YJV 26/35KV 1*300 Cross-linked polyethylene Insulated Power Cable

Overview

The YJV 26/35kV 1x300 is a high-performance single-core medium voltage power cable engineered for the most demanding high-capacity electrical transmission networks. Designed with a premium 300mm² Class 2 stranded copper conductor and highly durable cross-linked polyethylene (XLPE) insulation, this cable guarantees exceptional conductivity, minimal energy loss, and outstanding long-term thermal stability. It serves as the ultimate backbone for modern urban power grids, large-scale industrial parks, and advanced renewable energy infrastructures where reliability is non-negotiable. Core Features and Engineering Advantages High-Purity Copper Conductor: The 300mm² compacted copper core ensures maximum current-carrying capacity, significantly reducing electrical resistance and minimizing power dissipation across long-distance transmissions. Advanced XLPE Insulation: The cross-linked polyethylene insulation allows the cable to operate continuously at a maximum temperature of 90°C and withstand transient short-circuit temperatures up to 250°C for up to 5 seconds. This robust thermal endurance handles heavy, fluctuating power loads effortlessly. Triple Extrusion Technology: Manufactured with seamlessly extruded semi-conducting layers for both conductor and insulation shielding, the cable maintains a perfectly uniform electrical field. This precise construction guarantees excellent partial discharge performance, consistently testing below 10 pC at 1.5 U0. Durable PVC Outer Sheath: The resilient polyvinyl chloride (PVC) jacket provides superior protection against moisture ingress, mild chemicals, and environmental degradation, ensuring a prolonged operational lifespan in challenging subterranean installations. Strict Technical Compliance Quality and safety are built into every meter of the YJV 26/35kV 1x300 power cable. It is manufactured and rigorously tested in strict compliance with international IEC 60502-2 and domestic GB/T 12706.3 standards. Before leaving the facility, each batch passes an extreme power frequency withstand voltage test—enduring 65kV for 30 minutes without breakdown—to guarantee field-ready reliability and grid security. Investing in robust medium voltage infrastructure is critical for operational safety and long-term efficiency.
