FAQ
1. What are the key technical specifications of your 110kV XLPE insulated cable?
Core Technical Standards:
Our YJLW02 / YJLW03 series high voltage cable is engineered for 110kV grid transmission. It features a high-purity copper or aluminum conductor, insulated with triple-extruded, super-clean Cross-linked Polyethylene (XLPE). Operating at a continuous conductor temperature of 90°C (and up to 250°C during short-circuit conditions), it fully complies with IEC 60840 and GB/T 11017 international standards, guaranteeing stable, high-capacity power transmission.
2. Why does this 110kV high voltage cable utilize a corrugated aluminum sheath?
Mechanical & Waterproof Protection:
High-voltage underground systems demand absolute protection. Our cable employs a continuously welded, corrugated aluminum sheath (indicated by ‘W’ in nomenclature). This design provides a 100% radial moisture barrier to prevent water treeing in the XLPE layer, exhibits excellent short-circuit current carrying capacity, and offers superior mechanical protection against soil pressure while maintaining optimal bending flexibility during installation.
3. How does ZHONGYI CABLE guarantee zero defects in 110kV XLPE insulation?
Advanced Quality Assurance & Partial Discharge Testing:
To prevent electrical breakdown, our 110kV cables are manufactured using a world-class VCV (Vertical Continuous Vulcanization) triple-extrusion line in a Class 100 cleanroom. Every single drum undergoes mandatory routine factory testing, including high-voltage AC resonance tests and Partial Discharge (PD) testing. We strictly guarantee a PD level of ≤ 5 pC (pico-coulombs), far exceeding standard safety requirements.
4. Can this high-voltage cable be customized with specialized outer jackets?
B2B Customization & Environmental Adaptability:
Yes. While our standard YJLW02 features a heavy-duty PVC outer sheath, we offer custom modifications to suit diverse burial environments. For superior abrasion resistance and low-temperature durability, we provide HDPE (YJLW03) jackets. Additionally, we can integrate a conductive graphite layer for post-installation sheath testing, anti-termite/anti-rodent additives, and Flame Retardant (FR-PVC) formulas for tunnel installations.
5. What are the standard packing lengths and logistics requirements for 110kV cables?
Heavy-Duty Engineering Logistics:
Due to the significant weight and bending radius of 110kV cables, they are packed on specialized, extra-large steel drums, with delivery lengths calculated precisely based on your site’s section-by-section trench layout to minimize intermediate joints. Every shipment includes Type Test Reports, routine test certificates, and specialized transport brackets. Our technical team also provides guidance on high-voltage cable terminations, joints, and cross-bonding grounding design.
