The double-break disconnector consists of one arm which is moved by the central insulator supporting it and closes the circuit on two fixed contacts, each of them placed on one of the two side insulators.
Two models are available:
The former (TBC) is characterized by an extremely simple design and it is rather cheap; the latter (STC) can provide very high performance levels, in particular under short-circuit conditions.
Rated voltage: 24 - 550 kV
Rated continuous current: up to 8000 A
Rated short-time withstand current: up to 75 kA (3 s)
