The bus duct is a new circuit method developed in the United States called "Bus-Way-System" made of metal plates (steel plates or aluminum plates). It is a bus system composed of protective shells, conductive bars, insulating materials and related accessories. .It can be made into a plug-in closed busbar with plug-in junction boxes at regular intervals, or a feed-type closed busbar without a junction box in the middle.In the power supply system of high-rise buildings, power and lighting lines are often set up separately. The bus duct, as the main power supply line, is installed vertically along the wall in one or more passes in the electrical shaft.
The bus duct is characterized by a series of supporting products, commercial production, small size, large capacity, short design and construction period, convenient assembly and disassembly, no burning, safety and reliability, and long service life.Bus duct products are suitable for three-phase four-wire and three-phase five-wire power supply and distribution system projects with AC 50Hz, rated voltage 380V, and rated current 250A-6300A.
Baoliwei Electric Beijing Co., Ltd. is a modern enterprise specializing in the production of various types of high and low voltage bus ducts, cable trays, distribution boxes and other power transmission and distribution equipment. We believe that with the emergence of modern engineering facilities and equipment, all walks of life Electricity consumption is increasing rapidly, especially with the emergence of many high-rise buildings and large factories and workshops. Traditional cables as transmission conductors can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables has brought difficulties to on-site installation and construction connections. Due to many inconveniences, plug-in bus duct emerged as a new type of distribution conductor.
Compared with traditional cables, its superiority is fully demonstrated when transmitting large currents. At the same time, due to the adoption of new technologies and new processes, the contact resistance at the connections at both ends of the bus duct and at the branching port is greatly reduced. and temperature rise, and uses high-quality insulation materials in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more complete.
Bus ducts have increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects.It has become popular in developed countries abroad, as well as Hong Kong and Macau in my country.In Guangzhou, Guangdong, my country, bus ducts are used for more than 90% of the main lines leading to the power distribution rooms of buildings with 12 or more floors; bus ducts are used from 630KVA transformers to distribution cabinets.The use of bus ducts is also popular in public construction projects, hotels, and office buildings in large and medium-sized cities. Bus ducts are the best choice for indoor power transmission trunk lines with rated voltages below 1000V.
