10kV Cast Resin Dry-Type Transformer Price & Selection Guide (30–4000kVA)
Time：2025-12-16 Auther：ZTelec-www.ztelectransformer.com
The price of a 10kV cast resin dry-type transformer is influenced by multiple technical and project-related factors rather than a single fixed value. This guide explains how transformer pricing is determined, how to select the correct model, and how to achieve the best balance between initial investment and long-term operating cost for projects ranging from 30kVA to 4000kVA.
What Affects the Price of a 10kV Cast Resin Dry-Type Transformer
Transformer capacity is one of the primary cost drivers. As rated capacity increases from 30kVA to 4000kVA, material consumption, core size, winding volume, and cooling system requirements increase accordingly, resulting in higher manufacturing costs.
Energy efficiency level has a significant impact on price. High-efficiency cast resin dry-type transformers use low-loss magnetic core materials and optimized winding designs, which reduce no-load loss and load loss. While the initial price may be higher, long-term electricity savings often outweigh the upfront cost difference.
Insulation class and temperature rise also influence pricing. Transformers designed with Class F or Class H insulation materials offer improved thermal performance and longer service life, especially in high-temperature or high-load environments.
Enclosure protection level is another factor. Standard indoor models with IP20 protection are more economical, while customized IP23 or higher protection ratings for semi-outdoor or harsh environments will increase manufacturing cost.
Additional configurations such as forced air cooling, intelligent temperature control systems, remote monitoring interfaces, and special standards compliance can also affect the final transformer price.
Typical Price Range Reference
For general reference, small-capacity 10kV cast resin dry-type transformers in the 30–100kVA range are typically used for local distribution and auxiliary power systems. Medium-capacity models from 160kVA to 1000kVA are common in commercial buildings and industrial facilities. Large-capacity transformers from 1250kVA to 4000kVA are mainly applied in infrastructure projects, data centers, and renewable energy systems.
Due to variations in configuration, standards, and project requirements, exact pricing should always be confirmed through technical evaluation and quotation. A detailed specification will help ensure accurate cost estimation.
How to Select the Right 10kV Cast Resin Dry-Type Transformer
Capacity selection should be based on accurate load calculations, considering both current demand and future expansion. Reserving a reasonable safety margin helps prevent overloading and improves long-term reliability.
Energy efficiency class should be selected according to project goals. For projects with long operating hours or high electricity costs, high-efficiency models provide better lifecycle value despite a higher initial investment.
Installation environment plays a critical role in model selection. Indoor installations typically require IP20 protection, while outdoor or semi-outdoor locations benefit from IP23 or higher protection levels. Ambient temperature, humidity, dust, and ventilation conditions should also be considered.
Cooling method selection depends on capacity and installation space. Natural air cooling is sufficient for most standard applications, while forced air cooling is recommended for higher capacities or limited space environments.
Cast Resin Dry-Type Transformer vs Oil-Immersed Transformer Cost
Compared with oil-immersed transformers, cast resin dry-type transformers generally have a higher initial purchase price. However, they offer lower installation and maintenance costs due to their oil-free structure, reduced fire protection requirements, and minimal routine maintenance.
Over the full lifecycle of the equipment, cast resin dry-type transformers often provide better overall economic performance, especially in indoor installations and fire-sensitive environments.
Applicable Standards and Quality Assurance
High-quality 10kV cast resin dry-type transformers are manufactured in accordance with IEC, ANSI, and GB standards. Routine tests and type tests are conducted to verify electrical performance, insulation strength, temperature rise, and safety before delivery.
Compliance with recognized international standards ensures stable operation, easier project approval, and long-term reliability.
