Description of 110kV Transmission Transformer

As a pioneer in China's power transformer industry, we have specialized in the R&D and manufacturing of power transformer equipment for decades, and established industry standards with core technologies.

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.

The voltage classes of some of these Power Transformer include  110kV 115kV 123kV 125kV 126kV 132kV 138kV 145kV 150kV 154kV 161kV 170kV  220kV 225kV 230kV 245kV 275kV 330kV 345kV 363kV 380kV 400kV 500kV Power transformers of voltage ,and aboveand customization is available.

This power transformer is fully compliant with international standards including IEC 60076-1, IEEE C57.12.00, ANSI C57.12.90, AS/NZS 60076.5 and EN 61558-1. It meets quality requirements and is widely adaptable to the operational needs of power grids in multiple overseas regions.

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.
