Galvanized Steel Electrical Enclosure Box Indoor Power Distribution Cabinet Key lock

• Industrial automation: Mounting PLCs, relays, and motor controllers in factory environments with moderate humidity and dust levels
• Power distribution systems: Low-voltage switchgear and meter cabinets for commercial buildings and residential complexes
• HVAC systems: Housing control panels for air conditioning units, ventilation systems, and heating equipment
• Transportation infrastructure: Railway signal control boxes, highway toll station electrical enclosures, and parking lot management systems
• Agricultural facilities: Irrigation control systems and livestock farm electrical distribution boxes (indoor or sheltered outdoor use)

• Sealing treatment: EPDM foam rubber strips at door seams (cross-sectional diameter ≥8mm, compression amount 30%), nylon waterproof joints for wire holes (IP68 rating, thread specifications M20-M63 optional), and 5° inclined drainage groove at bottom
• Heat dissipation design: Temperature-controlled system when internal temperature >40°C: Natural heat dissipation (ventilation hole area ≥0.05m²), forced dissipation (12V silent fan + dust filter, air volume ≥80m³/h), or heat pipe module for special environments
• Anti-corrosion treatment: Phosphating + electrostatic spraying (film thickness 60-80μm), stainless steel edge wrapping (304 material for box corners), or internal color galvanizing
