Abstract
In the design of wiring systems for use in public utility facilities, it is important to pay particular attention to ensuring the integrity of cables at high temperatures. At the moment of a fire breaking out, it is important to reduce the spread of flames as much as possible as well as decrease the danger of the release of toxic fumes. These requirements are fulfilled by using fireproof and self-extinguishing cables, of which the insulating coat is made from halogen-free and slow-burning materials. In this type of product, Cu-ETP grade copper is mainly used as a conductive material. However, because of the susceptibility of Cu-ETP grade copper to hydrogen embrittlement at high temperatures, it is usually replaced by oxygen-free copper. The lack of oxygen in copper removes the danger of hydrogen disease, thereby ensuring that the cables operate as long as possible in the event of a fire. The conducted tests are explained in this paper, of which the main aim was to evaluate the resistance of Cu-ETP and Cu-OFE grade copper conductors, both with and without halogen-free isolation to hydrogen disease. It describes the resistance properties of cables and observes their structure after the process of annealing at different temperatures - these being the essential ingredients in evaluating the integrity of the cables at high temperatures.
