Temporary Over-Voltage Capability
Hubbell Power Systems arresters are gapless and consist of a column of metal-oxide blocks connected between
line and ground. The blocks can withstand a significant power frequency overvoltage for a limited time, depending on the magnitude of any immediately preceding surge duty. This duty can be the result of switching surges
on higher voltage lines, or from other sources. The temporary overvoltage capability can be determined from the
TOV curve. The prior duty curve is based upon absorption of rated energy immediately preceding application of
the overvoltage.

Polymer Housed Arresters
(Type PVI-LP)
Construction & Features
MOV blocks are encased within
a tightly woven fiberglass braid
impregnated with epoxy resin.
Silicone dielectric compound fills
the interface between fiberglass
and rubber housing to render a
void-free and hydrophobic assembly.
Design prohibits leakage and
pumping of air across hermetic
seals in order to eliminate moisture ingress, a cause of arrester
failure.
Polymer housings are resistant
to impact damage and will not
shatter in case of a failure.
Typically less than half the weight
of comparable porcelain arresters. This makes transportation,
handling and installation much
easier.
Small line end hardware allows
close spacing.

Note that alternate builds with additional creepage distance are shaded.
For non-catalog polymer arresters that require higher creep distance or special application
please consult your Hubbell Power Systems representative.
