The Duplex Service Drop Cable manufactured by Zhongdong Cable is designed for overhead low-voltage service connections between utility distribution lines and residential, commercial, or small industrial electrical installations.
The cable consists of two insulated aluminium conductors twisted together, typically including one phase conductor and one neutral conductor. The compact aerial design provides a reliable and economical solution for overhead power supply applications while reducing installation complexity compared with traditional open wire systems.
With durable insulation and weather-resistant construction, Duplex Service Drop Cable is suitable for outdoor installations exposed to sunlight, moisture, and changing weather conditions.

It is mainly used for connecting low-voltage overhead distribution lines to residential or commercial electrical service entrances.
Duplex cable contains two conductors, usually one phase and one neutral, while Triplex cable contains three conductors, typically two phase conductors and one neutral.
Yes. The cable is designed for outdoor aerial installation and uses weather-resistant insulation materials suitable for long-term exposure.
Aluminium offers a good balance between electrical conductivity, weight reduction, and cost efficiency, making it suitable for overhead applications.
XLPE is commonly used for higher temperature and better outdoor performance, while PE insulation can be selected for specific project requirements.
For XLPE insulated designs, the conductor can operate continuously at up to 90°C under normal conditions.
Common accessories include service clamps, connectors, suspension fittings, and pole attachment hardware selected according to installation requirements.
