220kv Power Transformer

The 220kV power transformer is a critical component in high-voltage transmission and substation systems. It is designed to operate reliably at voltage levels of 220kV and 230kV, enabling efficient power transfer between transmission networks and regional grids. These transformers are widely applied in national power grids, utility substations, and large-scale industrial energy systems.

A 230kV/220kV power transformer performs precise voltage conversion to meet different grid requirements. It can function as either a step-up transformer for long-distance power transmission or a step-down transformer for stable and safe power distribution.

Voltage Rating and Operating Capability

This transformer features a high-voltage side rated at 230,000 volts and a low-voltage side rated at 220,000 volts. Its design ensures stable electrical performance under high electrical stress, temperature fluctuations, and continuous operation conditions commonly found in high-voltage substations.

Step-Up and Step-Down Functionality

The ability to step up or step down voltage makes the 220kV power transformer an essential element of modern power systems. Stepping up voltage reduces transmission losses over long distances, while stepping down voltage allows safe integration with downstream distribution networks.

Three-Phase Transformer Design

The transformer is designed for three-phase operation, ensuring balanced load distribution and high transmission efficiency. Three-phase construction enhances system stability, reduces energy losses, and supports reliable grid operation in high-capacity power networks.

High-Voltage Safety and Reliability

Operating at 220kV requires strict compliance with safety and performance standards. The transformer incorporates advanced insulation systems, robust winding structures, and effective cooling solutions to prevent electrical breakdown and thermal stress, ensuring long service life and reliable operation.

Typical Models

Common models include SFSZ20-240000/220 and SZ18-130000/220, suitable for high-capacity substations and transmission projects requiring stable voltage conversion at the 220kV level.

Quality Standards and Certifications

All 220kV power transformers are manufactured under a quality management system compliant with GB/T 19001-2016 and ISO 9001:2015. The entire production process, from design and material selection to testing and delivery, is strictly controlled.

The products comply with international standards, including IEC 60076, and have obtained UL, CUL, and CE certifications. Each transformer undergoes comprehensive factory testing to ensure consistent quality and dependable performance.

Applications

The 220kV power transformer is widely used in high-voltage substations, regional and national power grids, industrial power systems, and large-scale infrastructure and energy projects.

With high efficiency, robust construction, and international certification, the 220kV power transformer provides a reliable solution for modern high-voltage power transmission and substation applications.
