Vacuum Substation Circuit Breakers15.5 to 38 kV
VDH
VDH Series
Suitable for protection and control of distribution lines, networks and
transformers substations, switching of power transformers, motors and
capacitor banks, industrial main breaker requirements, etc.
Manufactured and tested to meet ANSI C37 and IEC 62271-100
standards.
Wide variety of voltage and current ratings to select the most economical
model for each application.
Metal enclosed, self-supporting and free standing construction, with
weatherproof design suitable for installation in an unprotected
environment.
All exterior parts fabricated from steel sheet with cataphoresis protection
as anticorrosive process which provides longlasting perfomance in
corrosive or contaminated environments.
Roof assembly particularly fabricated in aluminium to prevent eddy
currents around bushings.
Easy installation and accessibility, minimal maintenance and long
service life.
Vacuum Substation Circuit Breakers
GENERAL CHARACTERISTICS
Three pole vacuum interrupter stored energy operating mechanism
assembly, stationary mounted type.
Epoxy resin bushings including 4 hole flat pad stud connectors.
Epoxy insulated ring-core current transformers installed around the
bushings (up to two current transformers per bushing)
Low voltage compartment including control push-buttons, indicating
lamps, current transformers terminal blocks and auxiliary devices.
