YJLV22 8.7/15kV Medium Voltage Cable Industrial & Municipal Grid

The YJLV22 8.7/15kV is an economical and efficient aluminum-core medium-voltage armored power cable, tailored for global EPC contractors, power engineers, and large infrastructure purchasers. It features a compact aluminum conductor, three layers of co-extruded XLPE insulation, double-layer semi-conductive shielding, steel tape armor, and a durable PVC outer sheath.

Optimized for 15kV nominal distribution systems, this cable combines excellent dielectric stability, resistance to mechanical shock, compressive strength, and outdoor environmental adaptability. Compared to copper-core medium-voltage cables, the YJLV22 offers significant cost advantages and lighter weight while maintaining adequate partial discharge control, thermal aging resistance, and long-term operational safety. The STA armor construction effectively addresses the risks of mechanical damage, crushing, and rodent intrusion, making it suitable for direct burial and harsh outdoor installation environments. Manufactured entirely according to IEC and international industry standards, this product ensures high compatibility with global medium-voltage power systems, regional building codes, and mainstream cable accessories.

High-quality aluminum conductors significantly reduce the total material cost and cable weight of projects, thereby reducing transportation, handling, and installation labor costs, making it an ideal choice for large-scale, long-distance power transmission.

Integrated shielding and high-purity cross-linked polyethylene (XLPE) insulation ensure uniform electric field distribution, effectively suppressing partial discharge and insulation degradation, and adapting to long-term fluctuating loads and harsh outdoor temperatures.

Double-layer steel tape armor provides strong resistance to compression, impact, and bite, fully adapting to direct burial trenches, backfilling compression, and complex construction site conditions, significantly reducing the failure rate due to external damage.

The weather-resistant outer sheath resists UV corrosion, damp soil, and weak acid and alkali corrosion, maintaining stable performance in high-temperature, high-humidity, and seasonal extreme climates, extending the overall cable life.

Unified industry-standard sizes and interfaces are compatible with mainstream global medium-voltage cable connectors, terminals, and auxiliary accessories, facilitating on-site cutting, wiring, and rapid construction delivery.

Aluminum conductors are lighter and less expensive; engineers need to appropriately increase the cross-sectional area based on current requirements to compensate for their slightly different conductivity compared to copper core cables.

Built-in steel tape armor is designed for direct burial, underground conduit, and heavy-duty industrial applications; it is preferred for outdoor buried projects without additional protective conduits.

The steel tape armor and copper shielding must be reliably grounded in the field to ensure fault current discharge and prevent induced voltage interference.

Customized sheath formulations and standard upgrades are supported to meet local power industry regulations in Europe, Africa, Southeast Asia, and other regions, ensuring successful project acceptance.

We possess complete CE, RoHS, and quality system certifications, providing full sets of third-party test reports and factory qualification documents to support international bidding, customs clearance, and cross-border project approvals.

We use high-purity aluminum rods, branded XLPE insulation materials, and high-strength steel strips. Fully automated closed-loop production, 100% offline high-voltage testing, and partial discharge detection ensure consistent batch quality.

We support customized cross-sections, core wire structures, special UV-resistant sheaths, and printing content. Flexible minimum order quantities and stable bulk delivery cycles meet the needs of EPC projects, wholesalers, and long-term cooperative buyers.

Direct factory supply eliminates middleman markups, resulting in significantly better value for large-volume medium-voltage engineering orders and helping buyers effectively control project budgets.

We provide free cable current carrying capacity calculations, cable selection advice, installation specification guidance, and after-sales technical support, promptly resolving professional wiring issues for our global electrical team.
