YJV 8.7/15kV MV Power Cable for Industrial & Utility Distribution

The YJV 8.7/15kV is a high-quality unarmored medium-voltage power cable designed specifically for 15kV grid operation, widely chosen by electrical engineers, EPC contractors, and industrial procurement teams worldwide. This cable features a three-layer co-extruded semi-conductive shield and high-performance XLPE insulation, achieving uniform electric field distribution, ultra-low partial discharge performance, and excellent resistance to water tree degradation and thermal aging.

Without steel tape armor, the cable's lightweight, streamlined structure optimizes laying efficiency and reduces overall project installation costs. Suitable for protected indoor and outdoor installation environments, it protects against severe mechanical shock, crushing, or rodent damage, ensuring continuous, safe, and stable power transmission in medium-voltage systems. Manufactured entirely according to IEC international standards and major global industry standards, this cable prioritizes long-term operational reliability, electrical safety, and cross-regional compatibility, making it an ideal choice for standardized commercial, industrial, and renewable energy projects globally.

Structure Type:

Unarmored, lightweight and compact design

Designed specifically for protective installation environments in global medium-voltage power systems:

• Indoor cable trenches, dedicated conduits, tunnels, and building internal power distribution
• Main power feeders for industrial plants, manufacturing facilities, chemical industrial parks, and factories
• Substation auxiliary circuits, medium-voltage switchgear connections, and power transition lines
• Commercial complexes, public infrastructure, hospitals, and educational facilities
• Renewable energy projects, including solar power plants, wind power plants, and energy storage-supported grids
• Urban municipal power grids with protective conduit installations and no risk of external mechanical damage

• Superior Dielectric Properties: The high-density cross-linked polyethylene (XLPE) insulation layer suppresses partial discharge and electric field distortion, effectively delaying insulation aging and extending service life. Stable electrical performance minimizes the risk of line faults under long-term variable load operation.
• Lightweight and Cost-Effective Installation: The unarmored design reduces cable weight and outer diameter, saving conduit space, reducing labor and laying costs, and shortening the construction cycle of large EPC projects.
• Excellent Thermal and Environmental Stability: Excellent heat resistance gives it a higher current-carrying capacity than conventional insulated cables. The robust outer sheath resists moisture, temperature fluctuations, and minor chemical corrosion, making it suitable for long-term outdoor protection environments.
• Simplified Engineering Matching: The compact structure supports flexible bending and complex wiring, perfectly matching globally standardized 15kV system designs and universal cable accessories, facilitating field termination and connection.
• Low Maintenance Costs: Highly stable material composition and advanced extrusion production technology significantly reduce daily maintenance needs, lowering long-term operation and management costs for power users.

• Application Restrictions: This unarmored YJV cable is prohibited from direct burial, unprotected underground trench laying, or locations frequently subjected to impact, compression, and rodent erosion. For harsh mechanical working environments, please select the YJV22 armored cable.
• System Parameter Matching: The 8.7/15kV rated voltage is suitable for standard 15kV grounded power systems. Engineers should confirm the system voltage level, grounding method, and actual load current to select the appropriate conductor cross-sectional area.
• Environmental Restrictions: Avoid prolonged exposure to direct ultraviolet radiation and highly corrosive gases; when laid outdoors in open conditions, protective conduits should be installed to prevent sheath aging.
• Customization Flexibility: Customized conductor sizes, core configurations, and special sheath materials are available based on regional building codes, tender requirements, and local certification requirements.

• Global Compliance: All products undergo third-party testing and hold CE, RoHS, and other relevant international certifications. We provide complete factory documentation, test reports, and certification materials to meet the needs of global project bidding, customs clearance, and project acceptance.
• Strict Quality Control: We use high-purity copper raw materials and premium XLPE compounds. Fully automated production, coupled with 100% online high-voltage withstand voltage, partial discharge, and resistance testing, ensures consistent batch quality.
• B2B Customized Solutions: We support non-standard specification customization, custom printing, and flexible minimum order quantities, serving bulk wholesale, long-term framework partnerships, and international EPC project orders.
• Factory Direct Sales: No middlemen, affordable prices, and stable production capacity. Standard export-grade wooden barrel packaging ensures safe long-distance sea and land transport.
• Professional Global Technical Support: Our professional engineering team provides cable selection guidance, installation advice, and parameter verification, promptly resolving technical challenges for international buyers, electrical engineers, and project contractors.
