NBR 8182 Multiplex Aluminum Cable /Preassemble Cable For Brazil
DESCRIPTION of Preassemble Cable
The aerial bundled cables designed for overhead distribution lines have all conductors made of aluminum
1350 and insulated with XLPE. Phase and neutral cores are laid up in a bundle with a left hand lay. Cables are rated at 0.6/1 (1.2) kV and conform to NBR 8182.
The main advantage of aerial bundled cables include:
1 Ease of erection and stringing
2 Practically no tree – trimming required
3 Less maintenance
CONSTRUCTION of Preassemble Cable
1 Conductor (For both phase and neutral) :
The conductors shall be of aluminum 1350 wires and are compacted circular stranded.
2 Insulation :
The conductors shall be extruded with Cross-linked Polyethylene (XLPE) material as insulation. Each
phase core is marked with numerals and letters 1 ONE, 2 TWO or 3 THREE and with one rib,two ribs or
three ribs to denote the phases. The neutral core carries equally spaced ribs right round the circumference.
