How is Daelim Cast Coil Transformer Constructed & Designed?

We use a vacuum-casting process for our cast coil transformer, to ensure the primary and secondary windings are fully encapsulated in a solid epoxy resin block. Our method creates a void-free structure, effectively minimizing partial discharges and enhancing long-term reliability.

Casting offers the highest level of protection for the windings, making them perfect for harsh environments, such as areas with airborne dust or high humidity. Plus, the fiberglass reinforcement in the casting gives the transformer incredible mechanical strength.

Our cast coil power transformers are designed to step down high voltages from transmission and distribution systems to lower voltages, which can then be used in commercial, industrial, institutional, or utility applications.

They can be applied for indoor and outdoor use and the low maintenance cost ensures reliable service. Unlike our oil-filled transformer that require oil or other cooling liquids, our dry-type cast coil transformers use environmentally safe insulation systems.

Performance & Advantages of Daelim Cast Coil Transformer

Our cast coil transformer design focuses on durability and performance, offering several key advantages for your power systems. Here’s how their construction makes them stand out:

• Short-time overload capacity: Unlike oil-cooled units, our cast coil transformers handle short-time overloads better, thanks to the resin encapsulation around the windings. This gives them extra strength to handle sudden power surges.
• Temperature control: Our cast coil transformers come with built-in probes that monitor the temperature of the windings. The temperature is displayed on a digital screen, so you can always stay informed about the system’s health.
• Low maintenance: Our cast coil transformers are designed to require minimal upkeep. A simple routine inspection and a quick wipe-down are usually all that's needed to keep them running smoothly.
• Low noise levels: You’ll appreciate the quiet operation of our cast coil transformers. They produce very little noise, making them a great choice for areas where noise reduction is important.
• Low fire hazard: Safety is a top priority, so our cast coil transformers are self-extinguishing and have a much lower fire hazard than other transformer types.
• Environmentally friendly: Our transformers are built with environmentally safe materials, so you can feel confident that they meet modern standards for sustainability and safety.
• Low installation cost: With our cast coil transformers, you’ll save on installation costs. They’re easy to install and can be placed closer to the load, reducing both time and expense.
• Resistant to moisture: These transformers are resistant to moisture and atmospheric contaminants, making them ideal for outdoor or high-humidity environments.
• High-impact loading: Our cast coil transformers are built to withstand high-impact loading, making them robust enough for challenging industrial settings.
• Operate under heavy vibrations: Some of our models are designed to operate smoothly even under heavy vibrations, ensuring reliable performance in demanding conditions.
