Aerial Insulated Cable (IEC 60502-2 / GB/T14049)

Introduction

Application
Aerial Insulated Cables with voltages of 10kV.The products primarily used for the distribution of electrical energy under normal conditions of overhead (aerial) installations.The conductors must be installed on insulators and/or spacers adequate for the service voltage. The user may want to give consideration to the dielectric compatibility of the covering, insulator, spacer etc.
Description
The conductors are stranded,circular compressed aluminum, aluminum-alloy, copper. The conductor screen is the extruded Semi-conducting conductor shield in Black. And the outer Insulation is mainly thermoplastic polyethylene (PE) or cross-linked polyethylene (XLPE) in Black with Weather or UV resistant. This standard covers both thermoplastic and cross linked polyethylene constructions, rated for 75°C or 90°C normal service temperature.
Specification
GB/T 14049 (Equal to IEC 60502-2) Aerial Insulated Cables For Rated Voltage of 10kV
