Covered Cable (ABNT NBR 11873)

Introduction

Application
Primarily used for overhead service applications such as street lighting, outdoor lighting, and temporary service for construction. To be used at voltages of 1000 volts phase - to - phase or less and at conductor temperatures not to exceed 70°C for polyethylene (PE) and Polyvinyl chloride (PVC) insulated conductors or 90°C for cross-linked polyethylene (XLPE) insulated conductors.
Specification
● GB/T 12527（Equivalent to IEC 60502-1）Aerial Insulated Cables for Rated Voltages up to and Including 1kV
● IEC 60228 Conductors of insulated cables
Construction
Conductor: Conductors are stranded,circular compacted or uncompacted aluminum, copper , aluminum-alloy, ACSR etc.
Insulation: Thermoplastic polyethylene(PE),polyvinyl chloride (PVC) ,cross-linked polyethylene (XLPE),black color,weather and UV resistant.
