GE pioneered experimental vacuum interrupters in the 1920s. Refined it and introduced the world's first 15kV Vacuum circuit breaker in the 1960s. To date, this interrupter design has been the world leader in vacuum technology and has accumulated over 45 years of reliable field service.
Manufactured, assembled and tested all in the same sophisticated facility, SecoVac is the product of state of the art manufacturing processes assured by ISO 9001:2008 and ISO 14001 certification. Precision tooled parts, computer aided d e s i g n a n d a d v a n c e d p ro d u c t i o n techniques, as well as the protection of the 'E Coat' (cathodic electrocoating) paint process have resulted in a standard of excellence unmatched in the industry.
SecoGear is designed, assembled and tested to meet or exceed applicable IEC, GB and DL standards. It is suitable for applications in all major industries including T&D, Oil & Gas, Automotive, Processing plants, Iron and Steel mills, Mining, Commercial buildings, etc. It provides protection for all types of applications: coble, overhead lines, motors, capacitors, transformers, busbar sections, etc.
Selecting low environmental impact technologies has become increasingly important to engineers tasked with choosing equipment for an application. W i th commitment to env i ronment protection, the solid insulation of epoxy resin is used for SecoVac series MV embedded pole vacuum circuit breaker instead of SF6 gas.

total mechanical life tests to verify that
the quality is identical to that of the

The IP protection degree is the resistance

of solid objects and liquids. This degree
of resistance is indicated by the prefix IP

Environment
Increasing global legislation concerning the use of green -
house gases such as SF6 gas and their related disposal costs,
makes vacuum technology with its reliability, low maintenance,
and low environmental impact the choice for now and the
future.
As the world strives to reduce the amount of SF6 gas used
in all applications there is a responsibility on the users of
electrical switchgear to find, where appropriate, alternatives to
SF6 gas as an insulation and switching medium. Air and solid
insulation switchgear systems incorporating vacuum switching
technologies are a reliable, safe and economic alternative for
use in electrical systems below 36kV and therefore should be
used instead of SF6 gas insulated systems.
Modern medium voltage switchgear employing vacuum
technology together with air and epoxy resin insulation
provides:
No special requirements for the end-of-life disposal of the
switchgear
No use of SF6-gas for switching and insulation
No risk of damaging leaks of SF6 gas or of toxic byproducts
Energy-efficient production and assembly, with
environmentally friendly energy sources
enables low energy loss during operation
Only re-usable and/or recyclable materials used

accordance with the rules and procedures

SecoGear are critical to determining
how environmentally friendly the
its materials to ensure that they have
the lowest possible impact on the
environment. It is essential that they are
equally safe for people not just during use,
but at the end of service life too. Within
SecoGear and the SecoVac vacuum circuit
breaker, a combination of solid (cast-resin)
and air is used as insulation. The cast-
resin technology, in combination with
electrical field calculations, provides a very
compact, environmentally friendly design
Because the switching medium - vacuum
– is used, SecoGear can be completely
recycled at the end of its life without
any issues relating to safety procedures,
special handling or safe disposal.

interlocking mechanisms required for safe and
reliable operation of the vacuum circuit breaker.
Manual operation buttons allow for full operation
of the vacuum circuit breaker from the front of the
switchgear with the door fully closed. The circuit breaker is
mechanically interlocked with the compartment door so that
the door cannot be opened until the circuit breaker is switched
off and racked out into the Test position.

In order to obtain an optimum installation sequence and ensure
high quality standards, site installation of the switchgear should
only be carried out by specially trained personnel, or supervised
and monitored by qualified personnel, or by personnel supervised
and monitored by responsible persons.
On commencement of installation on site, the switch-room
must be fundamentally finished, provided with lighting and the
electricity supply, lockable, dry and with facilities for ventilation,
It is also required that the basic frame and indoor ground
of substation should be checked and accepted before the
construction, It must be ensure that the ceiling height is sufficient
for the opening travel of the pressure relief plates and clearance
