Abstract

The main reason of failure for electric cables with polyethylene insulation which are in service under mechanical load at high temperatures is cracking of shells and insulation. Resistance to cracking is governed by cold resistance. The latter is defmed as the temperature at which cable bending leads to an integrity loss of a shell or insulation. In its turn, cold resistance correlates with a permolecular structure of polyethylene. In this contribution, a nondestructive method for estimating the service life of electrical cables with polymer insulation is considered. The method is based on using the above mentioned correlations.
