Vacuum Contactors
CO2 Laser Therapy Apparatus
He-Ne Laser Therapy Apparatus
Aircraft Meal Carts
Guard Tour System
The
series JCZ-6 of
high-voltage vacuum
contactor are suitable
for the distribution
system of metallurgy,
mine, petro-chemistry
and building, to control
the equipments used
eletricity such as
high-voltage motor of
6kV or under 6kV,
transformer and capacitive
loading etc. Especially
suitable for frequent
operation domain. Because
of its small volume, light
weight and packaged
design of upper and lower
arrangement, prevalented
in the world. It is convenient
to use and main tain, and
is easy to form the complete
equipment of F-C loop.
