Key features
• 34.5 kV, outdoor
• 200 kV BIL, 60 Hertz
• Electrical clearances:- Strike: 25.25" (387 mm)- Creep: 38.00" (965 mm)
• Approximate weight: 125 lbs. (57 kg)
Application
The VOY-20 outdoor voltage transformer is designed
for solid state relaying and electronic metering where
the burden of the device is negligible.
Construction features
For insulation and protection, the assembly is cast in
hydrophobic cycloaliphatic epoxy (HCEP) using
automatic pressure gelation. The HCEP material
offers superior arc track, ozone, and ultraviolet
resistive properties while maintaining physical
strength. The hydrophobic properties of HCEP ensure
a high level of performance in wet, polluted or coastal
environments.
Terminals
Electro-tin plated copper primary line terminals
accommodate #10 to 250 MCM conductors. Clamp
type secondary terminals accommodate #14 through
#3 wire. A ground terminal is also provided for
grounding the secondary circuit at the transformer.
Junction box
The junction box has a 1" conduit hub on either end
and a knock out for a 1" conduit fitting on the bottom.
It can be easily detached, simplifying installation and
change-out procedures.
Baseplate
The base is constructed of corrosion-resistant
aluminum and is secured to the encapsulated
base support.
Mounting
The VOY-20 can be mounted in upright, cantilever, or
upside-down positions. Stress relief devices should
be used to support cable connections where
applicable. For more installation guidance, refer to
medium voltage outdoor voltage transformers 5 -
34.5 kV instructions for installation, use, and
maintenance.
Test reports
Test reports are stored electronically and can be
e-mailed in various formats at the time of shipment.
Standards
This unit meets or exceeds all requirements of IEEE
C57.13 and can be tested to other standards
as requested.
