The civil construction and infrastructure market demands safety and quality, with compulsory certification by INMETRO for some product families. The use of disbitolated or difficult to install cables is not permitted. Duflex 750 V cables, PVC insulated, and Eproflex 90 0,6/1 kV, insulated in ethylene-propylene rubber (HEPR) and covered with PVC are the most common. But the product line is complete, including also Indugrex cables, insulated in cross-linked polyethylene (XLPE) or Atox Flex (halogen-free) in 750 V and 0,6/1 kV versions. The Atox version is of compulsory application in places of great affluence of people, defined in NBR 13570 standard.
Special cables for infrastructure projects, such as Airport runway lighting cables or Fire Alarm cables are also available.
In medium voltage the most cost-effective cable is the Epronax Slim 105, insulated in ethylene-propylene rubber for operation at 105 °C and reduced insulation thickness.
The cables can be offered with copper or aluminium conductor, for voltages up to 138 kV.
