ABB, a power and automation technology group, has launched its next-generation LTA carbon dioxide (CO2) live tank high-voltage circuit breaker platform.

By replacing sulfur hexafluoride (SF6) gas with CO2 as the insulating and arc extinguishing medium, each new 72.5 kV LTA breaker has the potential to reduce CO2 emissions by 10 tons through the product lifecycle - which is 18% less than its predecessor, the company says.

The LTA circuit breaker technology is based on the same principles and components as its SF6-based predecessor and will be offered as a conventional circuit breaker and as a disconnecting circuit breaker (DCB). The DCB concept integrates the disconnecting function with the breaker, which ABB says eliminates the need for a separate disconnector and increases equipment availability and reliability with lower environment impact.
