into three types: aluminum bus bar, copper bus bar and steel bus bar; according to the shape, it can be divided into four types: belt, groove, tube and combined soft bus.   According to the busbar installation method, there are 1, 2, 3, and 4 strip busbars per phase, and there are 2, 3, 10, 14, 18, and 36 combined flexible busbars. 1. Closed and plug-in busbar installation. The closed and plug-in busway is a relatively advanced power supply line. It is used as a feeder and distribution device with a rated voltage of 400V~800V and a rated current of 100A~6000A. It has large capacity and good insulation. Strong versatility, convenient installation and maintenance, suitable for places requiring flexible power distribution.   includes laying in cable shafts of high-rise buildings to facilitate power supply to users on all floors. When the plug-in bus is laid horizontally, the distance from the ground shall not be less than 2.2m. The enclosed and plug-in bus duct is a combined structure, and the standard section is supplied by the manufacturer as a complete set (the length is generally 3m).   Various elbows and connectors are attached, and power is supplied to the electrical equipment through the switch box or fuse box attached to the plug-in bus. If the manufacturer does not supply the supporting bracket, it shall be made on site according to the design and product documents, and the bracket shall be made of section steel.   The metal shell of the busway and the plug-in box must be reliably grounded. The power system consists of several links such as power generation, transformation, transmission, distribution, and electricity consumption. Electrical engineering in industrial and civil construction projects mainly includes substation and distribution equipment, control equipment, power equipment and cables, piping and wiring, lighting appliances, lightning protection grounding devices, overhead lines and other projects below 10KV. 2. When installing and installing the low-voltage bus bar through the wall, first pre-bury the angle steel on the four corners of the hole reserved for civil construction, then weld the angle steel bracket to the pre-embedded part of the hole, and then install the insulating board (upper, The next two pieces) are bolted to the angle steel bracket.  3. Installation of busbar through wall bushing    When high-voltage lines are laid through walls, wall bushings must be used. There are two types of wall bushings: indoor and outdoor. Some are called indoor and outdoor wall bushings. When installing, first install the frame of the wall bushing in the wall hole reserved for civil construction.  After the civil works are completed, pass the wall bushings (3 in a group) into the steel plate holes in the frame, and fix them with bolts (6 sets of bolts for each group). The wall sleeve steel plate is fixed on the frame by welding along the four corners of the steel plate.   The above is the installation of the busbar, I hope it can be helpful to everyone.
