Functional unit: 1. Direct unit: Feed type direct unit with a specification length of 0.5~3.0m, set sensitively, and can meet the installation requirements inside the wind tower. 2. Initial incoming unit: transitional connection between supply and incoming/outgoing cables; 3. Bus section joint connector: The connection of the bus duct joint adopts an integral special joint connector. The joint connector uses low-temperature resistant alloy steel torque bolts, and the compression bowl gasket is a wide edge large gasket made of manganese alloy to ensure uniform and reliable pressure on the entire compression surface; The connector is equipped with temperature display installation, so that users can timely understand the operation status of the bus duct and handle special situations; It can be ensured that a section can be removed without affecting adjacent busbars, and the connection point can also be removed when electrical insulation is required for on-site maintenance or modification. Each connector can effectively absorb the thermal expansion and contraction of the conductor (can be used as a+/-5mm conditioning). 4. Elastic support: Choosing elastic support as the busbar installation bracket can effectively eliminate the influence of tower bracket errors and wind tower vibrations on the busbar trough.

Advantages: ◆ High rated current up to 12000A, especially suitable for circuits with high working current ◆ Low skin effect, low power loss. The skin effect coefficient of insulated busbars is low, Kf≤1， The communication resistance is small, so the power loss of the busbar is small. The busbar with good insulation performance adopts sealed shielding insulation method, and the grounding potential of the shell is zero. The insulated tube type busbar with shielding has uniform electric field distribution and strong electrical insulation performance. It can be directly passed through cable trenches and cable interlayers. The main body of the busbar has high mechanical strength, allowing for a stress four times that of a rectangular busbar. It can withstand high short-circuit currents and has high mechanical strength, which increases the support span of the busbar. ◆ Good heat dissipation conditions and low temperature rise. The busbar is a hollow conductor, and the inner diameter air duct of the busbar can naturally form hot air convection (due to the pressure difference between indoor and outdoor), with good heat dissipation conditions. ◆ The main insulation material of the busbar with high heat resistance coefficient is polytetrafluoroethylene, which can work in -250 ℃ -+250 ℃, has excellent electrical performance and chemical stability, low dielectric loss, flame retardancy, aging resistance, and a service life of ≥ 40 years. ◆ Strong resistance to electrical vibrations can be achieved by directly fixing the busbar on a steel frame or concrete support, eliminating the need for through wall sleeves and post insulators, and possessing strong resistance to vibrations.

When installing metal cable trays vertically or obliquely, measures should be taken to prevent wires or cables from moving in the slots. 2. All phase and neutral wires of the same circuit should be placed in the same metal trunking. 3. The trunking of tubular busbars is suitable for indoor drying in normal environments and places that are not easily damaged by machinery, but should not be used in places where the metal trunking is severely corroded. 4. The lines drawn in metal cable trays can be wired, such as metal pipes, hard plastic pipes, semi-rigid plastic pipes, metal hoses, or cables. The lead out part should not damage the busbar or cable. 5. The tubular bus duct should be grounded or reliably grounded, but should not be used as a grounding wire for equipment. 6. The lines should be smooth and not deformed, and the inner wall should be smooth and free of burrs.

Compared with various accessories for wiring and the entire power system, using bus ducts can make the construction cost much cheaper (please see the diagram), especially for plug-in bus duct manufacturers with large current capacity. This situation is even more obvious. With the emergence of modern engineering facilities and equipment, the electricity consumption of various industries has increased rapidly. The specification of plug-in bus ducts, especially the emergence of numerous high-rise buildings and large factory workshops, traditional cables as transmission conductors can no longer meet the requirements in high current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections. Plug in busbar trunking, as a new type of distribution wire, has emerged. Due to the use of copper sheet soft joints for transition between busbars, oxidation is prone to occur between joints in humid weather in the south, resulting in poor contact between joints and busbars, making the contacts prone to heating. Therefore, it is rarely used in the south. And the volume between the joints is too large, the horizontal bus segment size is inconsistent, and the appearance is not aesthetically pleasing. According to the insulation method, it can be divided into three types: air type plug-in bus duct, dense insulation plug-in bus duct, and high-strength plug-in bus duct. Due to the use of copper sheet soft joints for transition between busbars, oxidation is prone to occur between the joints in humid weather in the south, resulting in poor contact between the joints and busbars, making the contacts prone to heating. Therefore, it is rarely used in the south. And the volume between the joints is too large, the horizontal bus segment size is not aesthetically pleasing.

Nine advantages of busbar system: 1. Meeting load requirements, dense busbar trunking specifications, 100A-6300A2, anti-corrosion, moisture-proof, dustproof, and waterproof four protection functions, with a protection level of up to IP65, non-magnetic shell design, eliminating magnetic eddy interference. 4. The sub shaped structure is thinner and better. 5. The busbar trunking can form a 360 degree protection. 6. Double grounding system, dense busbar trunking function, * shielding magnetic field, safer electricity use. 7. Two page (riveted) assembly, sandwich structure design, withstand strong mechanical impact. 8. The appearance adopts heat sink design, low temperature rise, low consumption. 9. Can monitor temperature rise
