High quality safety vcb ZW32-12D/630-20 series pillar type outdoor
high-voltage
12kv vacuum circuit breaker
Product Introduction
ZW32-12 outdoor high voltage AC vacuum circuit breaker is a
three-phase AC outdoor high
voltage power distribution device with the rated voltage of 12kV
and the rated frequency of 50Hz,
used to protect and control load current, over-current and
short-circuit current in breaking and
closing system in substations or power distribution system of
industrial and mining enterprises
below the altitude of 1000m, as well as in rural power grid and
other places that need frequent
operation.
Product Features
1. The breaker is designed in an integrated structure that the
primary electrical parts of the three-phase
post is connect to the operating box into a whole. The three-phase
post structure makes the opening
stable and reliable with no burning or explosion risks and
requiring no maintenance. Besides, it is small,
light and has long working life.
2.The vacuum arc extinguishing chamber is fully enclosed and
sealed. It is moisture-proof and anti
condensation, especially suitable for humid areas with high
temperature.
3. The three-phase post and the current transformer are cast by
epoxy resin or silicon rubber, which has
the advantages of high insulation, good resistance to low through
high temperature, ultraviolet and aging.
4. The operating system can be small-sized spring mechanism or
permanent magnet mechanism.
Transmission is performed directly by force with less parts needed,
lower energy consumed on opening
and closing and higher reliability. The operating mechanism is
arranged in the sealed box, solving the
problems of corrosion and improving the reliability of the
mechanism.

Product characteristics
1. The performance of the product is stable and reliable as the
product adopts three-pillar type
structure, and the vacuum arc-extinguishing chamber connects with
the operating mechanism
through insulation pulling rod;
2. Arc-extinguishing chamber, main conducting loop and insulation
support are casted into an
organic whole by epoxy resin with APG technology, and encapsulated
with silicon rubber, it is
provided with good anti-condensation performance and mechanical
strength.
3. The switch adopts a high performance spring operating mechanism
with the advantages of
simple structure and long mechanical life, and with the functions
of manual/electric energy storage
and opening/closing operation.
4. An integrated isolating switch is optional for the product.
5. The product has the advantages of small size, novel appearance,
light weight and easy installation.
6. The switch can be equipped with control terminal interface to
apply to automation distributiong
networks and the unattended substations.
