Implementation
With extensive experience in High Voltage repairs, our team at Houghton International can often identify any problems or suggest improvement to coil specifications to improve lifespan or efficiency. During the manufacturing of the coils Grupomoller visited Houghton International to view our facilities and witness testing.
Overhaul
HiFlex Coils have a hot pressed resin rich cell, corona protection and stress grading tape applied and flexible outhangs for easier installation. This makes them ideal for larger or more complex rewinds as they do not require baking, varnishing or impregnating after the rewind. Coils are fully tested at the point of manufacture guaranteeing dielectric integrity.
Outcome
During the testing, all coils showed excellent results, providing assurance to Grupomoller of the high quality design of the coils. The coils were then vacuum sealed and packaged inside a moisture proof crate for transport to Mexico. Additional winding materials, including bespoke winding forks, copper, mika and final tapes were supplied with the coils.
We have enjoyed working with Houghton International, who supplied 72+2 HiFLEX coils for use in the rewind of a 4 pole generator. The coils produced fantastic test results, and the testing facilities at Houghton International meant we could be confident in delivering a high quality rewind for our customer.
Not only this, but our winders were also very pleased with the fit and flexibility of the coils, helping to make the winding process quicker and more efficient. Houghton International’s engineering expertise was an asset during this rewind, from initial assistance on coil specification through to state of the art testing. We would not hesitate to work with them again.
