The copper busbar size design in the switch cabinet should follow the following principles:
Design drawings and technical agreements: First, the copper busbar size should be selected according to the drawings and technical agreements provided by the design institute. If there are specific requirements in the drawings or agreements, the design should be strictly in accordance with these requirements.
Reference to standard data: If there are no specific requirements, the appropriate copper busbar size can be selected by referring to the relevant standard data.
Voltage level and connection group: The size of the copper busbar should also consider the voltage level and connection group of the switch cabinet. For example, for the voltage level of 10/0.4kV, the appropriate copper busbar size should be selected.
Current carrying capacity considerations: The current carrying capacity of the copper busbar is an important basis for selecting busbar specifications, and the appropriate copper busbar size should be selected according to the current carrying capacity of the low-voltage switch cabinet.
Busbar direction and size: The direction and size of the busbar should be determined by the constructor, and ensure that the wiring of the switch cabinet of the same form is consistent.
