ZR-YJV 8.7/15kV Medium Voltage XLPE Insulated Flame Retardant Power Cable

The ZR-YJV 8.7/15kV is a high-performance flame-retardant medium-voltage power cable, optimized for 15kV industrial and utility power distribution networks. This cable utilizes an advanced three-layer co-extruded XLPE insulation structure, with both inner and outer layers being semi-conductive shielding layers, combining stable dielectric properties, excellent heat resistance, and flame-retardant safety. Unlike armored cables, the ZR-YJV features a lightweight structure, flexible laying, and low installation costs, making it perfectly suited for indoor conduits, tunnels, cable trenches, and non-direct burial applications. Manufactured entirely in accordance with IEC international standards and global industry specifications, this cable effectively suppresses partial discharge, resists insulation aging and water treeing, providing long-term stable operation for medium-voltage power transmission and meeting the stringent requirements of global engineering contractors, electrical engineers, and bulk purchasers for safety, durability, and system compatibility.

Core Technological Advantages of the Product

• Superior Electrical Stability: High-purity cross-linked polyethylene (XLPE) insulation effectively reduces partial discharge and dielectric loss, avoids electric field concentration, significantly delays insulation aging, and is suitable for long-term continuous load operation of medium-voltage systems, reducing the potential risk of line breakdown.
• Optimized Flame Retardant Safety: Special flame-retardant formulation materials limit the spread of flames in the event of a fire, preventing the fire from spreading along the circuit and improving the overall fire resistance rating of the system, meeting the fire safety design standards for public and industrial buildings.
• Lightweight Design, Convenient Construction: The unarmored streamlined structure reduces the overall weight and outer diameter of the cable, reducing laying difficulty, saving pipeline space, shortening the construction period, and effectively controlling the overall project laying cost.
• Strong Environmental Adaptability: The aging-resistant and chemical-corrosion-resistant outer sheath can withstand daily temperature variations, humidity, and mild chemical corrosion, making it suitable for complex indoor and semi-outdoor working environments with a service life of over 30 years.
• Low Operating and Maintenance Costs: The stable material performance and low failure rate require no routine maintenance, helping end-users worldwide reduce long-term operating costs and improve power supply system stability.

Key Considerations for Engineers and Procurement Personnel

• System Compatibility: The 8.7/15kV rated voltage design is specifically for 15kV medium-voltage power systems; please confirm the system grounding method and load current to select the appropriate conductor cross-sectional area.
• Installation Restrictions: This unarmored cable is not suitable for direct burial, areas subject to heavy pressure, impact, or frequent rodent activity; for harsh mechanical environments, please select the ZR-YJV22 armored version.
• Environmental Controls: Avoid prolonged exposure to strong UV radiation and severe chemical corrosion; protective conduit is recommended for outdoor exposed installation.
• Customization Support: A variety of flame retardant ratings, conductor specifications, and sheath materials are available to meet regional project bidding and local certification requirements.
