Multicore XLPE Cable Waterproof Armoured Low Voltage Copper PVC

MultiCore XLPE Waterproof Armored Low Voltage Copper PVC Cable - Technical Specification

1. Overview

The multicore XLPE waterproof armored low voltage Copper PVC Cable is specifically designed for power distribution systems requiring robust mechanical protection and moisture resistance. Featuring Copper Conductors, cross-linked polyethylene (XLPE) insulation, metal armor, and PVC outer sheath, this cable delivers superior electrical performance while withstanding harsh environmental conditions. It is widely used in industrial plants, underground installations, and outdoor power distribution networks.

2. Cable Construction & Material Properties

2.1 Conductor

• High-purity Copper Conductors:

• Low resistivity for efficient power transmission with minimal energy loss

• Excellent Flexibility and fatigue resistance for multicore stranded configuration

2.2 Insulation (XLPE)

• Cross-linked polyethylene insulation:

• High temperature resistance (90°C continuous, 130°C short-term)

• Superior dielectric strength with resistance to corona and partial discharge

• Chemical and moisture resistance for harsh environments

2.3 Waterproofing System

• Radial water barrier:

• Aluminum-polyester laminate or water-blocking compounds prevent longitudinal water penetration

• Additional waterproof coating between armor and outer sheath

2.4 Armoring

• Steel wire/tape armor:

• Mechanical protection against crushing, impact, and rodent damage

• Provides grounding capability and EMI shielding

2.5 Outer Sheath (PVC)

• PVC outer sheath:

• Abrasion and UV resistant for outdoor/direct burial applications

• Flame retardant (compliant with IEC 60332)

• 
  

3. Electrical & Mechanical Characteristics

• Rated voltage: 0.6/1 kV (low voltage systems)

• Temperature range: -20°C to +70°C (installation), -40°C to +90°C (operation)

• Minimum bending radius: 12× cable OD (unarmored) or 15× (armored)

• Waterproof rating: IP67 (temporary immersion) or IP68 (permanent underwater)

4. Typical Applications

• Industrial power distribution in plants, mines, and ports

• Underground installations in tunnels and subways

• Renewable energy projects (solar/wind farms)

• Building electrical systems with high fire safety requirements

5. Key Advantages

1. High reliability: XLPE insulation ensures long-term stability

2. Environmental resistance: Waterproof and armored construction

3. Safety compliance: Meets IEC and GB/T standards

4. Cost-effective: Low maintenance requirements

6. Selection & Installation Guidelines

• Selection: Consider current rating, ambient temperature and mechanical stress

• Installation: Maintain proper bending radius; armor must be properly grounded

• Maintenance: Regular inspection for sheath damage and armor corrosion
