Product Introduction
Overview
• 52kV and below power transformers provide reliable voltage transformation between transmission and distribution levels, engineered for high efficiency, low losses and robust insulation performance. Flexible configurations, cooling methods and monitoring options support utility, industrial and renewable projects with grid integration.
Application
• 52kV and below power transformers serve substations, industrial plants and renewable interconnections, stepping voltage between medium-voltage feeders and transmission lines. They enable reliable load growth and network reconfiguration, supporting flexible operating modes, on-load tap control and protection schemes aligned with regional standards.
Advantages
• 52kV and below power transformers offer optimized loss performance, robust short-circuit withstand and precise voltage regulation, reducing lifecycle ownership costs. Standardized designs simplify engineering, streamline maintenance and enhance fleet interchangeability while supporting digital monitoring for grid operators and asset management.
Feature
• The 52kV and below power transformer, the use of company- specific calculation and verification procedures, the transformer core, coils, active part, leading tanks and other components for a full range of optimized design and verification, to ensure product performance. Superior technology equipment, careful selection of materials, and efficient manufacturing make the transformer small, light weight, low loss, low PD, low noise and other characteristics of superior product quality, energy saving and environmental protection, reliable operation and effectively reduce the Product operating costs.
