Thomas & Betts Product Will Withstand 100,000 Maintenance-Free Operations
MEMPHIS, Tenn., May 8, 2017 – The Joslyn Hi-Voltage® Transmaster® Switch from Thomas & Betts (T&B), a member of the ABB Group, is a heavy-duty vacuum switch that provides switching to electric furnaces in demanding environments, like steel mills, for up to 100,000 operations with no maintenance required.
Electrical furnace switches can operate more than 100 times a day. Using circuit breakers, which are not designed for constant operation, to control transformer magnetizing currents along with load and secondary currents can lead to increased maintenance. Containing no oil or gas for interruptions and insulation, the Joslyn Hi-Voltage Transmaster Switch is made to tolerate this level of heavy-duty operation without the frequent and costly maintenance required for circuit breakers.
The Joslyn Hi-Voltage Transmaster Switch operates uniformly under varied system conditions and is available for system voltages ranging from 15 to 69 kilovolts.
The Joslyn Hi-Voltage field-service team is available to perform switch maintenance and refurbishing.
"The constant switching that characterizes the control of the large amounts of power that electric furnaces consume wears on the service life of circuit breakers,” said Monica Perez-Therese, director, utility product marketing at T&B. “Our engineers worked closely with electric furnace manufacturers to develop the Joslyn Hi-Voltage Transmaster Switch in order to ensure that it would deliver the needed switching under demanding conditions, while no required maintenance.”
