Design and implementation of prototype for XLPE cable aging test

The current increase in the demand for electric power and the obligation to comply with the regulations associated with reliability and continuity in the supply, have prompted the manufacturers of electrical conductors to focus on designing their products with special care when considering the electrical properties of the materials. The use of XLPE insulated cables in underground transmission lines in 115 kV systems has increased in cities due to urban, environmental and reliability requirements. This is also related to the fact that air networks are exposed to external factors such as lightning, comets, vegetation, animals, etc., which can affect their functioning failures. The fact of using transmission technology with insulated cables gives rise to the need to evaluate the behavior of its components when operating in the long term. To achieve this, it is necessary to implement a procedure that allows analyzing the aging of these elements when operating in load cycles for a certain period of time. Thus, this document presents the development of a prototype that allows conducting the aging test to conductors isolated by XLPE.
