5000A semi insulated tubular bus ductIt is a type of power equipment used for high-voltage and high current transmission, mainly composed ofHigh purity copper tubeoraluminum tubeAs a conductor, it is wrapped in multiple layers externallySemi insulating composite material(such asepoxy resin、cross-linked polyethyleneEtc.) to form a closed structure.

In the field of power equipment today, semi insulated tubular bus ducts have been widely welcomed for their advantages and processes. The busbar duct is not limited by the board material and adopts a tile groove type shell design, which not only increases the mechanical strength of the busbar, but also ensures the ability to produce horizontal sections of the busbar up to 13m in length.

In terms of material selection, the T2Y cold drawn copper tube is the core part of the busbar trunking. Compared with copper pipes produced by small factories in a semi-solid state, T2Y pipes produced by domestic large factories (such as Luoyang Copper) in a cooled state have higher quality. Experimental data shows that pipes with the same cross-section have a temperature rise difference of only 3-6 ℃ under the same rated current, which further proves their excellent conductivity.

The main insulation material F4, also known as polytetrafluoroethylene, has many domestic manufacturers, but there are significant differences in product quality. In order to ensure the insulation performance of the bus duct, we specially selected F4 produced by Jinan Sanai, whose particles are imported materials provided by Daikin Corporation of Japan. This material performs well in insulation strength, temperature coefficient, and other aspects, providing strong guarantees for the excellent performance of the product.

Strengthening insulation treatment is a key step in improving product performance. During the production process, we optimize the surface electric field of the tube to ensure that the temperature rise is within a reasonable range. After repeated testing and verification, our company's tubular insulated busbar performs excellently: the 10kV product does not breakdown or flashover under 75kV withstand voltage, and both partial discharge and dielectric loss meet the standards; And 35kV products also perform well under 105kV withstand voltage. This result is significantly better than similar domestic products, further proving our professional technical strength.

The selection of connectors is also crucial. To solve the problems caused by traditional external connectors, we have innovatively adopted embedded connectors. This design is not only easy to connect and has a large contact area, but more importantly, it has a beautiful appearance and easy operation. It avoids the formation of bubbles and partial discharge points in raised areas, ensuring long-term stability and reliability during operation.

In conclusion,5000A semi insulated tubular bus ductWith its excellent performance and craftsmanship, it meets various environmental and application requirements. It is an ideal power transmission solution for places such as homes, schools, businesses, and municipal engineering. In the future, we believe that semi insulated tubular bus ducts will continue to leverage their advantages and make greater contributions to the development of the power industry.
