What does Relative Spacing and Customization in Electronic Enclosures Means?

Spacing in NEMA 4x, 6p enclosures

There are a lot of articles on the internet that talks about how the relative design concepts work that utilizes spatial relationships in identifying the key locations of some enclosure cutouts.

Some of the enclosure manufacturing company’s engineers work with these concepts most of the time. They are more than willing to give help to consumers or companies that need help with some design concepts. Most of the time a consumer will have a wide understanding of what they would be needing in terms of the specifically sized enclosure. A customer service representative can help the company or end user choose the proper enclosure that will be very suitable for the user or company’s needs. With this in mind, companies create a concept quote for different machining holes that are located in proper locations.

Once the customer is ready to place her order for the enclosure, the engineers can design or create a 3-dimensional drawing that will help in the programming of the CNC machines. One example of this is that when the end user or customers send in a drawing or calls the ballpark for some of the pricing modifications. Without the use of some of the specific dimensions, the companies can give pricing that is totally based on the space measured on top of the enclosure.

However, when the customer gives exact dimensions of the enclosure, it seems that the hole has the size of only 1/2” in diameter. Whilst the enclosure pricing can greatly vary by a minimum amount of pennies basing on the size, another approach should be taken to make the large portion of the enclosure removed. This factor can highly affect the form and structure of the enclosure while it is clamped into the CNC machine so that the companies can use a quote that utilizes a very effective method in this specific example.

This is one of the reasons why companies are asking for the dimensional drawing of the enclosures at the time the order was placed. While the companies can give an exact quote of the enclosure based on the estimated time frame on relative description, the companies would need to have a very precise measurement in order to remake the proper holes.

Majority of the companies can work on any format the companies provide for enclosure and they are always more than willing to help out the companies in customizing the electronics enclosure they are needing.

There are also different design for electrical enclosure depends on the rating of enclosures, NEMA 4x enclosure and NEMA 6P are an example. They give a different level of protection, so they will have a different design to give proper protection to your application.

The Effect of Emergence of Dry-Type Outdoor

Effect of Emergence of Dry-Type Outdoor

For decades now, the terminations of oil-filled have been the normal standard for high-voltage cables. However, being deviant from this former technology are being operated by some of the pre-molded dry-type outdoor terminations.

Last 2018, the 138kV are being pre-molded in areas where there is the existence of dry-type outdoor terminates. These are being installed across three different regions in the world for the first time ever: Ansonia, Philippines, Malaysia, Connecticut. Each of these countries is having an application of mechanical shrink installation technology to their new and existing grids.

In order to meet the increasing demand for some of the regional grid efficiency modernization. The 138kV termination brings about numerous benefits. One of which is the initial termination that being installed in some of the voltage levels that utilize the shrinkage of the installation method. The 138kV dry-type outdoor termination constitutes protection from harsh weather and the termination of this has brought great weather sheds that possibly lock out some of the environmental elements.

With this in mind, rubber construction greatly offers some great benefits. Having dry-type terminations are 20% to 30% lighter and this allows companies for easier installation. Once the system is fully tested and it has been pre-expanded within the factory, it allows the creation of straightforward installations happening in the field. And it has greatly reduced the potential of having field damage and some devastations installation errors. This no longer contains oils and these terminations brought about avoidance of field damage from having any potential leak that also requires maintenance. Because this can bring unexpected power outages.

This brings fewer parts that are needed to be installed and there are no more installation tools required. The weight has been greatly reduced, and this product should effectively and significantly decrease the risk of having field damage, installation time, and dependence on some of the jointers. This happens spontaneously while the improvement of the overall grid efficiency is happening. The flexibility and lightweight of the said equipment allow for the horizontal, vertical, and angled mounting positions. The installation of some of the oil-filled equipment usually requires machinery that is heavy in nature. This drives up some of the labor costs and it shows some limits in installation options due to the fact that the proximity to the energized overhead lines.

The installation of pre-molded dry type shows greater demand whereas the new grids are being currently developed while the level of electrification is now low. In some of the developing countries, it is easier and cost-effective option.

While there is a transition happening in the U.S. is slower, the installation in systems such as Ansonia should be the start of the beginning for the utilization of Americans and move toward the dry-type single-piece pre-molded outdoor termination. Together with the shrinkage mechanical installation method in improving grid efficiency.

There is once instance where a puppy playing for several us is so worn out that he was not even able to leave the couch. With this in mind, the owner was able to curl up with the puppy and make him relax without having the mind crazily roaming around the garden. While couching on the sofa, the owner was watching several commercials on TV. And it made her wonder, of all the commercials she just saw, how can customers decide on which products should they buy? Is it because of the benefits the commercial showed? How they can make sure that the product they are buying will deliver its promised benefits? Is there also a factor in what products their closest friends will recommend them? These are some of the questions the dog owner asked herself when watching those infomercials on television. 

This question also applies to the current dilemma of the companies that would like to have enclosures as a way to protect their equipment from certain elements. Designs and different classifications of sizes and colors, there is almost unlimited number of enclosures available in the market. The companies can call the manufacturing company to ask for the necessary information that they need in deciding which enclosure do they need for a certain operation task. There also customization needs a company might ask from the manufacturer. It is important to ask crucial information that will help them decide which enclosure is best suitable for them. 

With this in mind, there are two ways of making this selection easier for companies: 

Step 1: Determine the size needed for the enclosure 

To begin the decision-making process, the company should ask and determine the size of their equipment and components that will be housed inside the enclosure. Will they be needing a battery pack? If so, how many batteries does this battery pack should have? Aside from this what else does the enclosure should protect? Is it the LCDs, switches, lights? Some of the manufacturing companies offer enclosures that are easily customizable and can accommodate the needs of the companies. However, the customization of molded plastic enclosures requires a lot of time because it is time-consuming and most of the time more expensive. 

Step 2: Determine the protection needed for equipment inside

With the different needs for an electrical enclosure, the right type of enclosure to give the right protection level should be determined in making sure that the characteristics of the enclosure will solve the needs of the company. So how do you know, how to compare different type of enclosures? Yes, you need the standard that you can follow. There are 2 common standards for electrical enclosures, NEMA and IP. NEMA is commonly used in the USA, IP is usually used all around the world except in North America. The common rating is NEMA 4x enclosure or IP65 and IP66, which gives the protection to heavy rain and constructed for the outdoor environment. These enclosure are also considered as weatherproof enclosures. Of cause, there are other types that waterproof which can be submerged under the water, we will talk about that in the future article. Basing from the assembled project, the company should determine which equipment or component will be housed inside the enclosure. Also, the company should take note that they need to leave extra space inside the enclosure. Some enclosure companies make only external measurements. Once the company gives the right measurement for the enclosure that they need, they should include the thickness of the material of the enclosure in their measurement.
