Feature Friday

This 10 mVA Substation transformer was just reconditioned at our ALAMO Houston shop. It is completed with galvanized rads helping the external cooling of this transformer.

It has also received a new coat of our ALAMO heavy industrial 2 part acrylic urethane coating. This helps protect our customers from the corrosive Gulf Coast weather conditions and helps their transformer last for years to come.

Transformer Thursday

ALAMO Installs painted galvanized radiators on a customer's 10 mVA sub. These galvanized radiators help with the external cooling of oil immersed substation transformers, as the radiators circulate the hot oil through the thin panels to dissipate the heat inside the transformer tank. The painted galvanized radiators provide superior rust and corrosion protection in harsh outdoor environments in plants, under cooling towers, and along the Gulf Coast, working to extend the life of your transformers for years.

Once testing is completed and the failure points are identified, the ALAMO Winding Team will make the necessary design changes and repairs before rewinding the coils.

ALAMO Fabricated a New Lid with an Elevated Manhole cover and SPRD. This Substation is designed to combat high-risk corrosive environments like the Texas Gulf Coast. The elevated manhole provides a safe and efficient way for inspection and maintenance activities.
