State-of-the-Art Stock & Custom Dry Type High Voltage Transformer Manufacturer Offering Top Quality at Wholesale PricesDry Type High Voltage TransformersA dry type high voltage transformer simply means it is cooled by normal air ventilation and like all transformers, they are voltage changing and in some cases are used as isolation devices that is air cooled rather than liquid cooled. The transformer is designed with the case being ventilated to allow air to flow and cool the coils. Unlike oil filled high voltage transformer, which is cooled with oil or fire resistant liquid, dielectric dry type high voltage transformer units utilizes only environmentally safe, CSA and UL recognized high temperature insulation systems. Because they are fire-resistant they are well suited for installation in high-rise building, hospitals, underground tunnels, schools, steel factories, chemical plants and places where fire safety is a great concern. They require minimum maintenance and provide many years of reliable trouble free service. Important Factor When Choosing a Dry Type High Voltage TransformersTransformers are a key component in an electrical distribution system and serving critical needs. It's important to evaluate your decision from every angle before choosing a unit. These large dry type high voltage transformers are used in large industrial plant, data center, and in our electrical power distribution centers. TEMCo a leader in supplying dry type high voltage transformers can help in the process but below, we have listed some of the most important factors to consider when purchasing a dry type high voltage transformer. TEMCo has been in business for over 40 years and offers quality products at the lowest price.
Types of Dry Type High Voltage TransformersThere are several different construction methods used in manufacture dry type high voltage transformers. The different designs allow many different installations for different environments possible. The key difference in the design of these units is in the insulation of the windings. Below we have outlined some of these to give you a better knowledge of what type would fix your application. Open Wound - Dry Type High voltage TransformerThe open wound transformer is made by a dip-and-bake construction method. This is done by preheating the conductor oils and then, when heated, dipping them in varnish at an elevated temperature. The coils are then baked to cure the varnish. Vacuum Pressure Impregnation - Dry Type High Voltage TransformerThe vacuum pressure impregnation dry type high voltage transformers (VPI) appy the varnish coating in interchanging cycles of pressure and vacuum. The VPI process uses polyester resin and then the coils are cured in an oven. This process is better than the open wound because it uses pressure in addition to vacuum, and allows better penetration of the varnish in the transformer coil. The VPI units offer an increased resistance to corona. Vacuum Pressure Encapsulated - Dry Type High Voltage TransformersBecause they are encapsulated they are better in harsh and wet environments than the VPI counterparts. This process works by using several dip processes to encapsulate the coil assembly after which the coating is cured in the oven. There is also an encapsulated sealed transformer which is a open wound distribution transformer encased in an electrical-grade silica and epoxy, and totally enclosed in an heavy-duty style enclosure. Cast Coil - Dry Type High Voltage Transformers In a cast coil design, the coils are solidly cast in resin under a vacuum in a mold. The manufacturing process locks the windings in a strong epoxy resin with high dielectric strength, protecting the transformer from severe operating environments. Each of these different types of dry type high voltage transformers are suited for particular environments. It's important for you to understand where best to use each type. Remember that the cast coil transformer costs approximately 50% more than the VPE or VPI type unit. Therefore, your final selection can have an impact on the overall cost of the project. If you are looking for improved resistance to corona and increased mechanical strength of the windings are required, a VPI-type transformer would work better for your applications. TEMCo can help you selected the right type of transformers for your job. Our engineers and staff will take the time to understand your needs, and recommend the best solution for your particular applications. TEMCo believes their success has come by building long-term relationships with their customers, and providing the correct products and solutions are their #1 priority. With over 40 years of experience, let us show you why so many people trust TEMCo for all their dry type high voltage transformers. With their large inventory and the lowest price guaranteed their no reason to go anyplace else but to TEMCo.
