The high-voltage side voltage rating can range from 6kV to 35kV. High-voltage switches can be selected based on requirements, including oil-immersed load switches (suitable for distribution transformers), vacuum load switch-fuse combinations, or vacuum circuit breakers. When the project's altitude exceeds 3500 meters, it is generally recommended to opt for SF6 fully insulated ring main units to ensure the safe and reliable operation of the transformer.
Transformer options include units from American Transformer, Chinese Transformer, or dry-type transformers. Currently, ESVB-CUs with transformer capacities of up to 6300kVA are available, and larger capacities can be customized to meet specific customer demands.
Communication protocols for external communication can be customized to meet individual project requirements, as these can vary significantly from site to site. Common communication protocols include Modbus-RTU, Modbus-TCP, CAN2.0B, IEC61850, IEC60870-5-104, and IEC60870-5-103.
Each PCS (Power Conversion System) manufacturer has unique interface locations and types, necessitating the design of a tailored structure for each PCS manufacturer.
The AC measurement voltage level for PCS can range from 0.315kV to 0.69kV. Typically, for PCS AC measurement voltages at or below 0.4kV, the corresponding DC side rated voltage does not exceed DC1000V, and such models are predominantly intended for indoor use. For PCS AC measurement voltages between 0.5kV and 0.69kV, the corresponding DC side rated voltage is generally DC1500V, and these models are designed for outdoor use, often achieving IP54 or higher protection levels.
The ESVB-CU enclosure can be either a container-type enclosure, often custom-sized and fully welded, which tends to be relatively expensive, or a standard assembly-type enclosure, offering cost savings. In most cases, the latter option is recommended for clients.
Currently, the energy storage market predominantly features large-scale projects on both the grid side and the generation side. Contract values for individual energy storage projects with ESVB-CUs can range from millions to tens or even hundreds of millions of dollars.
Our production base covers an area of more than 600 acres (40 hectares) with extensive facilities and a total construction area of 180,000 square meters. We have a professional team of more than 1,000 employees. We have advanced transformer production and testing equipment here to ensure that we provide customers with high-quality power transformer products.
We boast an array of cutting-edge equipment representing a high standard within the industry, including a complete set of shearing machines, fully automated winding machines, robot-operated stacking machines, the Hedrch Vacuum Casting Equipment, vacuum impregnation systems, air cushion transport vehicles, a fully enclosed production workshop with a cleanliness level of 100,000, 20-ton vertical winding machines, 10-ton horizontal winding machines, coal-oil gas phase drying equipment, and a 200-ton overhead crane. We adopt the latest technology and processes to ensure that our products comply with international standards and customer needs.
We have a strong production capacity of 30 million kVA power transformers per year. This means we can cater to all sizes and types of power transformer needs, from small applications to large energy projects. No matter what specifications our customers require, we deliver them on time and support them with high quality and reliability.
