Features & Benefits:
- Fusing and switching requirements for the transformer assembly
- The design is of a shell type, using wound core technology, which provides a five legged core
- This design element reduces the circulating current and ferro-resonance within the tank, both of which can contribute to overheating
- This innovative feature is especially important where harmonic loading is a concern
- The coils are designed to meet the short circuit and specific voltage requirements of the customer
- The coil makes use of epoxy coated paper to increase its mechanical strength and cooling ducts are provided to ensure that adequate cooling is maintained within the coil even during overload periods
- The transformer is designed to meet customers’ specific climatic conditions and system requirements, including voltage connections and temperature rise
- It is important, when making an inquiry, to advise us of the average and the maximum ambient temperature for your transformer application
- The transformer enclosure section incorporates a sealed tank design using an air space to allow for the expansion and contraction of the oil
- A self-actuated pressure relief device is provided that will automatically activate at 10 psi, and which will reseal itself after excess pressure has
been released
- This device keeps outside air from coming into contact with the transformer oil, thus preventing the atmospheric moisture from being drawn into the oil
- Panel type radiators are incorporated as the size of the transformer increases, in order to provide sufficient cooling capacity
- Where required, an option for additional mechanical protection around the radiators without affecting the cooling requirements is available
