About the Allis-Chalmers TLS

The Allis-Chalmers TLS is a reactor-type load tap changer sharing design lineage with the TLG but with a different contact geometry, hub assembly, and collector ring arrangement. It is found in utility distribution transformers across the Southeast and Midwest. Southern Switch refurbishes original TLS moving finger contacts and stationary contacts to OEM dimensional specifications, restoring contact face geometry and silver surface condition to return the tap changer to original switching performance.

Why replace worn LTC contacts

Worn or burned tap-changer contacts raise resistance, run hot, and can lead to tap-changer failure. Precision replacements restore reliable switching and extend the service life of the LTC.

Stock, lead time & reverse engineering

Common items are produced on short lead times; discontinued or hard-to-find parts are reverse-engineered from a sample, a drawing, or a model number. This part is supplied new or remanufactured. Based in Palm Harbor, FL, Southern Switch & Contacts manufactures and ships replacement parts to utilities nationwide, and has served the industry since 1982.
