MV ABC Aerial Bundled Cable (IEC 60502)
Application
Medium Voltage aerial bundled cables are mainly used for secondary overhead lines on poles,clamped to tunnel walls or as feeders for homes.
Standard
IEC 60502-2---- Power cables with extruded insulation and their accessories for rated voltages from 1 kV (Um = 1,2 kV) up to 30 kV (Um = 36 kV) - Part 2: Cables for rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV).
Voltage
6.35/11Kv, 19/33kV
Construction
| Phase Conductor | Class 2 Circular compacted stranded Aluminum |
| Conductor Screen | Extruded semi-conductive layer |
| Insulation | XLPE (Cross-linked polyethylene) |
