Problems encountered when purchasing low-voltage distribution cabinets
Thread Content
I would appreciate some advice from experts. My company needs to purchase a batch of low-voltage distribution cabinets, and I want to know what data we need to provide to the manufacturers in order for them to be able to produce these cabinets
Aren’t the aunts here? Someone who knows well about such things, please help me
First, determine the specification and model of the low-voltage switchgear – whether it is a drawer-type cabinet or a fixed-type cabinet； Once again, the various technical parameters of low-voltage switchgear, rated current, branch circuits, low-voltage distribution system diagrams, and low-voltage control schematics ； Only at the end were some specific technical requirements proposed.
First, select the cabinet type you desire; once the system diagram and schematic provided by the design team have been approved, they are sent to the cabinet manufacturer. The specifications for other components and materials can be outlined in the technical agreement.
Actually, you can make it simpler: just find the manufacturer and ask them what documents are needed. Some manufacturers can also provide the schematic diagrams.
The drawings indicate the load capacity and voltage level. They also specify the models of various key components such as knife switches, circuit breakers, contactors, thermal relays, capacitors, soft starters, frequency converters, etc. The cabinet type, dimensions, and quantity are indicated according to the cabinet number. Please also note the brand of attachments such as fuses, meters, and transformers; it is optional to include the model numbers. We recommend that the manufacturer provide the drawings, and you can then review them. Remember to provide a detailed quote; avoid giving a full-container quote, as it lacks comparability for reference.
