Specialized Transformers and Inductors for Downhole Magnetics

Down Hole Magnetics

Being an industry-leading custom transformer and inductor manufacturer Custom Coils has built Downhole magnetics that fulfill our client needs. Over 50+ years of industry experience, we specialize in the design and manufacturing of downhole magnetics that can withstand extreme temperatures. Our transformers and inductors for downhole industry are designed to meet diverse specifications in shock vibration, size, and temperature.

Today, most of our downhole designs are for 200C and 220C although we have some that operate at 240C temperatures as well. As the downhole market continues to drill deeper, the operating temperatures have continued to increase.
