Introduction

Ohio Brass introduced the very first U.S. non-ceramic
arrester in 1986 and continues to be the market leader
with a full line of polymer arresters for distribution
voltages. Figure A portrays this broad offering of
arresters for both the IEC and IEEE distribution markets.
The PDV-65 offers cost effective protection for a normal
duty arrester. The PDV-100 serves the IEC Class 1 arrester
market. The newest in the line, Optima adds a new
disconnector which improves system reliability and
increases TOV capability. The PVR-Optima targets cable
applications and the PVI-LP® is our IEC Class 2 offering.
As a market leader in arrester technology since 1950,
Ohio Brass has a proven track record of advanced
arrester technology, distinguished product quality, and
extraordinary customer support that establishes Ohio
Brass as a premier manufacturer of arrester products.

Basic Construction

Each PDV, PVI-LP and PVR arrester is made up of a series
of varistor blocks that are manufactured by Ohio Brass
in our two state-of-the-art plants located in Ohio and
South Carolina. Ohio Brass has many years of experience
and proven ability in manufacturing these Metal Oxide
Varistors (MOVs), and this in-company capacity allows us
to fully control the quality and manufacturing processes.
These MOVs dictate the performance characteristics of
the arrester and are locked in place with tightly wound
layers of fiberglass filament impregnated with epoxy
resin.

Polymer Housing

The arrester housing is made from our proprietary blend
of ESP™ silicone alloy. In addition to ESP™’s exceptional
performance as an insulator material, ESP’s properties
have been confirmed in a series of performance tests
that include tracking resistance, contamination, aging,
and seal design.

Mounting

The PDV, PVR and PVI-LP arresters can be used with all
standard mounting arms and brackets. They are also
supplied with all the necessary fasteners, isolators, and
terminal attachments. A specially designed fiberglassfilled
polyester insulating bracket, with integrated disconnector,
along with optional mounting brackets such
as the cross arm or transformer bracket, enable mounting
options that best suit every individual customer.
