Carrying capacity is big
The main body of the tubular busbar is aluminum alloy tube, with a large surface area. Compared with the conventional rectangular busbar, the current density on the surface of the conductor is evenly distributed, and the highest rated current is up to 12000A.
Good insulation
The Tube Bus Tubular Aluminum Bus is insulated by sealing and shielding, the grounding potential of the shell is zero, the electric field on the bus surface is evenly distributed, and the electrical insulation performance is strong.Can be directly through the cable trench and cable sandwich.
High mechanical strength
The allowable stress of the main body of the tubular bus is 4 times of that of the rectangular bus, which can stand large short-circuit current and high mechanical strength, making the maximum span of the bus support up to 8 meters.
Good heat dissipation and low temperature rise
The tubular bus is a hollow conductor, and both ends of the bus are provided with ventilation holes. The inner diameter air duct can naturally form hot air convection, and the condition of heat dissipation is better than that of the conventional bus.
Low loss
The shape of the tubular bus determines that its surface skin effect coefficient is low, Kf≦1, and the ac resistance is small, so the power loss of the bus is small.The dielectric loss of the insulating layer of the cross-linked shielding insulated bus is less than 0.01%.
Insulation material has high heat resistance
Crosslinking shielding tubular busbar insulation main insulation material is ptfe, has excellent electrical properties and chemical stability, can be in 200 ℃ ~ + 200 ℃ to work properly, small dielectric loss, flame retardant, resistance to ageing, cooperate with other insulating materials, the use of the product life ≧ 30 years.
No environmental interference, high reliability
Bus structure is simple, clear layout, easy installation, less maintenance work.
