Outdoor Construction Site Circuit Control Box Power Distribution
Cabinets are widely used in various outdoor construction scenarios. In highway and railway construction, they power large machinery and
manage temporary facility power, adapting to complex terrains with
dustproof and waterproof designs. At building construction sites, they distribute electricity for
construction machinery and temporary areas, facilitating flexible
wiring. In oil and gas field operations, they provide power with
explosion-proof features and resist corrosion. For mining and quarry sites, they power heavy machinery, distribute
electricity for underground systems, and support high-current
output. In infrastructure projects like bridges and tunnels, they supply
power for equipment, manage temporary systems, and have high
protection ratings. In renewable energy construction, they power installation
equipment, manage temporary power, and integrate with energy
storage systems.
1. Clarify core requirements first
Power load: Determine the number of circuits and circuit breaker
specifications based on the total power of equipment (e.g., a 250kW
load requires a large-sized cabinet) to avoid underloading or
redundant waste.
2. Installation scenario: For outdoor/humid environments,
prioritize IP55 protection and stainless steel (SUS304); for dry indoor scenarios, galvanized steel plates can be chosen to
reduce costs.
Installation method: Wall-mounted models should be compact with a
height ≤500mm; floor-standing models need to consider maintenance space, with a
recommended depth ≥300mm.
3. Size customization: Precisely adapt to space
If installation space is limited (e.g., narrow equipment rooms),
adjust according to the principle of "prioritizing width reduction
while ensuring depth/height meets component layout" (e.g.,
300×200×400mm for low-load equipment).
If integrating multiple modules (e.g., surge protection +
multi-circuit sockets), a depth ≥250mm is recommended to reserve
space for wiring and heat dissipation.
4. Functional customization: Focus on core scenarios
Industrial construction sites: Prioritize customizing
explosion-proof switches and 63A industrial sockets to adapt to
heavy-duty equipment.
Temporary power distribution: Choose modular terminal blocks for
easy quick disassembly; redundant protection modules can be omitted to reduce costs.
Lightning-prone areas: Mandatorily add surge protection modules
(e.g., Class T2) to enhance safety.
