Product Introduction
Structural Feature
Structural Feature IdentificationConductor: 3 groups of compacted stranded copper conductors, with 1 group additionally leading out 2 thin copper wires (usually grounding wires or monitoring wires).
Insulation: Gray cross-linked polyethylene (XLPE) insulation layer, a typical insulation material for medium and high voltage cables.
Shielding: Each core is wrapped with a copper tape shielding layer to homogenize the electric field and conduct fault current.
Cabling and Sheathing: The 3 cores are cabled and filled, with an armor layer (steel tape/steel wire) and a black outer sheath visible on the outer layer, providing mechanical protection and waterproof performance.
product key technologies
Excellent Electrical Performance
- XLPE insulation offers high voltage resistance and low dielectric loss, ensuring stable long-term operation for 6kV~35kV medium/high-voltage power transmission.
- Copper tape shielding per core homogenizes the electric field, preventing partial discharge and extending insulation lifespan.
Strong Mechanical & Environmental Resistance
- Steel tape/armor + outer sheath provide robust protection against compression, impact, and dragging, suitable for direct burial, tunnels, and cable trays.
- Wide operating temperature range (-40°C~90°C), UV resistance, and anti-aging properties for long-term outdoor/underground use.
- Multi-layer sheathing blocks moisture effectively, avoiding water tree aging and adapting to damp environments.
Efficient Transmission & Easy Installation
- Compacted copper conductors deliver higher conductivity and lower skin effect, offering larger current-carrying capacity than aluminum cables of the same size.
- 3-core structure is compact and easy to bundle/fix, saving installation space with clear phase identification via color marks.
- Balanced flexibility allows easy bending and on-site routing while maintaining mechanical strength.
Enhanced Safety & Low Maintenance
- Optional flame-retardant (ZB/ZA) or fire-resistant (NH) versions meet fire safety standards and reduce fire risks.
- Shielding + grounding wires (extra thin copper wires in the image) enable quick fault location for grounding issues.
- Designed service life of over 30 years under normal conditions, minimizing replacement and maintenance costs.
Wide Adaptability & Cost-Effectiveness
- Ideal for high-power transmission in urban grids, industrial plants, substations, and new energy power stations (PV/wind).
- Higher initial cost is offset by superior reliability, long lifespan, and low maintenance, resulting in lower total lifecycle costs.
Urban Power Grid & Infrastructure
- 10kV/35kV urban distribution networks (direct burial, tunnels, cable trenches).
- Municipal projects: metros, airports, ports, and large commercial complexes.
- Power transmission between substations and to load centers.
Industrial & Energy Sectors
- High-power supply for heavy industries (steel, petrochemical, cement, paper).
- Collector lines and grid connection for new energy power stations (PV, wind).
- High-voltage power supply for mining and metallurgy, resistant to impact and harsh environments.
Special & Outdoor Environments
- Power supply for transportation infrastructure (highways, bridges, tunnels).
- Offshore platforms and port terminals with weatherproof and waterproof requirements.
- Temporary high-power supply for large events or emergency rescue (with armored protection).
Material Introduction of 3-Core Copper XLPE Insulated High-Voltage Power Cable (Armored Type)
1.Conductor Material
- Material: Electrolytic Tough Pitch (ETP) Oxygen-Free Copper
- Features: High conductivity (≥99.95% IACS), low resistivity, and excellent mechanical strength. Compacted stranding reduces skin/proximity effects and improves current-carrying capacity.
- Advantage: Higher ampacity and longer service life compared to aluminum conductors.
2.Insulation Material
- Material: Cross-Linked Polyethylene (XLPE)
- Features: Three-dimensional network structure formed by cross-linking, with a rated temperature of 90°C, high dielectric strength, low loss, and excellent aging/corrosion resistance.
- Advantage: Superior electrical performance and long-term stability for medium/high-voltage applications over traditional PVC insulation.
3.Shielding Materials
- Semi-conductive Shielding: Eliminates conductor tip discharge and homogenizes the electric field around the XLPE insulation.
- Copper Tape Shield: Wrapped around each core to conduct fault currents, shield electromagnetic interference, and serve as a grounding monitoring path.
4.Filling & Binding Tape
- Filling: Flame-retardant polypropylene or jute fills gaps between cores, ensuring roundness and mechanical cushioning.
- Binding Tape: Non-woven fabric or polyester tape binds cores to prevent loosening and provides a smooth base for armoring.
5.Armoring Material
- Steel Tape Armor (STA): Excellent compression resistance, ideal for direct burial and cable trench applications (e.g., YJV22).
- Steel Wire Armor (SWA): High tensile strength, suitable for vertical shafts and underwater installations (e.g., YJV32).
- Function: Provides robust mechanical protection against external pressure, impact, and dragging.
6.Outer Sheath Material
- PVC Sheath: Good flame retardancy, cost-effective, weather and chemical resistant.
- HDPE Sheath: Superior low-temperature resistance, waterproofing, and UV resistance, ideal for outdoor/underground environments.
- Function: Acts as the final barrier against moisture, corrosion, and abrasion, protecting internal components.
