JST Power Equipment is one of the largest manufacturers of Cast Resin Transformers in the world, able to design, test and build transformers to meet some of the most challenging applications in the market today. Our teams of engineers have been leading the industry for over 25 years in terms of technology advancements, quality and customer support.
When in harsh environments – such as outdoor installations, corrosive environments, off-shore applications, petrochemical facilities and the like – it is best to choose a Cast Resin Transformer for your needs. This type of construction is designed specifically to protect the coils from the devastating effects that salt, water, particulates, caustic substances and sun can have on a transformer. For longest life and improved system reliability, Cast Resin Transformers are designed to survive. Cast Resin Transformers are also designed to stand up better than oil filled transformers for harsh duty applications where rapid cycling or short, high current overloads are expected, such as in many industrial processes. This robustness leads to improved system reliability and lower maintenance costs though out the life cycle of the transformer.
We build Cast Resin Transformers for a wide array of applications, sizes and configurations. Currently we are able to build units up to 45MVA, 40.5kVA and 200 kV BIL. JST provides a wide array of options when it comes to enclosures to help you meet your system needs. JST enclosures are designed to meet all requirements of CSA and UL 50.
