Conductor
Cable formed by electrolytic bare copper wires, soft temper, class 2 stranding.
XLPE 90 °C – Thermosetting compound of cross-linked polyethylene.
Numbered or colored black veins
PVC ST2 – Thermoplastic polyvinyl chloride compound, black in color, flame resistant.
Used in fixed power and lighting installations in industrial, commercial and residential buildings, in distribution circuits and terminal circuits, and for lowvoltage underground power lines. Its higher thermal class allows greater current conduction capacity than its PVC equivalent (70 °C).
NBR 7287 – Power cables with solid extruded cross-linked polyethylene (XLPE) insulation for insulation voltages from 1 kV to 35 kV.
NBR NM 280 – Insulated cable conductors.
NBR NM-IEC 60332-1 – Test methods for electric cables under fire conditions –
Part 1: test on a single conductor or insulated cable in vertical position.
