15kV-25kV-35kV-46kV Multi-layer Covered Aerial MV spacer cable
Covered Conductors - Spacer Cable Systems
Description: Covered conductors consist of stranded hard drawn aluminium conductors with either one, two or three extruded layers depending on the voltage rating. Covered conductors are available in black or gray depending on visual preference.
Application: Covered conductors are designed to be used in spacer cable systems. Conductors are suspended from the messenger using Hendrix polyethylene spacers. Covered conductors are rated for continuous operation at 75°C.
Spacer Cable STRUCTURE:
Conductor: All Aluminum (AAC) - 1350-H19 aluminum
Conductor Screen: Semiconducting Polyethylene
Insulation: Natural Low Density Polyethylene / XLPE
Jacket: Black or Gray Track Resistant High Density Polyethylene

Advantages of spacer cables and comparing with medium voltage Aerial Bundled cables:
1 - Troubleshooting Aerial Bundled cables is difficult due to complexity and so is to repair whereas in spacer-cable network this issue has been addressed and solved
2 - The cost of constructing an aerial spacer cable network equals %60 of the network with Aerial Bundled cables
3 - Spacer cable distribution networks are simple and do not require special fittings, equipment or instructions in comparison with Aerial Bundled cables networks
4 - Acquiring splitting and attaching a transformer in medium voltage Aerial Bundled cables networks is extremely difficult whereas in spacer cable networks this issue has been alleviated and improved
5 - Spacer cables are lighter than Aerial Bundled cables and so they require less pole stability power
The advantages of spacer cables with Medium voltage overhead covered conductors:
1 - All aluminum conductors can be utilized
2 - Extra lightning protection equipment are not needed
3 - Insulators are not needed
4 - Adjacency band limitations are decreased
5 - Multiple feeders can be fitted on one pole
6 - Can be passed through large spans
