‌High Voltage Transformer‌ A high-voltage transformer steps up/down voltage (typically 11 kV–765 kV) for efficient power transmission and distribution. Comprising laminated silicon steel cores, copper/aluminum windings, and oil/air/gas insulation, it minimizes energy loss and heat generation. Key applications include grid substations, industrial plants, and renewable energy integration (wind/solar farms). Features include Buchholz relays, temperature monitors, and pressure relief devices for fault protection. Compliant with IEC 60076 or GB 1094 standards, modern designs use amorphous alloy cores for higher efficiency (up to 99.7%) and smart sensors for real-time monitoring of load, oil quality, and partial discharge. Weatherproof enclosures (IP55), anti-vibration mounts, and flame-retardant materials ensure reliability in harsh environments. Compact, eco-friendly (SF₆-free), and noise-optimized, it enhances grid stability, reduces transmission losses, and supports renewable energy scalability.
