PPI HDPE CONDUIT SAMPLE COLLECTION PROGRAM
PPI's Power & Communications Division (PCD) has launched a research program to analyze "used" HDPE* power
conduit for research about long-term performance and durability.
*HDPE conduit is flexible, in long lengths, in various colors - not to be confused with rigid PVC conduit (gray).
It is well-known that HDPE conduit is an excellent material for housing and protecting electrical power cables,
with benefits including long lengths without joints, high strength and durability, impact resistance, and
installation toughness. This research effort will increase the body of knowledge about the product's
long-term durability for power applications.
Through the PPI HDPE Conduit Sample Collection Program
, PPI is reaching out to utilities, contractors and
other users and seeking assistance with collecting samples of "used" HDPE power conduit. Specifically, the
program is seeking samples of HDPE conduit that have been in service for 5, 10, 15, 20 years, or more.
Ideal samples for this program have been buried in the ground, carrying power cables of any voltage. Any
diameter or SDR is useful. Perhaps the conduit is being removed due to damage, re-routing, or any other reason.
Some basic information about the location, use and estimated lifetime of the used conduit samples
will be collected using a form
Collected samples will be analyzed at laboratories in a series of physical and chemical tests. When complete,
the findings will made available to the community. This information may benefit utilities when forecasting for future replacements.
