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. Like the TLG, it uses a selector and reversing switch to regulate transformer secondary voltage under load without interrupting the circuit. The TLS is found in utility distribution transformers, and its collector ring finger contacts and main moving arm assembly are the components that see the most wear at normal maintenance intervals.

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

Lead time is confirmed at quote; discontinued or hard-to-find parts are reverse-engineered from a sample, a drawing, or a model number. Based in Palm Harbor, FL, Southern Switch & Contacts manufactures and ships replacement parts to utilities nationwide, and has served the industry since 1982.

Rebuild instead of replace

Worn but not scrap? Send us your used contacts. We recondition them to OEM dimension, or machine a new set from your sample, and return them tested and documented. Often cheaper and faster than buying new.
