Specialized Transformers and Inductors for Downhole Magnetics
As a custom transformer and inductor manufacturer for 40+ years, we have built downhole magnetics for a variety of downhole customers.
We are experts in designing downhole magnetics that operate in extreme environments. Our custom magnetics are designed to meet our specifications on temperature, size and shock vibration.
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.
Design Elements
The downhole industry, as with the aircraft industry, requires high reliability under extreme environments as a key element of the design. Custom Coils regularly delivers to customers who expect zero defects found. Materials used in downhole designs are very critical. Using the proper materials for the specific operating temperatures is imperative.
