PRODUCT HISTORY
VacClad-W Switchgear with Type VCP-W Drawout Vacuum Power Circuit Breakers
Westinghouse VacClad-W world class
medium voltage metal-clad switchgear
with type VCP-W vacuum power circuit
breakers was introduced in 1986. VCP-W
breakers and switchgear were similar to
but not interchangeable with the original
Vac-Clad (VCP) product.
The VCP-W design includes a consolidation
of improvements in product design

and performance that enables the introduction
of IEC and 27 kV breaker ratings.
However, VCP-W still includes many of the
proven product features of VCP switchgear
design, including two-high breaker stacking,
V-flex breaker current transfer and fluidized
epoxy insulation on the switchgear
phase buses. VCP-W breakers withdraw
onto removable switchgear rail assemblies
for ease of inspection. VCP-W breakers and
Cutler-Hammer offers an extensive
amount of products to support VacClad-W
switchgear.
Complete New VacClad-W Switchgear
Assemblies

vacuum switchgear.
VacClad-W Match and Lineup Cubicles
New manufactured VacClad-W switchgear
structures to match and line up to existing
Westinghouse VacClad-W switchgear.
New VCP-W structures can also connect to
existing non-current Westinghouse indoor
switchgear (types DH, DHP, and VCP) with
a transition section.
New VCP-W Vacuum Breakers
Completely new factory manufactured
VCP-W vacuum power circuit breakers are
available in all published ratings.
Renewal Parts
Cutler-Hammer offers an extensive inventory
of newly manufactured renewal parts
for VCP-W switchgear structures and
breakers.

switchgear were furnished with high grade
glass polyester insulation as standard.
Optional insulation upgrades included
cycloaliphatic epoxy insulation for breaker
element insulation (VCP-WSE breakers)
and porcelain insulation for the switchgear
cell contact bottles. VacClad-W switchgear
is manufactured in indoor and in sheltered
aisle and aisle-less outdoor enclosures.

Chronology
VacClad-W switchgear was introduced in
1986 and is the current state-of-the-art
Westinghouse switchgear product.
The VCP-WSE breaker with special
cycloaliphatic epoxy insulation and the
27 kV VCP-W rating were introduced in
1990. IEC VCP-W ratings were introduced
in 1991. 38 kV was introduced in 1995.
Fluidized Switchgear Bus
Cutler-Hammer offers new fluidized epoxy
bus – insulated bus to replace existing
switchgear phase bus insulation.
