Exceeding Customer Expectations — ABB Live Tank Circuit Breakers
ABB has over a century of experience in developing, testing and manufacturing high voltage circuit breakers. Through the years, our circuit breakers have acquired a reputation for high reliability and long life in all climates and in all parts of the world. ABB is currentlyintroducing the future technology for high voltage circuit breakers. Our design work with constant improvements and simplification of our products have resulted in; 550 kV circuit breakers without grading capacitors; the Motor Drive with a servo motor system that accurately controls and monitors the contact operation and the LTB D circuit breakers with FSA1 that provide fast and simple installation at site.Our development program is strongly focused on providing added value for our customers. Our apparatus are manufactured in a workshop where we continuously are working with improvements regarding quality, work environment, environment and safety.

Technicalspecifications - General
Standard/Customer specification There are international and national standards, as well as customer specifications. ABB High Voltage Products can meet most requirements, as long as we are aware of them. When in doubt, please enclose a copy of your specifications with the inquiry. Tests Type tests (design tests) and routine tests (production tests) are required by standards. - Typetests Type tests are performed only once on one representative test object in accordance with applicable standards and are not repeated without extra charge. The purpose of the type tests is to verify the ratings of the design. - Routine tests Routine tests are performed on each circuit breaker before delivery in accordance with applicable standards. The purpose of the routine tests is to verify...
