3200A semi insulated tubular busbarAs an electrical equipment that plays an important role in the power system, it is widely used in multiple fields due to its unique performance characteristics. Understanding its characteristics and application scenarios is of great significance for the stable operation and rational planning of the power system.

Advantages of semi insulated tube busbar:

1. Electrical performance

-High current carrying capacity: The semi insulated tube busbar adopts a special structural design, and the conductor is usually made of high conductivity copper or aluminum material. Its circular cross-sectional structure makes the current distribution more uniform, reduces the influence of skin effect, and thus can carry larger currents than traditional busbars under the same cross-sectional area. This feature gives it significant advantages in high-capacity power transmission and distribution scenarios.

-Good insulation performance: Although it is called semi insulation, it still has reliable insulation performance. The insulation material used has high insulation resistance and voltage resistance, which can effectively prevent the occurrence of leakage and breakdown phenomena. Under normal operating conditions, it can ensure the safety and stability of power transmission, and reduce the probability of faults caused by insulation problems.

-Low electrical loss: Due to the excellent material and reasonable structural design of the conductor, the semi insulated tube busbar has relatively low resistance loss during the transmission of current. At the same time, the dielectric loss of its insulation material is also relatively low, which effectively controls the electrical energy loss of the entire busbar system and improves energy utilization efficiency.

2. Reliable mechanical performance

-Sturdy structure: The tubular structure endows the busbar with high mechanical strength. It can withstand certain external impacts and vibrations, and is not easily deformed or damaged. In harsh environmental conditions, such as strong winds, earthquakes, and other natural disasters, a stable structure can still be maintained to ensure the continuity of power transmission.

-Strong anti fatigue performance: During long-term operation, the busbar will be affected by the electric force generated by current changes and environmental factors. The semi insulated tube busbar has excellent fatigue resistance through optimized material selection and manufacturing processes, and can maintain stable performance and extend service life under repeated stress.

3. Good heat dissipation performance

The tubular structure provides a large heat dissipation area for the busbar. Compared with traditional rectangular busbars, semi insulated tube busbars can dissipate the heat generated during operation more quickly to the surrounding environment, effectively reducing the temperature of the busbar. Good heat dissipation performance not only helps to improve the current carrying capacity of the busbar, but also reduces insulation aging and performance degradation caused by overheating, ensuring the long-term stable operation of the busbar.

4. Easy installation and maintenance

-Easy installation: The structure of the semi insulated tube busbar is relatively simple, lightweight, and does not require complex lifting equipment or a large amount of manpower during installation. Its standardized design makes the installation process more standardized and efficient, greatly reducing the installation cycle.

-Low maintenance cost: Due to the use of reliable insulation materials and sturdy structure, the failure rate of semi insulated tubular busbars is relatively low. The daily maintenance work mainly includes simple items such as appearance inspection and insulation resistance testing, and the maintenance cost is relatively low.

Tube type conductors are generally installed overhead after welding, using tube busbar fittings for fixation. Due to the reduced strength at the joint after welding (about 65% of the base material), in order to avoid bending at the joint during use, a lining tube should be used for reinforcement inside the joint. There should not be more than two welding joints between two empty pillars (or suspension points). The commonly used welding methods for aluminum and aluminum alloy tubes areArgon arc welding, also known as argon arc welding, is a direct current welding power source that uses a welding wire (or welding rod) as an electrode under argon protection to generate an arc with the workpiece. The welding is carried out at the interface between the welding wire (or welding rod) and the workpiece. Its advantages include heat concentration, stable arc, and good protection of the molten metal by argon gas to prevent oxidation. It can also remove the oxide film on the surface of the molten metal through argon arc welding. Therefore, it can obtain welds with fewer defects and purity, and can easily master welding techniques and perform all position welding.
