A cabinet is the "house" of electrical equipment. Whether it is solid, leaks, gets hot or can be moved whole depends on a few basics: IP rating, load, cooling and form. Below we explain the highest-frequency concepts; follow the links for deep dives.
Dust and water resistance; higher number = harsher environment.
Static and dynamic capacity of frame and shelves.
Natural convection, forced air, heat exchanger.
Floor cabinet, wall cabinet, container room.
First digit = dust (0-6), second = water (0-8). IP54 limited dust + splash, for most indoor electrical. IP65 full dust + spray, for outdoor, humid, dusty. Pick by environment: indoor distribution IP54 is enough; outdoor or washdown IP65, with gaskets and roof.
| Rating | Dust | Water | Use |
|---|---|---|---|
| IP30 | solid>2.5mm | none | clean indoor |
| IP54 | limited dust | splash | indoor electrical |
| IP55 | limited dust | spray | semi-outdoor |
| IP65 | full dust | spray | outdoor, dust, washdown |
Load splits into static (settled equipment weight) and dynamic (transport, lift, quake). Calculate shelf thickness, stiffeners, frame section and total rating, and consider center of gravity and transport fixing. Heavy racks and distribution cabinets must be calculated clearly.
Heat leaves three ways: natural convection (vents, fins), forced air (fans, ducts) and heat exchanger / AC (sealed high power). Balance protection vs intake: an IP65 sealed cabinet uses a heat exchanger rather than holes. We build ducts, fins and exchanger mounts by power and IP.
A container room integrates distribution, control, storage or equipment in a standard box — good for temporary power, sites, mining and overseas. Choose by size, protection/insulation, internal trays, layout and transport; keep service aisle, intake/exhaust and earthing.
Flexible, good for shapes and small batches, clean edge, low burr — the mainstream.
Fast and cheap for high-volume standard hole patterns; limited on shapes.
Rule: shapes, small batches, high edge quality → laser; high-volume standard holes → turret punch is cheaper. Xingyuan runs laser-primary with CNC punch as support.
Dust: IP54 limited, IP65 full. Both resist spray (second digit 5), but IP65 is cleaner on dust — better for dusty/outdoor. Outdoor prefers IP65.
Static weight sets shelf/frame load; add dynamic factor for transport/lift/quake to set thickness and stiffeners. For heavy cabinets, send equipment weight for our calculation.
Sealed cabinets avoid holes; use a heat exchanger or AC to move heat out; low power can use natural convection with fins.
Size, protection/insulation, internal trays, layout and transport; reserve service aisle, intake/exhaust and earthing.
Shapes, small batches, edge quality → laser; high-volume standard holes → turret punch. Xingyuan runs laser-primary.
Yes. Send drawings or a list; our engineers advise selection and sheet metal by environment, load and cooling.
