What is Electrical Enclosure?
What is the definition of electrical enclosures?
Electrical enclosures are cabinets used to install switches, knobs, and display for electrical or electronic equipment .It also can prevent electric shock to the user of the equipment and protect the inside electrical components from the environment. The shell is the only part of the device that the user can see. It may be designed not only for its utilitarian requirements, but also for pleasing the eyes. Regulations may dictate the characteristics and performance of electrical equipment enclosures in hazardous areas, such as petrochemical plants or coal mines. Electronic packaging may place many requirements on the enclosure to achieve heat dissipation, radio frequency interference and electrostatic discharge protection, as well as functional, aesthetic, and commercial restrictions.
What material will the electrical box be made of?
Electrical enclosures are usually made of rigid plastic or metal (steel, stainless steel, or aluminum).
Steel electrical boxes /Carbon Steel Enclosures
The steel cabinet can be painted or galvanized. For the properties of carbon steel and stainless steel,they will be selected to make for electrical enclosure boxes for high durability and corrosion resistance.
When producing steel electrical enclosures,carbon steel can be hot or cold rolled. Hot rolled carbon steel is used for stamping and moderate forming applications. Cold rolled sheet is produced from low carbon steel and then cold reduced to a certain thickness and can meet ASTM A3666 and ASTM A611 requirements.
In general there are three typical configurations for the fabrication of carbon steel enclosures: hot rolled, cold rolled and galvanized.
Enclosures fabricated from either types of mild steel are acceptable for many indoor and outdoor environments, but they typically will not receive a corrosion resistance rating. However, the performance of these materials is greatly improved by applying a powder-coated paint finish.
There are a wide range of installation options for carbon steel enclosures:
Free standing steel enclosures
Pad mount steel enclosures (open bottom with an internal flange)
Wall mount steel enclosures
Pole mount steel enclosures
Walk-in steel enclosures (with or without floors)
What about stainless steel electrical enclosures?
Stainless steel enclosures will be an excellent choice to use when moisture resistant and chemical resistant are required.Thanks to the property of high durability and corrosion resistance,stainless steel electrical box are suited for medical, pharma, and food industry applications.Regarding the stainless steel enclosure box,we are all familiar with stainless steel weatherproof box,stainless steel wall box,stainless steel terminal box,stainless steel push button enclosure,stainless steel push button enclosure,stainless steel push button enclosure.For any kind of above electrical enclosures,you may find the satisfied one from a professional enclosure manufacturer Zhongfeiya Tech.
Aluminum electrical box
Aluminum is chosen to make aluminum electrical box because of its light weight, relative strength, low cost, and corrosion resistance.So aluminum electrical box performs well in harsh environments. Aluminum electrical enclosures are sturdy, capable of withstanding high impact with a high malleable strength. We can also use a aluminum electrical enclosure as a shield against electromagnetic interference.
Polycarbonate electrical enclosure
For polycarbonate electrical enclosure (called plastic enclosure box), ABS is used for indoor applications in non-harsh environments.We usually call it plastic surface mount electrical box.It’s easy to find plastic surface mount electrical box,small plastic enclosure, and abs plastic enclosure for electronics from Zhongfeiya Tech.
Polycarbonate, glass reinforced and fiberglass boxes are used where stronger cabinets are needed, and there may be an additional gasket to remove dust and moisture.
The polycarbonate enclosures from Zhongfeiya Tech can house electrical and electronic controls and instruments in harsh indoor and outdoor environments, the polycarbonate enclosures help protect against corrosion, windblown dust and rain, sleet, snow, splashing or hose directed water, UV and flames. But those non-metallic enclosures may require additional installation steps to ensure that the metal conduit system is properly connected.
The metal cabinet can meet the electrical conductivity requirements for safe electrical connection and shielding electromagnetic interference of enclosed equipment.
Fiberglass electrical enclosure/SMC electrical enclosure
Fiberglass electrical enclosure is also called SMC electrical enclosure.Fiberglass enclosures resist chemicals in corrosive applications. The material can be used over all indoor and outdoor temperature ranges. Fiberglass can be chosen and installed in wet environments.
