Low-voltage busbar trunking is a commonly utilized type of complete power transmission equipment within low-voltage power distribution systems. Featuring an entirely enclosed metal casing, they effectively block debris and prevent physical damage, thereby ensuring a high level of protection. Internally, power is transmitted via conductive busbars, resulting in a simple, orderly structure and stable operation.
Their applicable voltage range is clearly defined: an AC-rated voltage of up to 1000V and a DC voltage of up to 1500V. Their primary function is to safely and stably transmit and distribute electrical energy within low-voltage circuits， typically working together with low-voltage switchgear and power control cabinets to deliver power to different loads.
As standardized equipment dedicated to low-voltage power distribution, these systems eliminate the need for complex wiring, offer robust high-current carrying capacity, and facilitate convenient circuit branching and modification. Widely deployed across various architectural and industrial settings, they serve as a standard device for centralized power transmission and distributed power supply in modern low-voltage distribution applications.
