Retrofit solutions for ALIND/ALSTOM HL make minimum
oil circuit breaker
The foremost advantage of retrofitting
a circuit breaker in switchgear is that
the required specifications are met
with the latest technology at only a
partial cost of replacing the equipment.
This becomes more evident when
the associated costs of civil works,
cabling and downtime are considered.
Retrofitting helps in saving up to 60
percent of the cost of new equipment.
Typically, retrofitting constitutes
replacement of vital equipment having
similar or advanced features, for life
extension, reduced maintenance and
improved functionality. This includes
upgradation and modernization of
basic equipment and allied parts. The
retrofitted switchgear offers far greater
system, reliability, long term safety and
long term availability of spares with
minimal investment and downtime.
ABB is a full system provider for
retrofit solutions, from the proposal
and design, through the manufacturing
and testing, up to the installation and Alind/Alstom HL breaker
commissioning.

Facts
These circuit breakers are widely present in the networks and
ABB can provide the relevant retrofitting solutions across the ABB VD4 vacuum retrofit of Alind/Alstom HL breaker
globe. This equipment has been in service for many decades
and retrofitting could significantly extend the operational life
of the switchgear. The use of well proven VD4 Vacuum circuit
breaker enhances the reliability of the switchgear. The retrofit
circuit breakers can be fitted with Surge Arresters or Potential For more information please contact Service department at:
Transformers on request. Many types of existing circuit
