Energy utilities use their own specifications, but they always comply with Brazilian standards. The material and flexibility class of the conductor, the insulation and covering polymers and the armouring section vary between them, as do the presence of moisture blocks and other requirements. We are always ready to develop new cable design solutions, such as the Eproflex Jumper 90 cable for provisional medium-voltage connections, the Indugrex-TR Rural cable for quality medium-voltage power distribution in rural areas and the Ecopower cable manufactured with lead-free HEPR insulation. Bare aluminium cables with or without a steel core, multiplexed insulated cables for low or medium voltage and Indugrex-TR anti-kickback polyethylene covered cables for medium voltage are available for installation in overhead networks.
