The utilization of bare conductors in aerial power distribution lines, in tree regions leads to frequent disconnections due to eventual contact between tree branches with the conductor.
To solve this problem, NEXANS by its industrial plant at Rio de Janeiro/RJ, manufactures the cross-linked polyethylene covered (XLPE) aluminium cable for medium voltage(35kV).
The XLPE covered aluminium cable - 35kV Voltage Class is constituted by a compact round conductor, composed by aluminium strands, blocked or not, with semi-conductive shielding and with a cross-linked polyethylene (XLPE) covered in black or gray color, with special characteristics to be resistant against electric tracking and UV-rays.
As XLPE is a thermoset material, it enables operation up to 90°C continuously implying in higher ampacity when compared to the thermoplastic materials.
NEXANS covered cable enables an harmonious living between power line facilities and environment.
