A brief introduction to dense busbars

Dense busbars are a form of electrical power transmission using copper or aluminum bars. Do you know why dense busbars are needed? We use dense busbars because ordinary cables have insufficient current-carrying capacity. Flat cables are insufficient to meet the current-carrying capacity requirements, hence the use of dense busbars. With the advent of modern engineering facilities and equipment, electricity consumption in various industries has rapidly increased, especially with the emergence of numerous high-rise buildings and large factories. Traditional cables, as transmission conductors, cannot meet the requirements of high-current transmission systems. The parallel use of road cables brings many inconveniences to on-site installation and construction connections. Dense busbars, as a new type of power distribution line, have emerged as a solution.

Introduction to and Applications of High-Voltage Busbars

High-voltage busbar applications include electrical connections between transformers and high-voltage switchboards, power supply systems in large factories and mines, large substations, and the electrical connections between generators and step-up transformers in large enterprises' self-owned power plants. Generally speaking, busbar systems with operating voltages above 3000 volts are called high-voltage busbars. The interphase insulation resistance of high-voltage busbars must be greater than 1000M ohms. High protection level, generally IP54 outdoors. High-voltage busbars are used in connection with power plants and large transformers. High-voltage busbars adopt a high-strength, high-performance DMC insulation block clamping structure, with good load performance and dynamic and thermal stability; strong overload capacity and low temperature rise. High-voltage busbars adopt a closed-type encapsulation, which can greatly reduce the number of power outages for maintenance and repairs; when transmitting large currents, it can eliminate faults caused by unbalanced current distribution due to the use of double-spliced or triple-spliced high-voltage cables. High-voltage busbars are easy to install and can be adjusted in two degrees of freedom in the horizontal and vertical directions. They can not only meet the expansion and contraction requirements caused by different temperature drops and thermal expansion and contraction, but also compensate for errors caused by foundation settlement, solving the problems of poor protection level, troublesome installation, and unreliable operation of traditional slider-type expansion devices. Guangzhou Tianqin Electrical Equipment Co., Ltd. is located next to Shapu Lixin Highway in Xintang Town, Zengcheng District, Guangzhou City (opposite Zengcheng Guangben Factory). The company focuses on the R&D, production, sales, and installation of busbar products, providing comprehensive services for busbar distribution systems, and providing busbar distribution system products and engineering services to numerous enterprises.

Basic Introduction to Busbars

Busbar trunking, refers to an enclosed metal device made of copper and aluminum busbars, used to distribute large power to various components of a dispersed system. The features of busbar trunking include series matching, commercial production, small size, large capacity, short design and construction cycle, easy installation and removal, non-combustibility, safety and reliability, and long service life. Busbar trunking products are suitable for three-phase four-wire and three-phase five-wire power distribution systems with AC 50Hz, rated voltage 380V, and rated current 250A-4000A. Insulation support is a component of the busbar trunking equipment, used to support the conductors in the busbar trunking equipment. Mounting plates are used to support various components and are suitable for mounting in complete sets of equipment. Mounting frames are used to support various components and are suitable for mounting in complete sets of equipment. Enclosure: The enclosure protects the equipment from certain external factors and prevents direct access to the equipment in all directions. Its protection level is at least IP30. Door: A hinged or sliding cover plate. Cover plate: The upper and lower shell surfaces of the enclosure, usually a component on the busbar trunking equipment, is used to cover the openings on the enclosure. It is fixed with screws or similar methods, and generally not removed after the equipment is put into operation. Side plate: The left and right shell surfaces of the enclosure, usually a component on the busbar trunking equipment, is used to cover the openings on the enclosure. It is fixed with screws or similar methods, and generally not removed after the equipment is put into operation. Insulation partition: A component used to protect against direct contact from all directions at the entrance and from arcs from switching devices and similar devices. Live part: Conductors or conductive parts energized during normal use, including the neutral conductor, but not including the neutral protective conductor. Exposed conductive part: An accessible conductive part of an electrical equipment, usually not energized but may be energized in case of fault. Protective conductor: A conductor electrically connected to the following parts to prevent electric shock hazards. Special note: Cables are indicated by cross-sectional area, and busbar trunking is indicated by rated operating current (generally referred to as 400A busbar trunking). Similarly, domestic products with 400A have a cross-sectional area of 240mm, while some are only 180mm. Guangzhou Tianqin Electrical Equipment Co., Ltd. is located beside Shapu Lixin Highway, Xintang Town, Zengcheng District, Guangzhou City (opposite Zengcheng Guangben Factory). The company focuses on the R&D, production, sales, and installation of busbar trunking products, providing comprehensive services for busbar trunking power distribution systems, and providing busbar trunking power distribution system products and engineering services for numerous enterprises.
