By Nwokorie F. O., Ossia, C. V., Big-Alabo, A.
The reliability of ignition system performance is directly influenced by the quality of high-voltage cables that deliver electrical pulses to spark plugs and other ignition components. Conventional ignition cables, typically constructed with single-layer polymeric insulation, are limited by thermal degradation, partial discharge susceptibility, and reduced electromagnetic compatibility. The RAHEF Ignition System introduces a composite wall insulated cable solution, designed to address these limitations through multilayer insulation architecture that combines high dielectric strength, thermal stability, and enhanced mechanical endurance. This study investigates the design principles, material composition, and performance characteristics of RAHEF composite ignition cables, with emphasis on dielectric behavior, partial discharge inception, mechanical robustness, thermal aging, and electromagnetic interference suppression. Comparative analysis with conventional single-insulated cables highlights the superior breakdown voltage, durability under harsh automotive conditions, and reduced spark-plug wear offered by composite insulation systems. The findings demonstrate that RAHEF composite wall cables significantly improve ignition reliability, reduce maintenance requirements, and extend service life, thereby providing a cost-effective and technologically viable solution for modern automotive and industrial ignition systems. The study concludes that composite insulation technologies, as applied in the RAHEF ignition system, present a strategic advancement in ignition cable design. Further research is recommended to optimize material combinations, ensure large-scale manufacturability, and establish standardized performance benchmarks for industry adoption.
