In the power transmission system, the performance of equipment directly determines the stability of power supply. Corrugated bus ducts have become the preferred power transmission equipment for industrial and special environments due to their protection, wide adaptability, and reliable conductivity.
Its core structural advantages are significant: the polyester film insulation material makes the insulation resistance reach 500M Ω, and combined with direct grounding to ensure safety; The highest protection level is IP68, the shell is molded by casting, and the conductor is high-quality tin/silver plated copper bar, with excellent conductivity and corrosion resistance. This device supports high and low voltage, with a rated frequency of 50Hz, and can be customized according to needs.
The heat dissipation and high current transmission capability are its highlights. The corrugated cover plate and double-sided overlap joint design reduce thermal resistance while doubling the copper bar overlap area, resulting in better temperature rise control. The 1250A/4P model can operate for a long time at 110% of the rated voltage and has a 3750V power frequency withstand voltage performance.
Non magnetic aluminum alloy shell reduces electromagnetic interference and is suitable for environments ranging from -50 ℃ to 100 ℃; The screw free sealing structure can be used for a long time in the environment with pollution level 4, and is suitable for chemical industry, shipbuilding and other industries. Outdoor use should consider corrosion and temperature and humidity differences, and optimize temperature resistance performance.
Bus ducts need to be regularly inspected every year: power must be cut off before maintenance, and a multimeter must be used to confirm that there is no voltage before operation; Check the compliance of the load current and clean the surface dust to ensure heat dissipation; Before power transmission, it is necessary to check the insulation resistance and keep maintenance records.
The higher the protection level of the bus duct, the better. High protection will reduce heat dissipation and electrical performance. The selection should be based on the scenario, such as using IP40 grade for the distribution room, while considering fire safety requirements and usage environment.
4000A model parameters demonstrate reliability: supports long-term operation at rated current and 110% rated voltage, with a protection level of IP40; Under normal conditions, the insulation resistance of each section is ≥ 20M Ω and can withstand 3750V power frequency withstand voltage for 1 minute; Under rated current, the temperature rise of the connecting terminal is ≤ 60K, the metal shell is ≤ 30K, and the insulation component is ≤ 40K; the number of times the plug-in box is plugged and unplugged is ≥ 200 times.
Corrugated bus ducts have become the "hardcore responsibility" for power transmission with comprehensive advantages, providing safe and efficient guarantees for the stable operation of power systems in various industries.
