Mild Steel Electrical Enclosure Industrial Commercial VFD Control Cabinet
Product Describe:
1. Indoor industrial control systems: Housing low-voltage components like contactors, relays, or PLCs in dry workshops or factories, where corrosion risks are minimal.
2. Building electrical distribution: Used as junction boxes or meter cabinets in indoor settings (e.g., basements, utility rooms) to protect wiring and electrical meters.
3. General-purpose storage: Enclosing non-critical equipment such as small pumps, fans, or lighting controls in warehouses or commercial facilities.
4. Low-humidity environments: Suitable for indoor telecom rooms or office building weak current cabinets, where minimal exposure to moisture or chemicals ensures durability.

Suggestion:
Clarify functional needs: Prioritize heat dissipation for high-power equipment; enhance IP rating for outdoor use to resist dust and water.
Define dimensions: Size based on installation space and internal components. Opt for compact wall-mounted designs for narrow areas or larger floor-standing models for more elements, with extra space reserved for future expansion.
Optimize structure: Ensure cabinet doors open to ≥90° for easy maintenance. Add lifting holes or handles for handling; design suitable structures for side-by-side installation if needed.
Material details: Choose mild steel thickness (1.0–2.5mm) based on load and vibration—thicker plates for heavy components or high-vibration environments. Consider galvanizing to boost corrosion resistance.
Surface treatment: Use epoxy powder coating (80–100μm thick, baked at 180–210°C) with non-glare textures (e.g., smooth/fine patterns).
EMC considerations: Adopt grounding, shielding, and filtering. Use conductive gaskets for seams, shorten screw spacing, and add shielding nets for vents/observation holes.
Internal layout: Separate high-voltage (contactors, relays) and low-voltage (sensors, controllers) components to reduce interference. Ensure safe distances for wiring and maintenance.
Accessories: Select locks, hinges, gaskets, and handles. Locks should offer security; gaskets improve protection against dust/moisture.
