Winding Wednesday

Our ALAMO Winding shop team is installing the barrier layer on this 3 phase coil. Measure twice, cut once to ensure precision and quality.

The barrier layer, composed of Thermally Upgraded Kraft Paper, is placed between High and Low Voltage windings to isolate them from each other.

The barrier layer often contains cooling ducts to allow flow of the insulating fluid to help draw heat from the windings and cool the transformer.

ALAMO is ready to help, so give us a call today!

Winding Shop Wednesday

The electrical core is currently being wrapped snugly in place on this newly wound 5 legged core and coil for a three phase substation transformer. It has been carefully rewound one coil at a time to its original specs.

Once the core has been wrapped, it will then be hooked up and head back to the ALAMO dry out oven before being tanked and filled under a hot oil circulation process.

Transformer Tuesday

This Customer owned single-phase polemount is starting the process of reconditioning. Our ALAMO team is currently removing this core and coil from its tank which will then be inspected and then moved to the drying oven to eliminate any moisture the core and coil and insulation may have taken on over its years in service.

While the core and coil are in dryout oven, the tank will head another way to be cleaned, sanded and painted before the core and coil is retanked.

After retanking and the replacement of new gaskets, the polemount will be vacuum filled to customer's specification with insulating fluid of choice before sealing, undergoing a pressure test, final testing and final QC.
