35kV YJV22 XLPE Armored Cable 0.6/1kV Single Core Or Multi Core

YJV22 is a steel-tape armored low-voltage copper core power cable designed for fixed installation environments, suitable for applications where the cable must withstand higher mechanical stresses than standard cable tray wiring. It is commonly used in underground conduits, cable trenches, protective trenches, and building access lines, where cables must withstand backfill soil compression, line loads, and harsh traction conditions. YJV22 features XLPE insulation for stable electrical performance and a PVC outer sheath for improved surface durability, making it ideal for contractors and EPC purchasers seeking a reliable and convenient underground low-voltage power distribution solution.

Typical Rated Voltage: 0.6/1 kV

Applications: Low-voltage feeders and sub-feeders in fixed installations

Please confirm the reference standards and acceptance requirements listed in the Bill of Materials (BOQ).

• 1C for high-current feeders and phase-separated wiring
• 2C for dedicated single-phase circuits
• 3C for three-phase circuits without a neutral (Design-Specific)
• 4C for three-phase distribution with a neutral conductor
• 5C for three-phase distribution with a neutral conductor and protective earth (PE) conductor
• 3+1 and 3+2 are used in many common market feeder layouts

Availability depends on conductor grade, standard requirements, and reel length planning.

• Underground conduit and duct power distribution
• Conduit feeders in industrial parks and zones
• Protective trench wiring in commercial and industrial sites
• Incoming lines to main low-voltage switchboards in buildings
• Utility corridors and cable tunnels with external pressure risks
• Stationary power distribution lines designed for mechanical protection

• Conductor: Copper stranded wire
• Insulation: Cross-linked polyethylene (XLPE)
• Core Assembly: Stranded core wires with filler/adhesive added as needed
• Protective Layer: Protective protective layer
• Armor: Steel tape armor (STA)
• Outer Sheath: Polyvinyl chloride (PVC)
• Applications: Fixed installations, especially suitable for underground protection wiring

1. Conductor Preparation

   The drawing and stranding of the copper wire are strictly controlled to meet resistance targets and ensure the bending performance required for wiring installation.

2. Insulation Extrusion and Cross-linking

   The XLPE insulation layer is extruded and cross-linked to form a robust dielectric layer suitable for low-voltage distribution applications.

3. Core Wire Routing and Geometry Control

   The core wires are identified and stranded with a controlled geometry to maintain roundness and reduce pull-out friction.

4. Protective Layer Formation

   A protective layer is laid to protect the core wire bundle and provide a stable base for the steel tape armor.

5. Steel Strip Armor

   The steel strips are wound in a controlled overlapping manner to provide mechanical reinforcement, primarily resisting compression and external pressure.

6. PVC Sheath and Marking

   The PVC sheath is manufactured using an extrusion process and is used to protect the armored structure. It is then marked for traceability and project control.

7. Routine Inspections

   Typical inspections include conductor resistance, insulation thickness verification, spark testing, voltage testing, dimensional inspection, and sheath integrity checks.

1. Please confirm the reference standards and testing requirements in the bill of quantities. (BOQ)
2. Select core wire configuration based on the power distribution scheme and neutral/protective conductor design.
3. Select cross-sectional area based on load current, distance, grouping, ambient temperature, and allowable voltage drop.
4. Define wiring type and protection method (cable trench, conduit, protective trench, corridor).
5. Specify preferred reel length to reduce joints and speed up installation.
6. If the project requires flame retardant, low smoke halogen-free (LSZH), or fire-resistant properties, specify the required category to match the correct model.
