Jiangsu Yawei Transformer Co., Ltd.

30 kva dry type transformer

A 30kVA dry-type transformer is a medium-sized electrical transformer with a rated capacity of 30 kilovolt-amperes (kVA) that operates without the use of traditional transformer oil for cooling and insulation. Instead, it relies on solid or cast resin as the dielectric material for insulation and uses air for cooling.

 

Product Introduction

 

Dry-Type Design: Unlike traditional oil-immersed transformers, dry-type transformers do not require oil as a cooling and insulating medium. Instead, they use solid or cast resin insulation and air for cooling. This design eliminates the risk of oil leaks, making them suitable for indoor installations.

 

Applications: Dry-type transformers of this size are commonly used in various applications, including commercial and industrial buildings, schools, hospitals, data centers, and other places where safety, environmental, or space considerations make oil-immersed transformers less practical.

 

Efficiency: Dry-type transformers are known for their high efficiency and minimal energy loss. They are designed to meet strict energy efficiency standards, making them environmentally friendly and cost-effective over the long term.

 

30kVA dry-type transformer is a versatile and efficient electrical transformer designed for various indoor applications. Its dry-type design, high efficiency, and minimal maintenance requirements make it a suitable choice for powering medium-sized loads in commercial and industrial settings, where safety, space, and environmental considerations are important factors.
