Comparison of cross-linked polyethylene compounds by short-term electrical and thermal tests

Abstract

Tests procedures for short-term electrical, thermal and multi-stress characterization of cross-linked polyethylene insulating materials for high-voltage cables are presented. Electric strength and endurance tests at high electric field enable characterization of insulation performance under electrical and thermo-electrical while an analytical technique, based on stability measurements, permits thermal endurance to be investigated. These test procedures are applied to two XLPE compounds.
