Electrical Aluminium Bus Duct System Busbar Trunking Copper Plastic Insulated Enclosure

Product Description:

The dynamic stability of the busbar means that when a short circuit occurs, a large surge current will flow through the busbar and generate a huge electric force. When the mechanical strength of the busbar and post insulators is insufficient, deformation or damage accidents may occur. When a three-phase busbar arranged in the same plane experiences a symmetrical short circuit, the middle phase bears the maximum electric force, and the maximum value of the short-circuit electric force occurs at 0.01S after the short circuit. Therefore, the dynamic stability of the busbar is usually tested according to the three-phase short circuit condition. The maximum stress that the busbar can withstand under this maximum electric force should be less than the allowable stress value of the busbar material.

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.
