Transformer Flexibility Reduces Overall Operating Costs Designed To Meet Your Specific Application:
- Moloney Electric's transformers incorporate wound core technology which features an advanced five legged design
- This design element reduces the circulating current and ferro-resonance within the tank, both of which can contribute to overheating
- This feature is especially important where harmonic loading is a concern
- All our coils can be designed to provide the special taps needed for various voltage requirements on Electrical Submersible Pump (ESP) applications
- This feature eliminates the need to change transformers, thus reducing the need for redundancy in transformers and also the cost of removing and reinstalling transformers
- The coil construction provides a high mechanical strength assembly, which delivers additional reliability for units in the field
- This rugged construction is critical for remote applications and all other applications where enhanced reliability is of particular concern
- Units designed for variable speed drives include special ducting, and conductors, and are designed to allow for additional heating which occurs due to harmonics and loading
- Details on the harmonic content should be provided at the time of asking for a quotation
- Designs incorporate copper windings as a standard
- Aluminum conductor can be supplied as an option on the LV section of the coil in certain applications
- All the coils incorporate diamond spotted; epoxy coated insulating paper for additional mechanical strength. All the insulating paper is thermally upgraded, providing for normal long life of the active parts and for an extended transformer life
- The specialized tap ranges that are available eliminate the need to change transformers as the voltage requirements change
- The taps are rated full capacity at all tap positions, thus providing the maximum rating required
- Taps are available in up to 25 different positions
- Typical range is shown on the nameplate drawing (see typical nameplate drawing on inside right page)
