Galvanized Steel Electrical Enclosure Indoor Power Distribution
Cabinet
Product Describe:
1. Galvanized steel control boxes are widely used in the following
scenarios:
2. Industrial automation: Mounting PLCs, relays, and motor
controllers in factory environments with moderate humidity and dust
levels.
3. Power distribution systems: Low-voltage switchgear and meter
cabinets for commercial buildings and residential complexes.
4. HVAC systems: Housing control panels for air conditioning units,
ventilation systems, and heating equipment.
5. Transportation infrastructure: Railway signal control boxes,
highway toll station electrical enclosures, and parking lot
management systems.
6. Agricultural facilities: Irrigation control systems and
livestock farm electrical distribution boxes (indoor or sheltered
outdoor use).

IP Rating:
| IP Rating | Protection Capability Description | Application Scenarios | Special Requirements |
|---|
| IP55 / IP65 | Dustproof + Waterproof | Outdoor / Indoor | Full weld seams required, surface powder coating or surface brushing treatment |
Suggestion:
1. Sealing treatment: EPDM foam rubber strips are used at the door
seams (cross-sectional diameter ≥8mm, compression amount 30%),
nylon waterproof joints are equipped for incoming and outgoing wire
holes (IP68 rating, thread specifications M20-M63 optional), and a
5° inclined drainage groove is reserved at the bottom.
2. Heat dissipation design: A temperature-controlled heat
dissipation system is configured when the internal temperature is
>40°C: ① Natural heat dissipation (ventilation hole area ≥0.05m², upper and
lower convection layout); ② Forced heat dissipation (12V silent fan + dust filter, air volume
≥80m³/h); ③ Heat pipe heat dissipation module is used in special environments.
3. Anti-corrosion treatment: In addition to basic galvanizing, the
following can be added: ① Phosphating + electrostatic spraying (film thickness 60-80μm, color
customized according to RAL color card); ② Stainless steel edge wrapping (304 material, used for
anti-collision of box corners); ③ Internal color galvanizing.
