Description

Technical Field

It can supply power to specific equipment through matching plug-in boxes and other devices. Especially in the power supply of network cabinets in data centers, the terminal busbar power supply method has increasingly replaced the traditional cable power supply method of the head cabinet. This power supply method can provide a large power output capacity and has a strong expansion capability. At the same time, it also saves precious space resources after replacing the head cabinet, allowing users to deploy more network cabinets. The characteristics of the terminal busbar are series matching, commercial production, large capacity, short design and construction cycle, easy installation and disassembly, no burning, safe and reliable, and long service life.
