Product Description:

The thermal stability of the busbar means that during a short circuit, a large amount of heat is generated inside the conductor, which cannot be dissipated into the surrounding air in time, causing the temperature of the conductor to rise rapidly. Due to the short duration of the short circuit, its allowable temperature should be much higher than the allowable temperature for heating during long-term operation The allowable heating temperatures for copper and aluminum bare busbars during short circuit are 300 degrees and 200 degrees, respectively. When selecting a busbar, the short-term heating temperature calculated during the short-circuit transient process of the busbar should be lower than the allowable short-term heating temperature on the actual busbar.

Features:

1. High safety and reliability: The fully enclosed design effectively prevents accidental electric shock to personnel, and the protection level can reach IP40 or above. Using high-quality insulation materials, the insulation resistance is high (normal ≥ 20M Ω, still ≥ 100M Ω at 100 ℃). Equipped with reliable grounding devices, it can quickly lead into the ground in case of leakage, ensuring personal safety.

2. Large transmission capacity: The conductive busbar has a large cross-sectional area, low resistance, and can carry larger currents (up to 6300A). The metal shell has good heat dissipation performance, which can timely dissipate working heat and ensure stability during long-term high current operation.

3. Easy installation and maintenance: Modular design enables quick and convenient connection between various bus duct units, reducing installation time and labor intensity. The plug-in box combination power supply method allows for the adjustment of the position of electrical equipment without the need to change the power supply system, only the plug-in interface needs to be adjusted.

4. Good economy: Although the initial investment is high, the long-term maintenance cost is 50% lower. The factory's complete production quality is guaranteed, with higher precision and better consistency compared to on-site production, reducing construction and installation workload.

5. Strong environmental adaptability: capable of working in a wide temperature range from -40 ℃ to+70 ℃, adaptable to various climatic conditions. It can maintain stable performance under mechanical stresses such as vibration and impact.
