An enclosure is a cabinet that houses electronic equipment. It protects the contents from environmental conditions and users from electrical shock. Enclosures are made of different materials such as steel, fiberglass, metal, and polycarbonates. Fiberglass enclosures are made of silicate fiber that is primarily made from glass. They are used in thermal insulation applications such as roofing, tent poles, automobile bodies, and electrical enclosures.
Types of Fiberglass used in Enclosures
Fiberglass enclosures are molded under high heat and pressure to form stable material that can withstand chemicals and harsh environments. Fiberglass is grouped into different types according to the materials used. Here are the major types:
- A-glass: This is alkaline glass, and it is highly resistant to chemicals.
- C-glass: It is chemical glass and equally high resistant to chemicals.
- E-glass: This is electrical glass and is an excellent electrical insulator.
- AE-glass: AE glass consists of both alkali resistance and electrical insulation properties.
- S-glass: This is structural glass and comes with the best mechanical components and properties.
What is the Best Enclosure?
Fiberglass electric enclosures have various sizes and designs to serve different purposes. There are many things you need to consider when choosing one. The following key factors should guide you;
1. Size
This is the main thing you should look at when buying an enclosure. Ensure the height, depth and width match your needs. Ensure it can fit at your desired location, and you will still be able to open the door for maintenance. The number of components you need to put in the closure and the spacing between them should guide you on an appropriate size.
2. Thermal Issues
You will need to analyze the environment where your enclosure will be situated. Excess cold or heat can affect its performance or destroy some electrical parts. You should, therefore, look at the type of material used for the enclosure. Be sure that it can insulate and dissipate heat well. You may need additional heaters and air conditioning to regulate temperature.
3. Weight
You may need to mount your fiberglass enclosures in some cases to protect your items. The equipment’s weight will determine how easy or complicated the task will be for you. Go for something that suits its projected work for an easy installation process.
4. Modifications
Different fiberglass electric enclosures come with different features and modifications. Sometimes you may need to add a few changes for it to work perfectly. These could include adding cutouts and holes for mounting or access. Choose one that has many features and needs little to no modifications.
5. Environment
All enclosures have NEMA ratings that specify the kind of environment you can use them in. It could be indoor or outdoor use, together with conditions such as water and dust. Check the NEMA ratings and guidelines to know what the enclosure offers.
Benefits of Fiberglass Electrical Enclosures
There are many reasons why most people prefer fiberglass enclosures to polycarbonate enclosures. They work well in environments exposed to direct sunlight or organic solvents. They are generally stronger than other materials, highly resistant to rust, and inflammable.
Fiberglass has unlimited possibilities when it comes to molding. Manufacturers can make a comprehensive design of beautiful products that are functional and durable. They can easily make them out of different shapes. Below are more reasons why fiberglass electric enclosures are most preferred.
I. Budget-friendly
Fiberglass is a good option for businesses and individuals with a lower budget for enclosures. They are typically cheap, especially when compared to steel and metal enclosures. Their lightweight also makes it affordable to ship. Furthermore, fiberglass has low maintenance costs, so you can comfortably have it for several years before replacement.
II. Moisture Resistance
It is the best enclosure for moisture-prone areas as it doesn’t absorb water. It is fixed with insulation on its sides that is regularly inspected in moisture environments. As long as it is still in good condition, it is dried, cleaned, and restored to its original appearance.
III. Versatility
Versatility is one of the top reasons why fiberglass enclosures are popularly used. They can be used in a wide variety of applications, unlike other enclosures. Besides electrical insulation, these cabinets can protect items from chlorination and organic solvents, among others.
IV. Easy to Install
Enclosures made out of fiberglass come prefabricated, thus, less time for installation. This saves any business time, which is of the essence for their daily activities. It is the quickest way to protect equipment than any other enclosures when the need arises.
V. Environment-friendly
Fiberglass is made out of purely recycled material that is friendly to the planet. Insulation products like loose-fill, roll, and batt are made out of about 80% recycled glass. Ingredients used in the manufacture of this enclosure include silica sand which is less harmful to the environment.
VI. Sound Absorption
Most electronics typically produce sounds that may distract workers on business premises. If you’d love to avoid this, then enclosures made out of fiberglass are your best bet. Its acoustics can absorb sound waves produced by machinery, keeping the sound levels low.
Conclusion
You can conveniently protect your equipment from different conditions with a wide variety of fiberglass equipment enclosures. They have powerful electrical properties and can stand extreme temperatures of up to -40 degrees on the lowest and 142 C on the highest. It is a cheaper option to install or replace when you are on a limited budget.
