In modern power systems, bus ducts are an important part. Among them, high and low voltage fully insulated copper tube busbars have become the focus of the industry due to their excellent performance and technological advantages. This type of bus duct not only has a compact structure, but also has high insulation and flexible wiring methods, making it stand out among many power equipment.

1、 Structure and Characteristics

The high and low voltage fully insulated copper tube busbar adopts insulated copper tubes as conductive bars, and its design makes the busbar trunking have excellent insulation performance. In addition, it also has the following significant features:

The bus duct adopts a dense structure, which helps to improve the efficiency of power transmission and reduce line losses.

The dual connection copper bar design significantly increases the contact area of the joint, thereby reducing the temperature rise effect and enhancing the service life of the equipment.

The outer layer of the conductive strip is wrapped with flame-retardant material, which not only enhances its insulation performance, but also prevents the release of toxic gases in case of fire, ensuring the safety of use.

The flexible setting of the plug-in interface can meet various plug-in requirements, which makes the high and low voltage fully insulated copper tube busbar have the advantages of*High flexibility.

2、 Technical parameters and performance

The technical parameters and performance of the high and low voltage fully insulated copper tube busbar are also quite excellent:

The rated voltage is as high as 6.3kV, which can meet the needs of most high-voltage power systems.

The operating voltage (Um) is 7.2 kV, which allows it to withstand significant voltage fluctuations during operation.

The rated frequency is 50Hz, which complies with international standards.

The rated current is 3150A, capable of transmitting a large amount of electrical energy.

The rated thermal stability current (4s) is 40kA, which means it can withstand large current fluctuations in a short period of time.

The rated dynamic stability current (peak) is as high as 100kA, indicating its strong ability to resist short circuits.

The long-term allowable current carrying capacity of the busbar is ≤ 2.5A/mm2, ensuring stable power transmission.

The temperature rise of the rated current conductor does not exceed 40K, which means it has lower energy consumption and good heat dissipation performance.

The natural cooling method eliminates the need for additional heat dissipation equipment during operation, reducing maintenance costs.

High rated insulation level: lightning impulse withstand voltage (1.2/50ms, peak) is 75kV; 1mm power frequency withstand voltage to ground is 42kV. This ensures stable operation of the equipment in various harsh environments.

Overall, high and low voltage fully insulated copper tube busbars have become an important part of modern power systems due to their excellent performance and stability. Whether considering technical parameters, performance, or safety, it is an efficient and reliable power transmission solution.
