Answer:

First, the lighting busway, for garage lighting, is the finished product installation is very convenient, there is no fixed number can be set, similar to the closed bus, you can borrow, its built-in core insulation line. Second, the characteristics: lighting busway system with small size, strength, easy installation and so on. Applicable to A various places such as fluorescent lamps, tribute lights and other lighting equipment for power distribution. It is a combination of different locations of the site, the installation is simple and quick.
But I do not know how to make clear from the three ends of the three-phase winding leads to three lines called the phase line from the star-connected three-phase winding neutral point N leads the wire Called the neutral line at each end of the winding voltage is called the phase voltage is usually specified from the beginning to the end of the voltage in the positive direction. The voltage between the phase and phase lines is called the line voltage. The voltage across the coil is called the phase voltage. Usually denoted by UA, UB, and UC, respectively. The voltage between the end line and the end line is called the line voltage. Generally used UAB, UBC, UCA said. Where the current flowing through each phase of the phase phase current, flow through the end of the current line called current.
