35kV Class Epoxy-Resin Cast Dry-Type Transformer

Safe and Reliable: We use high-quality materials and advanced manufacturing processes. The high-voltage coil windings are arranged in a tower-like structure, allowing for optimal optimization of the coil’s magnetic field strength. In addition, the dry-type transformer is equipped with an online temperature measurement and monitoring system, effectively preventing equipment overheating and subsequent shutdowns. High Efficiency and Energy Saving: The transformer features high efficiency and low losses, significantly reducing energy waste and carbon emissions. It employs a self-developed fan start-stop logic that lowers operating temperatures, enhances heat dissipation efficiency, and minimizes energy loss. Energy- and Environment-Friendly: The transformer is made from energy- and environment-friendly materials that minimize environmental impacts throughout the manufacturing, use, and disposal phases, while also improving energy utilization efficiency. Simple Maintenance: The transformer requires only periodic checks to ensure that temperature readings remain within normal ranges. It has no easily worn components, and routine testing along with regular dust removal are sufficient—no component replacements are typically needed.

Detailed description

The 35kV epoxy-encapsulated dry-type transformer is one of our company’s core products, developed specifically for applications in new energy and scenarios with high environmental protection requirements. The product series includes models such as SCB11, SCB12, SCB13, SCB14, and SCB18. These transformers fully meet the Level 3, Level 2, and Level 1 energy efficiency requirements specified in GB 20052-2024 “Energy Efficiency Limit Values and Energy Efficiency Levels for Power Transformers,” striking a balance between energy-saving performance and operational reliability.

In terms of capacity coverage, products rated at 35 kV and below can achieve a maximum capacity of up to 25,000 kVA, effectively meeting the power demands of large-capacity new energy power stations and industrial loads. The high-voltage winding adopts a trapezoidal segmented structure design, which effectively reduces the inter-layer voltage and the electric field strength between segments, resulting in a more uniform electric field distribution and significantly enhancing the transformer's ability to withstand overvoltages and its insulation reliability. The entire winding is cast using a fully static pouring process with epoxy resin, ensuring dense casting, high mechanical strength, and excellent resistance to short circuits. The partial discharge level is lower than the values specified by national standards, and the transformer exhibits high long-term operational stability.

This product series features low power loss, low noise, and remarkable energy-saving performance. It is environmentally friendly, pollution-free, and boasts excellent fire-resistant properties, making it particularly suitable for application environments with high demands on safety, environmental protection, and operational reliability. It is primarily used in new energy sectors such as photovoltaic power generation, wind power generation, and energy storage systems. Additionally, it is well-suited for data centers, rail transit systems, public buildings, and other venues that have special requirements for fire resistance, environmental protection, or installation conditions, demonstrating broad adaptability across various applications.

Dry-Transform Energy Storage Integrated Unit—Container Structure

Dry-Transform Energy Storage Integrated Unit—Container Structure

Safe and Reliable: The packaged substations are equipped with comprehensive electrical protections against overload, short circuit, ground fault, and other electrical hazards. The transformers themselves feature non-electrical protections such as temperature, oil level, pressure, and gas monitoring. Moreover, the system can be monitored in real time from the background control center, and remote operations can be performed from there, ensuring the continuous safe operation of the equipment at all times. High Integration: The entire system is pre-manufactured and pre-commissioned at the factory. After integration and testing, it is delivered to the site as a complete unit. On-site, all that’s required is connecting the high- and low-voltage cables and control/communication cables to put the system into operation—thus significantly reducing on-site work and boosting construction efficiency. Energy-Efficient and Environmentally Friendly: The transformers are made from energy-saving and environmentally friendly materials, and their design has been optimized to minimize no-load losses and improve operational efficiency, meeting national energy-saving standards. An advanced cooling system is employed to lower operating temperatures, enhance heat dissipation efficiency, and reduce energy losses. Flexible Configuration: Whether it’s a photovoltaic power generation or wind power generation project, we can provide tailored packaged substation solutions. Based on the specific site conditions and project requirements, we’ll rationally configure the substation’s capacity, incoming and outgoing cable connections, protection levels, and other parameters to meet the unique needs of each site.
