valves
Know what’s going on inside of your transformer with our transformer drain valves
Knowing the internal workings of your transformers is an important piece of the ongoing maintenance to keep them running properly. At THRADD our transformer drain valves are made from bronze and feature a sampler valve that allows you to test the internal oil. We feature valves in the 1” to 2” standard. Our valves allow for the drainage of oil from transformers as well as the addition of new oil. We work with our customers to provide valves that are specific and specialized to their exact needs. One of the things that sets THRADD apart is that we are a smaller company, and we’re able to respond quickly to our customers’ needs. We keep standard drain valve/sampler valve sizes on the shelf and are often able to ship the same day. Contact us today to find out how our expertise can benefit you.

Internal Transformer Connectors
Internal transformer connectors and stud connectors that are customized to your specifications.
THRADD prides itself on manufacturing quality internal transformer stud connectors for the power distribution industry. We set ourselves apart by machining an internal transformer connector that is pure cast copper, manufactured precisely to your specifications. That pure cast copper gives our customers continuity from the coil of the transformer all the way through the pure copper bushing. Our focus on pure cast copper connectors are machined to a smooth finish on both sides, allowing for maximum connectivity, leading to better transformer efficiency.
We are experts in adapting to your needs quickly by making it a point to purchase locally sourced materials. This also gives us a higher level of control over the quality of the materials that we use. Contact us to produce a superior product for your substation power distribution transformers today.
External Transformer Connectors
External Transformer Connectors, Bronze Stud Connectors for the Transformer Industry
our bronze external stud connectors are tin plated for maximum protection against the oxidation and corrosion that would normally occur if left to the elements. Our external transformer connectors can be produced to your specs from a range of 1 1/8” to 4”. A smooth, machined finish on both sides of the transformer connecting pad allows for maximum connectivity.
We work closely with local suppliers of all our materials to maintain our commitment to machining the highest quality product possible. Contact us to produce a superior product for your substation power distribution transformers today.

Envirotemp FR3 Fluid
The natural ester fluid that beats the alternatives
Derived from 100% renewable vegetable oils, biobased FR3 fluid is superior to mineral oil and other natural ester fluids for use in distribution and power generation transformers of all voltage classes (both new and retrofilled); HV testing validates use of FR3 fluid though 765kV. FR3 fluid is also suited for other fluid-filled distribution and power equipment, such as voltage regulators, circuit breakers (switchgear), rectifiers, phase-shifters, and HVDC transformers.
Its unique properties provide advantages that mineral oil cannot match, and its effectiveness has been proven for decades in millions of transformers across the globe. In particular, with FR3 fluid you can expect:
