Low Voltage Cables IEC Standard

Product Introduction

1. IEC 60502-1 0.6/1kV Armoured PVC Insulat
2. IEC 60502-1 0.6/1kV XLPE Insulated PVC Armoured Cables
3. IEC 60502-1 0.6/1kV XLPE Insulated PVC Sheathed Cable Multi Core

Application

These power cables are used for electricity supply in low voltage installation systems. They are well adapted to underground use in industrial applications with an additional mechanical protection. They are suitable for laying Indoor, tunnel, cable trench, shaft or buried laying. The cable can withstand mechanical external forces and a certain tensile force, it widely used in transformer stations, electric power plants and industrial plants.

Construction

• Conductor: Copper, class 1 or class 2, solid or stranded, circular or circular compacted conductors
• Insulation: Cross-linked polyethylene XLPE
• Filler: Non-hygroscopic material
• Binder: Non-hygroscopic material
• Inner sheath: Polyvinyl chloride PVC
• Armour: Steel wire
• Binder: Non-hygroscopic material
• Outer sheath: Polyvinyl chloride PVC

Chaircteritics

Good electrical and mechanical properties. Cross-linked polyethylene insulation allows greater power capacity under any operating condition, minimum dielectric losses, high insulation resistance. The PVC outer sheath allows an adequate resistance to oil and abrasion.
