Characteristics of the Distribution Box Enclosure

The materials are diverse and suitable for different scenarios.

Metal types: galvanized steel, stainless steel (304/316), and aluminum alloy are the main ones; they have high strength, good heat dissipation, and impact resistance. Stainless steel is more resistant to coastal / high-humidity corrosion; they are suitable for outdoor and industrial heavy-load environments;

Plastic types: ABS, polycarbonate (PC); they are lightweight, have strong insulation, and low cost. UV-stable formula can be used outdoors; they are suitable for civilian and indoor lightweight scenarios;

Composite materials: They combine the rigidity of metals and the anti-corrosion / insulation properties of plastics, and are mostly used in special working conditions.

High-level protection design

IP protection: Commonly used in indoor environments is IP30/40, while for outdoor industrial use, it is mostly IP65/IP66 (dust-proof + water spray-proof), and some even reach IP67/IP68; Sealing is achieved through rubber sealing gaskets, rain shelters, and compression locks;

Environmental tolerance: Anti-UV coating, resistance to high and low temperatures (-40℃ to +85℃ is common), salt fog resistance, chemical corrosion resistance;

Explosion-proof / Flame-retardant: Special models meet IEC/UL explosion-proof standards, and the enclosure material is flame-retardant, reducing the risk of arc ignition.

Structure and Installation Flexibility

Modular: Expandable internal rails, terminal blocks, and compartmentalized design, facilitating capacity expansion and separation of wiring;

Universal Interface: Pre-set knock-down holes (KO), cable sealing sleeves, supporting wall-mounted, floor-standing, and embedded installations;

Easy Maintenance: Hinged doors, detachable panels, observation windows, some with locks to prevent unauthorized operation;

Heat Dissipation Design: Natural ventilation louvers, heat sinks, fans / heat exchangers available for high-power scenarios.

Electrical Safety and Compliance

Reliable Grounding: Metal enclosure has mandatory grounding terminals to prevent leakage;

Isolation of Insulation: Internal circuits of high and low voltage are separated in different compartments to prevent crosstalk and short circuits;

Comprehensive Certifications: Compliant with IEC 61439, UL 50, EN 62208, etc., ensuring global market access.

Apply differentiated features

Outdoor type: Thickened shell, rain cap, sun protection coating, resistant to typhoons / snow;

Indoor type: Simple and elegant design, focusing on space optimization and convenient wiring;

Industrial type: Resistant to vibration and shock, able to withstand dust and oil;

Data center / New energy type: High density, intelligent temperature control, remote monitoring interface.
