| Full Name | Copper Conductor, XLPE Insulated, Corrugated Aluminum Sheathed, PVC Outer Sheathed High Voltage Power Cable | Copper Conductor, XLPE Insulated, Corrugated Aluminum Sheathed, PE Outer Sheathed High Voltage Power Cable |
| Conductor Material | Class 2 Compacted Stranded Copper (Excellent electrical conductivity & high current carrying capacity) | |
| Insulation & Shield | Cross-linked Polyethylene (XLPE) Insulation with 100% impermeable Corrugated Aluminum Sheath | |
| Outer Jacket Material | Polyvinyl Chloride (PVC) — Ideal for chemical resistance and standard layouts | Polyethylene (PE) — Harder, higher density, and provides better protection against structural wear |
| Direct Burial Ability | Not recommended for harsh direct burial due to standard moisture permeability over long-term water contact | Approved for Direct Burial (Superior waterproof performance, low water permeability, and high crush tolerance) |
| Flame Retardancy | Enhanced Safety (Inherent flame retardant properties, suitable for indoor cable tunnels and trenches) | Low flame retardancy (Requires additional fire-resistant coating or special additives if used indoors) |
| Operating Temperature | -15°C to +90°C (Standard environmental thermal margin) | -40°C to +90°C (Excellent low-temperature flexibility and thermal stress resistance) |
Superior Water Resistance: PE has a near-zero water absorption rate, preventing radial moisture ingress for long-term underground submersion.
High Voltage Reliability: Specially engineered for safe and stable power transmission from 66kV up to 500kV grids.
Excellent ESCR & Low-Temp Flexibility: Maintains physical integrity in temperatures ranging from -40°C to +90°C and resists Environmental Stress Cracking (ESCR).
Superior Moisture Proofing: Equipped with a corrugated aluminum sheath providing 100% radial water-blocking performance.
High Current Capacity: Features high-purity copper conductors with a maximum continuous operating temperature of 90°C.
Application
Urban Power Grids: Ideal for underground high-voltage power transmission networks in densely populated cities.

FAQ
1. What is the fundamental role of the corrugated aluminum sheath in YJLW02 high-voltage cable?
Core Shielding & Moisture Barrier:
The ‘W’ and ’02’ in the YJLW02 nomenclature designate a continuously welded, corrugated aluminum sheath protected by a heavy-duty PVC outer jacket. For 110kV high-voltage grids, this corrugated aluminum layer functions as a 100% impervious radial moisture barrier that prevents water treeing degradation within the XLPE insulation. Additionally, it offers exceptional mechanical crush resistance against underground soil pressure while maintaining mandatory bending flexibility during complex trench or tunnel routing.
2. How does ZHONGYI CABLE guarantee zero electrical defects in the 110kV XLPE insulation layer?
Advanced Quality Control & VCV Production:
To mitigate any risk of high-voltage dielectric breakdown, our YJLW02 cables are manufactured utilizing a world-class VCV (Vertical Continuous Vulcanization) triple-extrusion line operating in a Class 100 super-clean cleanroom environment. This guarantees perfect concentricity of the insulation layers. Furthermore, every single shipping drum undergoes mandatory high-voltage AC resonance testing and ultra-sensitive Partial Discharge (PD) testing to ensure an industry-leading PD level of ≤ 5 pC (pico-coulombs).
3. What continuous and short-circuit thermal limits can the YJLW02 cable safely withstand?
Thermal Thresholds & Grid Reliability:
Engineered for critical utility-scale bulk power transmission, our 110kV YJLW02 cable employs premium, super-clean Cross-linked Polyethylene (XLPE). It supports a continuous conductor operating temperature of 90°C under full load conditions. In the event of emergency grid faults or sudden short-circuits, the cable is rated to withstand severe thermal spikes up to 250°C for a maximum duration of 5 seconds without compromise to its structural integrity.
4. Can the outer PVC jacket of YJLW02 be customized for specialized grid environments?
B2B Material Engineering & Customization:
Yes. While our standard YJLW02 features a premium, robust PVC outer sheath ideal for standard installation, we provide tailored modifications to match specific engineering blueprints. We can integrate a conductive graphite coating on the exterior to facilitate precise post-installation outer sheath integrity testing. For specialized installations, we offer anti-termite/anti-rodent chemical additives, or flame-retardant (FR-PVC) compounds optimized for dedicated power cable tunnels.
5. What are the engineering logistics and delivery standards for 110kV high-voltage cable drums?
Heavy-Duty Project Logistics:
Given the substantial net weight and specific minimum bending radius of 110kV single-core cables, all YJLW02 shipments are delivered on specialized, heavy-duty steel or reinforced steel-wooden drums. Total segment lengths per drum are precisely calculated based on your engineering site layout to minimize the need for high-voltage intermediate straight joints. Every shipment includes comprehensive Type Test Reports, Routine Factory Certificates, and specialized secure transit packaging.
