Product Specification

YJV 0.6/1kV Copper PVC Sheath Xlpe Power Cable 3*95mm2 70mm 3core 3x6mm Steel Tape Armoured Cable

This YJV steel tape armoured power cable is designed for fixed power distribution installations with a rated voltage of 0.6/1kV. The cable features a mixed conductor configuration comprising three main power cores (3×95mm²), a reduced neutral core (70mm²), and three control/auxiliary cores (3×6mm²)—all housed within a single XLPE-insulated, steel tape armoured structure with a black PVC outer sheath.

This mixed-section design is widely adopted in industrial and infrastructure projects where power transmission and auxiliary control functions are combined in one cable, significantly reducing material costs and installation labour compared to running separate power and control cables.

Product Features

• Hybrid Cross-Section Integrated Design:A single cable simultaneously contains 3×95mm² main power conductors, a 70mm² neutral conductor, and 3×6mm² auxiliary control conductors, replacing two separate cables and saving approximately 30–40% in installation space and material costs.
• XLPE Insulation with 90°C Temperature Resistance:Cross-linked polyethylene insulation allows the conductor to operate at a long-term temperature of 90°C, increasing current carrying capacity by 20–30% compared to PVC insulation (70°C), and providing a short-circuit withstand temperature of 250°C (5 seconds).
• Steel Tape Armor (STA) Double Protection:Double-layer galvanized steel tape wrapping provides pressure resistance, impact resistance, and rodent protection, allowing for direct underground burial without additional conduit.
• Low Loss Copper Conductor:All conductors are made of annealed copper (IEC 60228 Class 2), resulting in low DC resistance (95mm² ≤0.193Ω/km), high transmission efficiency, and low voltage drop.Flame-retardant PVC outer sheath: Black ST2 type PVC sheath, passing the IEC 60332-1-2 single-strand vertical burning test, and with added carbon black for UV resistance, suitable for outdoor cable tray installation.
• Wide temperature range adaptability: Fixed installation ambient temperature -15°C to +70°C, laying temperature not lower than 0°C (preheating is required below 0°C), suitable for projects in most climatic conditions.

Application Areas

YJV 0.6/1kV steel-tape armored hybrid cross-section cable is mainly used in fixed installation scenarios requiring the transmission of main power and control signals within the same cable:

Industrial Plants: Power supply to the motor control center (MCC). A 95mm² main core carries equipment signals, and a 6mm² auxiliary core transmits start/stop signals, eliminating the need for separate control cables.

Pump Stations and Water Treatment: Submersible pump main power supply + pressure/level sensor signals; integrated wiring reduces potential failure points.

Tunnels and Subways: Lighting distribution + ventilation/emergency control signals; steel-tape armored for pressure and impact resistance, suitable for underground environments.

Building Electrical Shafts: Incoming lines to floor distribution boxes (three-phase + neutral); auxiliary cores for fire alarm linkage or building automation, saving shaft space.

Ground-mounted Photovoltaic Power Stations: AC collector lines from inverter to transformer substation; armored for rodent and rock protection; auxiliary cores transmit inverter status signals.

Temporary construction power supply: from the main distribution box to the tower crane and pump truck, armored to withstand vehicle crushing and impacts, and auxiliary core connected to the emergency stop button to ensure safety.

FAQ

Q1: What's the difference between YJV and YJV22?

YJV is unarmored, while YJV22 is steel-tape armored. This product is actually YJV22 (with steel-tape armor) and can be directly buried.

Q2: Why does a single cable contain both 95mm² and 6mm² cores?

This is a mixed cross-section design. The 95mm² cores are used for main power transmission, and the 6mm² cores are used for auxiliary control (such as start/stop signals and sensors), providing dual functionality and eliminating the need for a separate control cable.

Q3: Which is better, steel-tape armored (STA) or steel-wire armored (SWA)?

STA is more resistant to pressure and rodents, suitable for direct burial; SWA is stronger in tensile strength, suitable for vertical or long-distance traction. For this product, STA is sufficient for most construction sites, tunnels, and direct burial.

Q4: Is additional conduit required for burial?

No. The steel tape armor itself provides mechanical protection; for direct burial, simply dig a trench, lay sand, lay the cable, lay more sand, and cover with warning tape.

Q5: What is the minimum bending radius?

Fixed installation: 12 times the cable outer diameter; Traction laying: 15 times the outer diameter (e.g., outer diameter 50mm, fixed bending radius ≥600mm).

Q6: Is the outer sheath UV resistant? Can it be installed outdoors?

Yes. The black PVC sheath is coated with carbon black, providing UV resistance, suitable for outdoor cable trays or surface installation.
