The Transmission Department requested the Research Center to evaluate
115 kV and 230 kV Polymer insulators. Samples of these insulators from
four manufacturers were submitted for the test program. Representative
samples of each type submitted were evaluated for RIV, tensile strength;.
fiberglass rod porosity, rod to rubber adhesion, and flamability. Samples
of 230 kV field aged insulators from one manufacturer were also submitted
and were included in the RIV and tensile strength portions of the test
program.
The samples from all manufacturers performed similarly for rod
porosity and flamability. Since one manufacturer makes no effort to bond
the rubber to the rod, his adhesion was very low compared to the other
three with similar bonding strength. The tensile strength and RIV test
results varied between manufacturers and designs.
The field aged 230 kV insulators were shown to have a significant RIV
level at normal operating voltage. However, the addition of a corona ring
reduced the RIV to an acceptable level.
