Dead tank circuit breaker for 245 kV

nnnn

Circuit breakers are key to ensuring network reliability and safety in your substation. With Alstom Grid,

nnnn

you are choosing a company that you can trust. We manufacture our circuit breakers based on

nnnn

state-of-the-art technology and in modern production facilities.

nnnn

Our SF6 dead tank circuit breakers

nnnn

accommodate customer needs with a

nnnn

high level of reliability on a daily basis,

nnnn

even under extreme conditions such as

nnnn

those in areas with high seismic activity,

nnnn

tropical climates, low temperatures and

nnnn

polluted conditions.

nnnn

Range

nnnn

The DTl-245 series is designed to meet

nnnn

different customer requirements:

nnnn

■ for a rated short-circuit breaking current

nnnn

of40 kA - the DT1-245P Fl breaker with

nnnn

spring mechanism

nnnn

■ for a rated short-circuit breaking current

nnnn

of50 kA or 63 kA - the DTl-245 F3/H1

nnnn

with spring or hydraulic mechanism.

nnnn

Both circuit breaker types are available for single pole operation (IPO) or for three-pole gang operation. The standard temperature application for

nnnn

low temperature areas is -30°C without any heating systems. Utilising either tank heaters or a mixed gas design, the DTl-245 dead tank circuit

nnnn

breaker series can be installed in regions with temperatures as low as -60°C.

nnnn

Testing

nnnn

Our circuit breakers meet the requirements of national and international standards. This has been confirmed by comprehensive type-tests based on

nnnn

the latest IEC and ANSI standards.

nnnn

Certified quality

nnnn

We design, manufacture, test and deliver our circuit breakers in accordance with the latest

nnnn

ANSI, IEEE and IEC standards, maintaining a quality assurance system according to ISO 9001

nnnn

and ISO 14001.

nnnn

Our advanced DT Series of thermal-assisted interrupters are characterised by leak-resistant,

nnnn

cast aluminium enclosures and durable low-energy, spring-operated mechanisms. More than

nnnn

80,000 circuit breakers with thermal-assisted interrupters and spring-operated mechanisms are

nnnn

in service worldwide.

nnnn
