25KV Covered Aerial Insulated Cable Multi Layer Tree Cable and
Messenger Supported Spacer Cable ACSR / XLPE / HDPE
Application:
Covered Aerial MV Cable – Installed with other Covered Aerial MV
cables and a supporting messenger through a series of space-
maintaining devices (spacers). The resulting close-proximity
configuration minimizes the amount of space and hardware required
for line installation, particularly useful in congested areas.
The conductor material: AAC AAAC ACSR etc.
Conductor Shield: Semi conducting cross-linked polyethylene
Insulation: Cross-linked polyethylene; Colour : Natural
Sheath: Track resistant cross-linked polyethylene; Colour : Black, Gray
Classification:
Normal operation 90 °C
Emergency overload conditions 130 °C
Short circuit conditions 250°C
Voltage rating :
15 kV phase to phase AC TESTING VOLTAGE : 27 kV for 5 minutes
25 kV phase to phase AC TESTING VOLTAGE: 38 kV for 5 minutes
35 kV phase to phase AC TESTING VOLTAGE: 49 kV for 5 minutes
