nnnnDead tank circuit breaker for 245 kV
nnnnCircuit breakers are key to ensuring network reliability and safety in your substation. With Alstom Grid,
nnnnyou are choosing a company that you can trust. We manufacture our circuit breakers based on
nnnnstate-of-the-art technology and in modern production facilities.
nnnnOur SF6 dead tank circuit breakers
nnnnaccommodate customer needs with a
nnnnhigh level of reliability on a daily basis,
nnnneven under extreme conditions such as
nnnnthose in areas with high seismic activity,
nnnntropical climates, low temperatures and
nnnnpolluted conditions.
nnnnRange
nnnnThe DTl-245 series is designed to meet
nnnndifferent customer requirements:
nnnn■ for a rated short-circuit breaking current
nnnnof40 kA - the DT1-245P Fl breaker with
nnnnspring mechanism
nnnn■ for a rated short-circuit breaking current
nnnnof50 kA or 63 kA - the DTl-245 F3/H1
nnnnwith spring or hydraulic mechanism.
nnnnBoth circuit breaker types are available for single pole operation (IPO) or for three-pole gang operation. The standard temperature application for
nnnnlow temperature areas is -30°C without any heating systems. Utilising either tank heaters or a mixed gas design, the DTl-245 dead tank circuit
nnnnbreaker series can be installed in regions with temperatures as low as -60°C.
nnnnTesting
nnnnOur circuit breakers meet the requirements of national and international standards. This has been confirmed by comprehensive type-tests based on
nnnnthe latest IEC and ANSI standards.
nnnnCertified quality
nnnnWe design, manufacture, test and deliver our circuit breakers in accordance with the latest
nnnnANSI, IEEE and IEC standards, maintaining a quality assurance system according to ISO 9001
nnnnand ISO 14001.
nnnnOur advanced DT Series of thermal-assisted interrupters are characterised by leak-resistant,
nnnncast aluminium enclosures and durable low-energy, spring-operated mechanisms. More than
nnnn80,000 circuit breakers with thermal-assisted interrupters and spring-operated mechanisms are
nnnnin service worldwide.
