Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of enclosed busbars, it is recommended to screen based on key technical parameters such as current capacity, insulation level, and protection type to ensure compatibility with the power distribution system.
  • In high current application scenarios such as industrial plants or data centers, the heat dissipation performance and structural strength of enclosed busbars are key factors affecting long-term stable operation.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • When purchasing enclosed busbars, it is necessary to consider the space limitations of the installation environment and pay attention to whether their modular design is convenient for on-site splicing and later maintenance.

Knowledge Base

Q

The selection of models for enclosed bus ducts requires consideration of multiple factors. The first thing to consider is the rated current. Select the appropriate rated current bus duct model based on the actual load current. If the load current is high, it is necessary to choose a bus duct model with a corresponding high rated current to ensure that it can carry normal load current without overheating or other problems. Secondly, the busbar should be considered

Q

The insulation resistance of a closed bus duct refers to the resistance value between the internal and external metal shells of the bus duct under a certain voltage. The size of the insulation resistance reflects the insulation performance of the bus duct, that is, whether there is a risk of leakage or electric shock between the internal wires and the metal shell. Normally, the insulation resistance of enclosed bus ducts should reach a certain value to ensure their safe and reliable transmission
