What Is a 100 kVA Dry Type Transformer?

A 100 kVA dry type transformer is a vital component in today’s power distribution networks, known for its safety, efficiency, and ease of maintenance. Unlike traditional oil-immersed transformers, this type uses air or solid insulation materials instead of oil, which significantly reduces the risk of fire and eliminates environmental concerns related to oil leaks or spills. SYHF’s 100 kVA dry type transformer is built with cutting-edge technology and premium components, ensuring a long operating life and stable performance even in demanding conditions. In 2024, this transformer was successfully delivered to South Africa, where it has been integrated into local power systems to support reliable electricity distribution.

This transformer features a fully sealed structure without an oil storage cabinet, meaning the transformer oil is completely isolated from exposure to air and sunlight. This design helps prevent oil oxidation and moisture absorption, which are key contributors to insulation aging. As a result, the transformer maintains higher insulation quality over time, extending its service life and reducing the need for repairs or replacement. SYHF’s model is designed with efficiency in mind, offering low energy loss during operation, which not only conserves power but also reduces operating costs for users.

In terms of safety and environmental protection, the transformer is both fireproof and explosion-proof, making it suitable for use in densely populated or high-load areas such as commercial centers, medical facilities, and industrial complexes. The absence of oil also means there is no need for regular oil maintenance, resulting in a virtually maintenance-free operation that minimizes long-term service expenses. To suit various installation environments, the outer shell of the transformer can be made from stainless steel or aluminum cold plates and is available with multiple cooling designs such as top air outlet, hot air type, or bottom air inlet.

Furthermore, the transformer can be customized with an integrated temperature control system. This feature allows real-time temperature monitoring and data display, giving users better insight into the unit’s thermal conditions and allowing proactive maintenance decisions. With all these features combined, SYHF’s 100 kVA dry type transformer offers a future-ready, safe, and economical solution for power distribution projects seeking high reliability and long-term performance.
