Busway way through the inner conductive insulator 2-7 root conductive copper, using air-insulated manner, a lighting and power (220V & 380V) separate shunt control. The mobile power supply to provide power socket (220V & 380V) is slidable within the through-the entire working power busbar to an arbitrary position and may be increased or decreased at an arbitrary position of the feeding point. Carbon brushes for electric shock to the socket while the power situation can be avoided due to the sliding outlet sparks, eliminate safety hazards. Busway normal use of tenders (4 m / root) docking mode installation, use and maintenance overhaul process is very simple, convenient, Busway line for subsequent movement and transformation reusable, no consumption. The new look for the lighting power busway as a new power supply is gradually replacing the traditional cable tray, it is secure, reliable, flexible, installation, maintenance is convenient, neat appearance, characteristics and generous with generally accepted by the majority of users.
