The 10–15kV open-type dry-type distribution transformer is a dry-type substation unit with an open, enclosure-free structure, cooled by two methods—natural air and forced air. Simple, lightweight, and economical to produce, it offers good heat dissipation, intuitive and convenient inspection, and stable, durable operation.
It is widely used in indoor distribution settings with good ventilation and no stringent fire-protection or enclosure requirements, such as factory workshops, industrial and mining sites, and equipment-room distribution areas.
Product Description
The 10–15kV open-type dry-type distribution transformer is an open dry-type distribution transformer with an exposed-coil structure, cooled by two methods—natural air and forced air. Suited to 10kV, 11kV, 13.8kV, and 15kV AC power systems, it transforms voltage levels and distributes power.
This product is built with a premium, high-permeability silicon-steel core and pure-copper windings, with no enclosed casing—giving it a simple, compact structure and flexible installation and placement. With excellent ventilation and heat dissipation, it offers low temperature rise and low operating losses, while making routine inspection, fault checking, and maintenance clear at a glance and highly convenient. The unit delivers strong overall value for money, rugged durability, and reliable insulation performance, along with strong overload capacity and low operating noise. Suited to well-ventilated indoor power-supply environments, it is widely used across industrial workshops, production sites, small and medium-sized factory buildings, equipment rooms, and other general indoor distribution applications.
This product complies with GB/T 1094 Power Transformers, GB/T 10228-2023 Specification and Technical Requirements for Dry-Type Power Transformers, GB 20052-2024 Permissible Values of Energy Efficiency and Energy Efficiency Grades for Power Transformers, and IEC 60076 Power Transformers.
This article focuses on transformer selection for solar power plants. Building on a previous general comparison of oil-immersed and dry-type transformers, it examines the specific requirements of photovoltaic applications. The article outlines product solutions for different scenarios—large ground-mounted plants, commercial rooftops, and building-integrated photovoltaics—covering oil-immersed transformers, dry-type transformers, specialized box-type transformers for renewable energy, box-type substations, and high/low voltage switchgear. It then analyzes key technical factors unique to solar projects, including harmonic mitigation, voltage fluctuation and bidirectional power flow, insulation coordination, outdoor environmental endurance, and total cost of ownership over a 20-plus-year operating cycle. Drawing on Dada Electric's manufacturing experience, this guide offers project developers and engineers a practical, application-focused selection reference. Read More
Choosing the right transformer is a critical techno-economic decision for any power project. This article provides a detailed comparison between oil-immersed and dry-type transformers, focusing on safety, installation environment, maintenance, reliability, and total life-cycle cost. By walking through four key questions—installation location, fire safety level, available maintenance resources, and full cost of ownership—project decision-makers can confidently select the optimal technology. With complete manufacturing lines for both transformer types, Dada Electric offers unbiased, application-driven guidance to help you match equipment to real-world conditions, never pushing a product that does not fit.
