Description of 110kV Transmission Transformer

A 110kV Transmission Transformer is a medium-to-high voltage power transformer designed for regional electricity transmission and distribution networks. It serves as a critical link between high-voltage transmission grids (e.g., 220kV/500kV) and local distribution systems, stepping down voltage from 110kV to lower levels (typically 10kV/35kV) for industrial, commercial, and residential use. Widely deployed in substations, industrial parks, and urban/rural areas, it ensures stable power supply, reduces transmission losses over medium distances, and supports reliable grid operation.

Features of 110kV Transmission Transformer

• Optimal Voltage Level: Balances transmission efficiency and infrastructure cost, making it ideal for medium-distance power delivery (up to 100km) while minimizing voltage drop and energy loss.

• High Efficiency & Low Loss: Adopts advanced materials (e.g., amorphous alloy cores, low-resistance copper windings) to reduce no-load and load losses, meeting or exceeding international standards (e.g., IE3 efficiency class).

• Robust Construction: Designed to withstand environmental stresses (e.g., temperature variations, humidity, pollution) with sealed tanks, corrosion-resistant coatings, and moisture-proof insulation systems.

• Flexible Configuration: Available in various types (e.g., oil-immersed, dry-type), with options for on-load or off-circuit tap changers to regulate output voltage under fluctuating loads.

• Safety & Reliability: Equipped with protective devices (e.g., overcurrent/overvoltage relays, temperature sensors) and fail-safe mechanisms to prevent malfunctions and ensure continuous operation.

• Compact Design: Space-efficient footprint for easy installation in urban substations or confined spaces, often featuring noise-reducing enclosures to meet environmental regulations.

• Smart Grid Compatibility: Integrated with IoT sensors for real-time monitoring of temperature, oil quality, and partial discharges, enabling predictive maintenance and remote diagnostics.
