Hz series combination switch energy storage breaking device

What is a HECS short circuit?

The HECS-3/5S generator circuit-breaker, with short circuit ratings of up to 130 kA, satisfies the requirements of the largest pump storage power plants globally.

What is the HECPS-3/5S?

The HECPS-3/5S is an integrated solution that provides all functions required by pump storage power plants (PSPP) in one system and from a single manufacturer.

What components are included in a circuit breaker system?

The circuit breaker system for 80-130 kA includes a circuit-breaker, disconnector, capacitors, and control cubicle. Additional components, such as earthing switches, current and voltage transformers, and surge arresters, can also be included. The system is delivered fully assembled to minimize installation and commissioning time at the site.
