A Survey of Electrical Materials Counterfeiting in Bayelsa State: A Case Study of Yenagoa Local Government Area
Electrical cables are the bedrock of every electrical wiring and installation. Therefore, the utilization of counterfeit or substandard electrical cables, during electrical wiring and installation can create a lot of electrical and economic tragedies. In this study, some essential properties (cable size, electrical resistivity, and flame retardant) of electrical cables solid in Bayelsa state were determined, according to NIS approved methods. Four commonly used electrical cables (1 mm2, 1.5 mm2, 2.5 mm2, and 4 mm2) in Bayelsa State were sampled for this study. Results obtained from the study revealed that most of the electrical cables sold within the Yenagoa metropolis of Bayelsa State, fell below International Standards. The result revealed that only 58% of the 1 mm2 cable, 43% of the 1.5 mm2 cables, 62% of the 2.5 mm2 cable,s and 46% of the 4 mm2 cables met the NIS recommended sizes for electrical cables. In terms of the electrical resistivity of the cables, the study revealed that most of the cables failed to meet the NIS recommendations. The resistivity of 45% of the 1 mm2 sampled cable, 39% of the 1.5 mm2 sampled cable, 52% of the 2.5 mm2 sampled cable, and 33% of the 4 mm2 sampled cable, were above the maximum limits approved by the Nigeria Industrial Standard. The high resistivity observed in the cables can lead to an electrical fire, through high-temperature buildup within the cable. Furthermore, it was observed that most of the cable insulators were made from good fire retarding materials. It results revealed that 92% of the 1 mm2 cable, 93% of the 1.5 mm2 cables, 89% of the 2.5 mm2 cable,s and 87% of the 4 mm2 cable insulators had flame retarding characteristics. Results obtained from this study can be used as a guide by standard regulatory agencies, to monitor the sales of electrical cables in the state, since most of the cables sampled in this study fell below National and International standards.
