Desenvolvimento experimental de um forno de ciclo térmico para envelhecimento de cabos elétricos

Abstract

Modern industry is subject to global competition and this scenario demands the highest efficiency from companies. One of the methods used in factories to reduce costs arising from unscheduled production stops is called predictive maintenance. The present work aims to collaborate with the predictive techniques of wear in medium voltage electrical cables. Studying the durability and useful life of conductor cables used in the industrial environment is justiĄed by the search for rational use of material resources. For the task of collecting wear data on the insulating layer of transmission cables, it is necessary to produce aged samples of them to be analyzed. Following this line, an oven with a capacity for 40 simultaneous samples was designed, which produces thermal conditions that accelerate the aging of the cables. The thermal chamber demonstrated satisfactory controllability, being versatile enough for other applications, in different conditions from which it was designed to work.
