YJV vs YJV22 vs YJV32 Core Technical Comparison
| Technical Feature | YJV Cable (Standard Type) | YJV22 Cable (Steel Tape Armored) | YJV32 Cable (Steel Wire Armored) |
|---|---|---|---|
| Full Name | XLPE Insulated PVC Sheathed Copper Power Cable | XLPE Insulated Steel Tape Armored PVC Sheathed Copper Cable | XLPE Insulated Steel Wire Armored PVC Sheathed Copper Cable |
| Armoring Material | None (Unarmored) | STA (Double Steel Tape Armor) | SWA (Galvanized Steel Wire Armor) |
| Crush & Radial Resistance | Low (Requires conduit/pipe protection if under pressure) | Excellent (Safely withstands heavy external crush and soil pressure) | Moderate to High (Resists lateral crushing and rock impact) |
| Tensile Strength (Pulling Force) | Standard (Cannot handle continuous vertical longitudinal stress) | Low (Metallic tapes may slip or unwrap under high tension) | Superior (Withstands extreme longitudinal pulling forces and heavy drops) |
| Bending Radius & Flexibility | Smallest (Highly flexible, easiest to install in tight raceways) | Larger (Relatively stiff due to overlapping continuous steel tapes) | Largest (Stiftest configuration due to full perimeter heavy steel wires) |
| Primary Installation | Indoor cable trays, aerial brackets, concrete ducts, solar PV frames | Direct underground burial, areas prone to ground shifting or external impact | Vertical shafts, deep mining wells, high-drop towers, underwater/marsh burial |
Superior Tensile Strength: The interlocking galvanized steel wire armor (SWA) absorbs massive longitudinal pulling forces, preventing conductor stretching or breakage during vertical drops.
Heavy Mechanical Protection: Shields the inner core from physical impact, moving soil stress, sharp rocks, and heavy construction equipment during long-term deep burial.
Excellent Thermal Integrity: The cross-linked polyethylene (XLPE) core allows continuous normal loading at temperatures up to 90°C and short-circuit thermal safety up to 250°C.
High Conductivity & Minimal Loss: Premium copper conductors ensure high line stability and minimal voltage drops, optimizing power transmission over extensive, complex cable routes.
Application
Vertical Shafts & High-Drop Zones: The global industry standard for installation inside high-rise building vertical risers, deep-level mining shafts, and sharp hillside declines.
Direct Buried Infrastructure: Laid directly in rugged underground trenches where severe earth shifting, heavy backfill, or lateral tectonic pressures occur.
Marine & River Crossings: Ideal for underwater marsh crossings, harbor power grid links, and tidal zone direct burial where water current tension is present.
Heavy Industrial & Grid Networks: Main electrical feeders routing power across utility-scale power stations, metallurgical yards, and automated industrial substations.

FAQ
1. Why is Galvanized Steel Wire Armor (SWA) indispensable for YJV32 copper power cables?
Superior Longitudinal Tensile Strength:
The ’32’ in YJV32 signifies a heavy-duty Galvanized Steel Wire Armored (SWA) layer, providing immense longitudinal tensile strength. This design is essential for vertical installations in high-rise buildings and deep mining shafts to prevent conductor stretching under its own weight.
2. What are the metallurgical and structural advantages of the conductors used in your YJV32 cable?
Premium Conductivity & Thermal Limits:
Our YJV32 cables feature high-purity (99.99%) Oxygen-Free Copper (OFC) configured as Class 2 stranded compactors, offering superior conductivity and low impedance compared to low-grade alternatives. Combined with cross-linked polyethylene (XLPE) insulation, they ensure high-temperature resistance and stable power transmission.
3. Can the YJV32 SWA cable family support medium and high-voltage substation networks?
Broad Voltage Scaling & Grid Reliability:
Yes, the YJV32 range scales from low-voltage (0.6/1 kV) to medium-voltage, including 8.7/15 kV and 26/35 kV. These cables provide robust reliability for industrial substations and utility-scale power projects.
4. How does the YJV32 armor cable perform in damp, marine, or river-crossing environments?
Impenetrable Environmental Shielding:
The combined PVC outer jacket and moisture-resistant insulation provide an impenetrable barrier against environmental stress, water ingress, and chemicals. This design is critical for maintaining dry and protected cores in challenging environments.
5. What are the manufacturing standards and wholesale logistics packaging for bulk YJV32 orders?
Global Engineering Compliance & Secure Shipping:
ZHONGYI CABLE manufactures YJV32 products adhering to IEC 60502 and GB/T 12706 standards. Bulk orders are securely packed on large steel-wooden drums to ensure integrity during international transit.
