The EconiQ 420PM63-HA is the first eco-efficient Dead Tank Circuit Breaker (DTB) at transmission voltage level. It combines a low carbon footprint, superior reliability and low life cycle costs.
EconiQ is Hitachi Energy’s eco-efficient portfolio with products, services, and solutions proven to deliver exceptional environmental performance.
Throughout its complete life cycle, the EconiQ 420PM63-HA Dead Tank Circuit Breaker significantly reduces CO2 equivalent (CO2eq) emissions compared to the existing SF6 solutions.
This product offers easy operation at high-performance ratings by using well-established gas circuit-breaker technology, which has been utilized for decades in transmission systems globally.
The eco-efficient Dead Tank Circuit Breaker uses as a gas mixture of Carbon Dioxide (CO2), Oxygen (O2) and a specific fluoronitrile (C4-FN). The mixture essentially eliminates the CO2eq emissions of the insulating medium.
The 38-72.5 kV Dead Tank Circuit Breakers (DTB) are designed to excel in a broad range of power applications. Utilizing technology pioneered by Hitachi Energy and used across the industry today, the Dead Tank Circuit Breaker line features slipover current transformers as well as independent pole capability and self-blast interrupters.
The 123-170 kV Dead Tank Circuit Breakers (DTB) features a small footprint and a single piece interrupter with factory-aligned contacts that reduce installation and maintenance costs.
The 550 kV Dead Tank Circuit Breakers (DTB) can be equipped with pre-insertion resistors and are tested for high transient recovery voltage (TRV) performance, high mechanical endurance and switching capabilities. Installation time is greatly reduced due to control wire bundling.
For shunt reactor protection, Hitachi Energy offers Dead Tank Circuit Breakers with applied, internal Metal Oxide Varistors (MOVs). This solution increases the reliability of the breaker by limiting damaging overvoltage’s.
