Abstract

The need to carefully assess the quality of electrical cables to ascertain it meets the required standard is highly important because it seeks to determine the mechanical and electrical properties and behaviours of cables prior to usage. To a large extent it also helps in avoiding hazards as a result of low or poor quality products. In this work, cable samples were collected from five (5) Wire and Cable companies in Nigeria. The samples were subjected to quality, uniformity and other tests. This was done to determine the conformity to the available standards. The conformity of the wire and cable tested were justified by t-test and both 90% and 95% confidence levels.
