Thomas & Betts, a member of the ABB Group, is a leader in providing products for the utility and steel mill industry. Our mission is to be the Brand of Choice for the end user of our products, and the Supplier of Choice for our distributor and industry customers. T&B offers the highly reliable Joslyn Hi-Voltage® VBT/VBU-T (Transmaster) Switches that have a proven record, with over 45 years of successful experience in electric furnace installations worldwide. These switches are available for system voltages from 15kV up to 230kV, and are modular in design, utilizing common parts and assemblies for varied voltage and current ratings. This design advantage allows easy maintenance and upgrade of switches when customer’s system parameters change. Key features designed specifically to reduce total cost-of-ownership include: Vacuum interruption and solid dielectric insulation, which eliminates the need for gas or oil; New digital Point On Wave (POW) closing, which reduces transformer energization transients; and Exclusive VacStat® vacuum interrupter monitoring technology, which allows the customer to monitor the vacuum status of the vacuum interrupter at all times.
