Problems solved by technology

[0003] However, outdoors, due to the unstable outdoor environment, the erosion of wind, rain, and sunlight will make the busway prone to failure (for example, the insulating film in the busway is easily broken and falls off, causing water to easily contact with the copper bars, which is prone to short circuits and other situations. make the busway fail)
In particular, the waterproof performance of the bus duct is poor, which limits the outdoor application of the bus duct
In addition, bus ducts used outdoors generally transmit high-voltage electricity, and the withstand voltage of bus ducts in the prior art is generally only 3-7KV, which limits the application of bus ducts in transmitting high-voltage electricity
[0004] In addition, in the prior art, the copper bars in the bus duct are often coated by manual methods, which not only makes the coating efficiency low and the cost is high, but also easily brings dust or other obstacles during the coating process, which is not conducive to The heat dissipation of the bus duct, and the sealing performance of the final film layer after coating is also poor, and water or water vapor is easy to enter, which also limits the application environment of the bus duct

The busway prepared by the preparation method of the present invention not only withstands high voltage of 10-15KV, but also has good waterproof performance, the waterproof grade can reach IP68, and good heat dissipation performance; in addition, the preparation method of the present invention does not need artificial Film coating, high production efficiency and low production cost.

Description

technical field [0001] The invention belongs to the field of power transmission trunk lines, and in particular relates to a high-pressure-resistant and waterproof busway and a preparation method thereof. Background technique [0002] The bus duct is a power transmission device, generally composed of copper bars and a protective insulating film covering the surface of the copper bars after assembly. Since the busway has obvious power supply advantages in terms of high voltage and high power, it has gradually replaced traditional wires and cables as a power transmission trunk line indoors. It has been popularized in developed countries abroad, as well as Hong Kong and Macao in my country. In Guangzhou, Guangdong, where the power distribution room of buildings with more than 12 floors goes out, more than 90% of the main lines leading to the floors use bus ducts; 630KVA transformers also use bus ducts to power distribution cabinets. [0003] However, outdoors, due to the unsta...
