Normally 3+1 cores cables is composed of 3 insulated aluminium phase conductors and 1 neutral messenger of AAAC (or ACSR) with or without insulation. The system may consists of additional 1 or 2 insulated aluminium conductors with cross sections of 16 mm² or 25 mm² as public lighting.
ABC cable offers higher level of safety and reliability and lower power losses than bare conductors.
Other important cable characteristics are ultraviolet radiation resistance, high dielectric strength, light and easy to handle.
Aerial Bundle Cable used in overhead power system mainly for public distribution or service as a service drop wire. It offers higher level of safety and reliability and lower power losses than bare conductors.
Voltage Rating of aerial bundled cables is mainly U0/U(Um)0.6/1kV(1.2kV) or 600V (phase to phase).
All the cables are insulated with weather-resistant XLPE, PE or PVC compounds. Normal service conductor temperature rating is of 70°C, 75°C or 90°C, etc.
2.Neutral conductor：AAAC or AAC or ACSR
3.Number of core: 3+1 cores
