HV Circuit Breakers

♦ Dead tank CB.

Dead Tank Circuit breakers are designed for reliable performance, maximized safety, and to operate within extreme environmental conditions including high elevation, very low and high temperatures (-60 °C to +60 °C ), seismic zones, polluted areas, and corrosive atmospheres.

♦ Rated voltage: up to 550 kV

♦ Rated continuous current: up to 5000 A

♦ Rated short-time withstand current: up to 63 kA

♦ Hybrid CB.

Hybrid compact switchgear consists of circuit breakers, disconnectors, and earthing switches located in a common gas tank.

Adding Current and voltage transformers gives us One solution.

♦ Rated voltage: up to 550 kV

♦ Rated continuous current: up to 5000 A

♦ Rated short-time withstand current: up to 63 kA

♦ Live tank CB.

Live Tank Circuit Breakers is the most commonly used and cheap type of C.B in the substation due to its design. It can be used in the energy field even in highly seismic, highly polluted, and low-temperature environments.

♦ Rated voltage: up to 800 kV

♦ Rated continuous current: up to 5500 A

♦ Rated short-time withstand current: up to 63 kA
