The purpose of this study is to determine when measurable deterioration of a moisture impervious cable will occur during typical service life. This report covers the initial series of tests on cable removed after five years of service.
Plans are to test cable samples at five year intervals.
The study uses new cable test results as the benchmark. These tests are part of an ongoing testing program to verify the benefits of a moisture impervious cable design. Background Virginia Power has made a major investment in moisture impervious cable. They have installed over eleven million linear feet of moisture impervious cable. Four million feet of this is 1000 kcmil aluminum 35 kV cable.
