In the power distribution industry, the extension of internal component life in arcing equipment is critical to system reliability. Maintenance intervals of substation equipment are key to reducing operating and maintenance costs. The formation of varnish, or filming, and sludge lead to coking of energized internal components, forcing unplanned outages. Filtration of insulating oils is imperative for the prevention of unexpected equipment failure. Filmax Advanced Filtration Systems is an established manufacturer of filtration equipment supplying more than 5000 units to more than 100 power distribution companies in the United States and Canada. Its utility filtration equipment has been in continuous operation for up to 15 years. Filmax’s AFS equipment can eliminate varnish and sludge in the most critical substation distribution equipment. The company offers a full product line of low flow dedicated equipment as well as high flow mobile and stationary equipment.
