Description

YJLHV22 (8.7/15kV) is a medium-voltage (MV) power cable designed specifically for 10kV distribution networks. It features 8000 series aluminum alloy conductors, cross-linked polyethylene (XLPE) insulation, copper tape shielding, galvanized steel tape armor, and a low-smoke halogen-free (LSZH) outer sheath. Rated at 8.7/15kV (Um=17.5kV), it is designed for applications such as urban power grids, industrial parks, critical public utilities, and renewable energy projects, offering high safety, mechanical protection, fire resistance, and cost-effectiveness.

Compared to traditional copper-core YJV22 or aluminum-core YJLV22 cables, YJLHV22 (8.7/15kV) offers advantages such as lighter weight, superior fire/smoke resistance, robust armor, and stable electrical performance, making it the preferred choice for engineers and procurement personnel in high-reliability, fire-resistant, and budget-sensitive medium-voltage projects.

5. Engineering and Procurement Key Points
5.1 Design and Selection Guidelines
  • Voltage Matching: Strictly applicable to 10kV (8.7/15kV) systems; not permitted for higher voltage levels.
  • Cross-section Selection: Calculated based on load current, voltage drop, and short-circuit capacity; a 20% derating should be considered for direct burial in high-temperature soil.
  • Fireproof Areas: Mandatory use of Low Smoke Halogen-Free (LSZH) + Class A flame-retardant materials (e.g., hospitals, subways, data centers).
  • Harsh Environments: For coastal/chemical areas, reinforced LSZH sheathing + corrosion-resistant armor coating should be specified.
5.2 Installation and Laying Specifications
  • Temperature Control: Not permitted for laying below 0°C; avoid impact/bending in cold weather.
  • Bending Radius: The bending radius of a 3-core cable should be 15 times its outer diameter; sharp bends or kinks are prohibited.
  • Tensive Force: Maximum tensile force ≤ Avoid overstretching when pulling cables with a cross-sectional area of ​​3 N/mm².
  • Direct burial: Lay a 100 mm layer of fine sand under/above the cable; cover with concrete slabs or bricks to prevent damage from sharp objects.
  • Termination and joints: Use aluminum alloy compatible terminals; install by qualified personnel to avoid overheating at connections.
  • Grounding: Both ends of the metal shielding and armor must be reliably grounded according to IEC 60287 standards.
3. Procurement and Acceptance Checklist
  • Documents: Verify type test report, factory test report, flame retardant/smoke/halogen test report, and Certificate of Conformity (COC)
  • Visual Inspection: Inspect the sheath for cracks, dents, or damage; confirm that markings are clear and continuous (dimensions, voltage, standards)
  • Sampling Testing: For bulk orders, perform partial discharge, dielectric strength, and sheath resistance tests according to GB/T 12706 standard.
  • Storage: Store in a dry, well-ventilated warehouse; avoid prolonged exposure to outdoor environments; store in reels, do not stack flat.
Practical Application Cases
