The Bus duct system is a Bus duct transmission and distribution system specially developed by Shanghai Zhenda to meet the market demand and the current market demand. The design current is 100A-6300A. It is suitable for residential buildings, business office buildings, large shopping malls and other places. The design is advanced. Its special shell structure can effectively solve the system high temperature caused by its own heating. It is equipped with an intelligent monitoring system, Effective real-time monitoring of system operation status. The product itself adopts green and energy-saving treatment from materials to production processes, greatly saving energy consumption.

Cable trays are divided into slot type cable trays, tray type cable trays, step type cable trays, molded cable trays, and other structures, consisting of brackets, brackets, and installation accessories. It can be erected independently or laid on various buildings (structures) and pipe rack supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts need to be galvanized and installed on the outdoor bridge outside the building. If it is located near the seaside or in a corrosive area, the material must have anti-corrosion, moisture resistance, good adhesion, and high impact resistance characteristics.

The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box), and is the final level equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in situations where the load is relatively dispersed and there are fewer circuits; The motor control center is used in situations with concentrated loads and multiple circuits. They distribute the electrical energy of a certain circuit of the upper level distribution equipment to the nearby load. This level of equipment should provide protection, monitoring, and control for the load.

The connection of high-voltage distribution equipment in Electrical substation, as well as the connection of electrical equipment such as transformers and corresponding distribution equipment, mostly adopts bare conductors or stranded wires with rectangular or circular cross-section, which are collectively referred to as buses. The function of a busbar is to collect, distribute, and transmit electrical energy. Due to the enormous amount of electrical energy passing through the busbar during operation, it bears significant heating and electrodynamic effects during short circuits. Therefore, it is necessary to choose the busbar material, cross-sectional shape, and cross-sectional area reasonably to meet the requirements of stable and economic operation<

Busbars are divided into hard busbars and soft busbars according to their structure. Hard busbar is further divided into rectangular busbar and tubular busbar<

Rectangular busbar is generally used from the main transformer to the distribution room, with the advantages of convenient construction and installation, small changes in operation, large carrying capacity, but high cost<

The flexible busbar is used outdoors, and due to the large space, the swing of the wires does not cause insufficient distance between the wires. Soft busbar construction is simple and cost-effective.

The advantages and characteristics of prefabricated supports and hangers are that compared with traditional cylindrical spiral assembly materials, prefabricated supports and hangers reduce costs, have more reasonable structural design, stronger self weight, and better installation and debugging quality. This new type of support and hanger integrates the locking system, limit system, and protection system, making it convenient for on-site installation and debugging. The use of elastic components can increase the applicability of supports and hangers, thereby improving the performance of the entire equipment. Therefore, reliable service institutions are more worthy of selection<

Assembled supports and hangers with smaller size and lighter weight have a wider range of applications and lower costs during use, making them a highly favored support and hanger product. Choosing from merchants can lead to better quality and excellent support for various pipeline installations. Therefore, a more scientific method of selection will definitely gain the trust of more customers.

Pipe gallery support, i.e. the corridor of the pipeline. Many pipelines in chemical and related factories are concentrated together, arranged along the equipment or outside the factory building, usually in the air, supported by brackets, forming a similar appearance to corridors. There are also a few pipe galleries located underground<

The pipe rack bracket is generally an open type structural component used for supporting overhead pipeline laying above ground. The main location for centralized laying of large equipment pipelines is composed of steel or reinforced concrete columns, beams, and trusses, which can be divided into single or multiple layers, accessible or non accessible according to type.
