Pressurizing Plants

Commonly referred to as pumping plants or pump houses, pressurizing plants are critical to the performance of a transmission feeder as HPFF cables require pressurization with dielectric fluid for reliable, everyday operation.
Walker’s plants are designed for ease of use and reliability with a premium placed on making our equipment operator friendly.

Circulating & Cooling Plants

In addition to pressurizing the fluid, a feeder can have a circulating or cooling plant to help augment cable ratings. Walker’s circulating plants move dielectric fluid through a feeder to remove hot spots which in turn increases capacities.

Walker’s plants can be upgraded to include forced air cooling and refrigeration which are popular options to increase HPFF cable ratings.
