🔬 Why Cast Resin? The Technology Behind the Safety

Unlike traditional oil-filled units, Cast Resin Dry-Type Transformers utilize a specialized epoxy resin mixture to encapsulate the windings. This creates a monolithic, moisture-proof, and fire-resistant core that is ideal for sensitive environments.

⚡ High Dielectric Strength

Our vacuum casting process ensures zero air bubbles in the resin, preventing partial discharge and extending the insulation life to over 30 years.

🔥 Fire & Explosion Proof

Cast resin is self-extinguishing. In the event of an external fire, the transformer will not support combustion or release toxic gases, making it mandatory for high-rise buildings.

🌱 Environmental Integrity

Zero oil means zero risk of groundwater contamination. These units are 100% recyclable at the end of their lifecycle, aligning with ESG (Environmental, Social, and Governance) goals.

Technical Roadmap: The Evolution from SCB10 to SCB18

We are constantly pushing the boundaries of Information Gain in energy efficiency. Our technical roadmap highlights the transition from standard silicon steel cores to Amorphous Alloy cores, which reduce no-load losses by up to 70%.

Frequently Asked Questions

Q1: What is the main advantage of Cast Resin over Oil-Immersed Transformers?

A: The primary advantage is safety and placement flexibility. Cast resin transformers are fire-resistant and environmentally friendly, allowing them to be installed inside buildings, hospitals, and underground stations where oil-filled units are prohibited due to fire and leakage risks.

Q2: Can Henan Pirooz provide custom OEM designs?

A: Yes. We specialize in custom voltage ratios, specific vector groups (like Dyn11 or Yyn0), and specialized cooling systems (AN/AF). Our engineers can design equipment tailored to the unique grid requirements of any country.

Q3: How do you ensure the quality of your epoxy resin?

A: We use premium F-class or H-class insulation materials and perform vacuum pressure impregnation (VPI) or vacuum casting to ensure the resin is completely homogenous, protecting the coils from moisture and chemical contaminants.

Q4: What is the typical lead time for an export order?

A: Depending on the complexity and KVA rating, lead times typically range from 4 to 8 weeks. Our efficient Henan supply chain allows us to maintain faster turnaround times than many European or North American manufacturers.
