[0002] Copper busbars that can improve the flame retardant performance of insulation were first widely used in the power industry. They are also called copper busbars or copper busbars. They are made of copper material and are long conductors with rectangular or chamfered (rounded) rectangular cross-sections (now generally use copper busbars with rounded corners to avoid tip discharge). They play the role of transmitting current and connecting electrical equipment in the circuit. In the related art, copper busbars that can improve the flame retardant performance of insulation use TPE sheaths as insulating protective layers. They are put on by people, which requires a lot of manpower to assemble. In addition, the existing TEP materials have insufficient insulation and flame retardant effects, and are difficult to recycle, which is not conducive to use. Utility Model Content

To this end, the utility model proposes a copper busbar capable of improving insulation and flame retardancy, which can vulcanize the insulation protection layer and the copper busbar capable of improving insulation and flame retardancy into one piece, without the need for additional manpower assembly, and has good insulation and flame retardancy effects, and can also be recycled.

[0004] According to the first aspect of the utility model, the copper busbar capable of improving the flame retardant performance of insulation comprises a first plate and a second plate which are arranged perpendicular to each other, wherein the second plate is perpendicularly connected to the middle part of the first plate and extends to one side to form a "T" shape, and the end of the second plate away from the first plate is a conductive part, and the middle part of the second plate is integrally vulcanized and provided with an insulating protective layer, and the insulating protective layer is located between the conductive part and the connection between the second plate and the first plate.

On the other hand, the insulating protective layer and the copper busbar with improved flame retardant properties can be recycled and reused through thermal processing due to the different melting points of the insulating protective layer and the material. This reduces production costs and is beneficial to environmental protection. The insulating and flame retardant properties of the insulating protective layer make the copper busbar with improved flame retardant properties more stable, safer, and longer in service life.

[0018] Copper busbars that can improve the flame retardant performance of insulation were first widely used in the power industry. They are also called copper busbars or copper busbars. They are made of copper material and are long conductors with rectangular or chamfered (rounded) rectangular cross-sections (now generally use copper busbars with rounded corners to avoid tip discharge). They play the role of transmitting current and connecting electrical equipment in the circuit. In the related art, copper busbars that can improve the flame retardant performance of insulation use TPE sheaths as insulating protective layers. They are put on by people, which requires a lot of manpower to assemble. In addition, the existing TEP materials have insufficient insulation and flame retardant effects, and are difficult to recycle, which is not conducive to use.

It can be understood that the insulating protective layer 200 is coated on the second plate 120 by integral vulcanization molding, replacing the manual assembly method, requiring no additional manual assembly, and having good insulation and flame retardant effects. On the other hand, the insulating protective layer 200 can be recycled and utilized by thermal processing due to the different melting points of the material of the copper busbar 100 capable of improving insulation and flame retardant properties, thereby reducing production costs and being environmentally friendly. It should be noted that the insulating protective layer 200 is made of silicone products, preferably flame-retardant ceramic silicone rubber, with a flame retardant grade of UL94-V1, a temperature resistance of 105°C, pressure resistance, and no change in fire resistance. The pressure resistance requirements between the insulating protective layer 200 and the copper busbar 100 that can improve the insulation and flame retardant performance at least meet the leakage current of less than 2mA per minute at a voltage of 3700V, and the insulation resistance of the insulating protective layer 200 at a voltage of 1000V per minute is not less than 1000MΩ, thereby ensuring the insulation and flame retardancy of the insulating protective layer 200, making the copper busbar 100 that can improve the insulation and flame retardant performance more stable, safer, and longer in service life.
