Over the past two decades, the
PPL Field Liner has
undergone wide ranging tests to
confirm it’s efficacy as a barrier
to protect wooden poles from decay &
termite attack.
The most
important benefit of the PPL Field
Liner is that by preventing
preservatives leaching out of the
pole and into the environment,
preservative retention levels are
maintained at standard levels and
preservative penetration actually
increases, so protecting both the
pole and the environment. As an
additional but significant benefit,
the Field Liner prevents the pole
from being attacked by or infested
with termites, a clear and present
danger in many parts of the world
(as an example, the onslaught of the
Formosan termite in the southern
coastal regions of the USA is
causing substantial damage to
Utility Poles and wooden structures
in general at a huge economic cost).
The test
program over the years, historically
funded by Biotrans UK, has sought to
prove the efficacy of the PPL Field
Liner through both internal and
external testing. Academic
institutions such as Oregon State
University, University of Hawaii and
Mississippi State University are
world renowned wood protection
research establishments and Electric
Utilities rely on organisations such
as Electric Power Research Institute
(EPRI) to undertake major research
projects to the benefit of the whole
industry.
As a
result of this comprehensive testing
programme over many years, product
innovation and stepwise refinement
has resulted in the current form of
the PPL Field Liner, a one piece
sleeve allowing quick and easy
installation at the point of pole
setting.
Importantly, the PPL Field Liner has
been implemented in ‘the real world’
by major Utilities on two continents
and their practical experience has
shown the effectiveness of the Field
Liner as an economic and
environmental solution to utility
pole decay and pollution.
