1. Product Introduction
The YJV32 Steel Wire Armored (SWA) Power Cable is a heavy-duty power distribution solution designed for environments where maximum mechanical protection and high tensile strength are non-negotiable. Unlike standard steel tape armor, the SWA structure uses galvanized steel wires that allow the cable to withstand significant longitudinal tension, making it the premier choice for vertical installations, deep shafts, and underwater crossings.
Model: YJV32 (SWA)
Voltage Rating (U₀/U): 0.6/1kV up to 26/35kV
Main Feature: High tensile strength for vertical and high-load environments.
Standards: IEC 60502-1, BS 5467, AS/NZS 5000.1, GB/T 12706
2. Structural Composition
[Image: Cross-section of multi-core YJV32 Steel Wire Armored Cable]
Conductor: High-purity plain annealed copper, Class 2 stranded compacted circular or sectoral.
Insulation: XLPE (Cross-linked Polyethylene) – providing excellent thermal stability (90°C) and electrical insulation.
Inner Liner / Bedding: Extruded PVC or PE layer to create a smooth cylindrical surface and protect cores from the wire armor.
Armor: Galvanized Steel Wire Armor (SWA) – a dense layer of galvanized steel wires applied helically to provide 360° protection and superior pulling strength.
Outer Sheath: Heavy-duty PVC or PE, offering high resistance to abrasion, moisture, and chemicals.
3. Technical Parameters
Feature Specification / Value Max. Conductor Temp. 90°C (Normal) / 250°C (Short Circuit) Tensile Strength Superior (Designed to support cable self-weight in vertical runs) Armor Coverage ≥ 90% (Galvanized steel wires) Min. Bending Radius Multi-core: 15 × Overall Diameter (OD) Operating Environment Submerged, vertical shafts, and high-impact industrial zones Flame Retardancy Optional to IEC 60332 Class A/B/C 4. Key Advantages: Why SWA?
Vertical Tension Load: SWA is the only armored cable capable of supporting its own weight over long vertical distances (e.g., high-rise cable wells or mine shafts) without stretching or damaging the internal conductors.
Extreme Impact Protection: The thick steel wire layer provides a massive physical barrier against crushing, accidental excavation, and falling debris.
Anti-Corrosion Durability: Every steel wire is heavily galvanized, ensuring the armor remains intact even in damp, corrosive, or marine environments.
Underwater Reliability: Frequently used in river crossings or marshy ground where cables are subject to shifting loads and water pressure.
5. Primary Application Scenarios
High-Rise Buildings: Vertical power risers in skyscrapers and residential towers.
Mining & Tunnels: Main power feeders for underground mines and transport tunnels.
Marine & Infrastructure: River/sea bed crossings and bridge installations where the cable may be suspended.
Industrial Plants: Heavy-duty outdoor wiring in steel mills, refineries, and power generation hubs.
6. Core Configurations & Technical Notes
Single Core: For AC systems, we use AWA (Aluminum Wire Armor) to prevent magnetic heating (YJV42).
Multi-Core (2, 3, 4, 5 cores): Standard SWA for high-load power distribution.
Customization: Available with LSZH (Low Smoke Zero Halogen) sheaths for public safety in enclosed shafts.
