OVERVIEW


Application

Single core or multi-cores aerial Cables for voltages about 1kv~35kV.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.

Standard

GB/T14049,ICEA S-121-733,BS-EN-50397.

Product Properties

Conductors are stranded,circular compressed aluminum, aluminum-alloy, copper.

Conductor screen is the extruded Semi-conducting conductor shield in Black.

Insulation is cross-linked polyethylene (XLPE) or HDPE.

When laying the cable,ambient temperature is not lower than -20℃.

During short circuit(max.lasting time is not more than 5 seconds),

the max.temperature for XLPE cable is not more than 250℃.

the max.temperature for HDPE cable is not more than 150℃.

the long-time permissible working temperature of cable conductors,

For XLPE cable,it is max.90℃.

For HDPE cable,it is max.75℃.
