Excellent Electrical & Thermal Performance：1. High Insulation Grade & Reliability: Utilizes super-clean XLPE insulation, specifically designed for voltage classes like 8.7/15kV and 26/35kV. Features extremely low partial discharge and can withstand high electrical stress long-term, ensuring safe power transmission.
2. Superior Heat Resistance & Current-Carrying Capacity: Long-term permissible conductor temperature up to 90°C, and up to 250°C under short-circuit conditions. Compared to LV cables, the design emphasizes higher ampacity and lower losses for improved transmission efficiency.
Strong Environmental Adaptability & Mechanical Protection：1. Robust Protective Construction: Steel tape armor (e.g., YJV22) provides anti-crush protection for direct burial. Steel wire armor (e.g., YJV32, YJV42) provides tensile strength for vertical installation, underwater routes, or large elevation differences.
2. Solves HV-Specific Issues: Non-magnetic armor (e.g., YJV62, YJV72) is specifically used for single-core HV cables to prevent eddy current losses that cause heating and energy waste.
3. Excellent Moisture & Weather Resistance: Metallic sheaths or HDPE outer sheaths offer
