Armature Electric, 13.2 Kv refiner motor

Armature ElectricManufacture and supply of 48+2 high voltage stator coils with a transposition twist for a 13.2Kv refiner duty motor delivered to British Columbia, Canada.

We manufactured and supplied all coils and auxiliary winding kit, utilising our HiFLEX fully cured and fully flexible insulation system which gives improved fit, easier install and reduces the risk of damage to the coils during installation.

As per our specification, the coils were manufactured to tight tolerances giving a consistent fit which helps to reduce PD levels. With higher voltage machines PD is a critical factor in the life expectancy of the motor. We understand that quality and fit of coils impacts PD readings and work to tight tolerances to give best results.

“Over the past couple of years we have been utilizing the Houghton HIFLEX High Voltage coil design. The feedback that I have received from our winding teams is rather positive. They are very impressed with the precision of the coil geometry and the overall high quality of the coil build and finish.

“The final PD testing of the last Large HV Motor, (a 14,000HP GE refiner duty motor), produced the best test results we have ever seen. This is a true testament to the high quality standards built into the HIFLEX coil design.

“The entire team at Houghton is a pleasure to deal with, they are very professional, extremely responsive, highly knowledgeable and always willing to take the time to work through any technical issues that arise.

“In our market, customers demand the highest quality product for their critical assets, we can honestly say that we can exceed their expectations both with the quality of product and delivery responsiveness.

“We will continue to promote the Houghton coil systems to our customers and we look forward to continuing our relationship with Houghton International.”
