Aerial insulated cables of rated voltages up to and including 1KV

Detailed Product Description

 

Introduction
The products are manufactured by extruding a conductor screen layer, an insulated layer of rough-weather-adaptive XLPE or rough-weather-adaptive black HD-PE or PVC, and an insulation screen layer over the compacted copper/aluminium conductor(no conductor screen layer and insulation screen layer for cables of rated voltage 1kV),with the advantage of simple construction, and excellent mechanical,physical and electrical property as well as fine performance of anti-creeping- discharge, rough-weather-adaptive and creepage-proof. Compared with bare conductor, the product can be laid more closely to save the line gallery, and have less voltage-drop. Above all, the products installed reduce power accidents to insure lives safety.
Standard
The products shall comply with the standards GB12527-90 and GB14049-93.
Applications
The products fit for transmitting line and distributing line of rated voltage 1kV, 10kV and 35kV in tall buildings, traveling development area and wooded tract.
