Metal Shell Weatherproof Power Distribution Equipment 480V Temporary Power Distribution Box

Key attributes

Shell Material and Structure

• Metal Shell: The distribution equipment is housed in a metal shell, typically made of high - quality stainless steel or aluminum alloy. Stainless steel offers excellent corrosion resistance, making it suitable for harsh environments such as chemical plants, coastal areas, or industrial sites with high humidity and corrosive substances. Aluminum alloy, on the other hand, is lightweight and has good thermal conductivity, which helps in dissipating heat generated by the internal components.
• Robust Construction: The shell is designed with a sturdy structure to withstand mechanical impacts, vibrations, and external forces. It is usually fabricated with precision - welded joints and reinforced corners to ensure long - term durability.

Weatherproof Capability

• High - level Ingress Protection (IP) Rating: It is equipped with a high IP rating, commonly IP65 or higher. The “6” in the IP rating indicates that the distribution box is completely dust - tight, preventing any dust particles from entering the enclosure. This is crucial for protecting the internal electrical components from dust - related damage, such as short - circuits and overheating. The “5” or higher for water protection means that the box can withstand low - pressure water jets from any direction without allowing water to penetrate inside, making it suitable for outdoor use in all weather conditions, including heavy rain, snow, and wind.
• Sealing Gaskets: Special sealing gaskets are used around the doors, covers, and cable entry points of the distribution box. These gaskets are made of materials such as silicone rubber, which have excellent weather resistance and can maintain their elasticity over a wide temperature range. They create a tight seal that prevents the ingress of moisture, dust, and other contaminants.

Explosion - proof Design

• Explosion - proof Certification: The distribution equipment complies with relevant explosion - proof standards, such as ATEX (for European markets) or IECEx (for international use). These certifications ensure that the box is designed and tested to prevent the ignition of explosive gas or dust mixtures in potentially hazardous environments.
• Flameproof Enclosure (Ex d) or Increased Safety (Ex e):
  • Ex d: In the case of a flameproof enclosure, the box is constructed to withstand an internal explosion of an explosive gas mixture. The enclosure is designed with precise flame paths that cool the hot gases produced during an internal explosion, ensuring that the gases exiting the enclosure are below the ignition temperature of the external explosive atmosphere.
  • Ex e: For increased safety protection, the design focuses on minimizing the risk of electrical equipment becoming an ignition source under normal operating conditions. This involves using high - quality insulation materials, proper wiring techniques, and reliable connection methods to prevent overheating, arcing, and short - circuits.

Power Distribution Capacity

• 6 - 10 Power Distribution: The distribution box is capable of handling 6 - 10 different power circuits. It can be used to distribute electrical power from a single source to multiple loads, such as motors, lighting systems, control panels, and other electrical equipment. The internal layout of the box is designed to accommodate various types of circuit breakers, contactors, relays, and terminal blocks to ensure efficient and reliable power distribution.
• Customizable Circuit Configuration: The power distribution configuration can be customized according to the specific requirements of the application. Customers can choose the number and rating of the circuit breakers, the type of wiring connections, and the layout of the internal components to meet the needs of different electrical systems.
