This is a medium-voltage aerial insulated cable that complies with the IEC 60502-2 standard. It's designed for overhead power distribution at 10kV. Conductors can be made of aluminum, aluminum alloy, or copper, with insulation and a semi-conductive shield. The conductors must be installed on insulators or spacers appropriate for the service voltage.
Applications
This cable is used for the distribution of electrical energy in overhead (aerial) installations. When installing, it is essential to use appropriate insulators and spacers. The dielectric compatibility of all components (covering, insulator, spacer, etc.) should be taken into consideration for the service voltage.
