Modern technology that saves you money should be used in your power grid. Our Cast Resin Amorphous Alloy Transformer blends cutting-edge amorphous metal core technology with advanced cast resin insulation. Compared to standard silicon steel transformers, it has 70–80% less no-load losses. This transformer is a big step forward in environmentally friendly power transfer because it has a working efficiency of 98.5 to 99.2% at full load. With the help of our 15 senior engineers and more than 120 sets of advanced manufacturing equipment, such as CNC automatic winding machines and microcomputer-controlled gradient curing furnaces, we can make transformers that meet the strictest international standards and work for more than 30 years without any repairs.
The answer you're looking at is new and will solve your most important power distribution problems.
The product has an amorphous metal core made from bands with iron, nickel, cobalt, boron, and carbon that have been carefully mixed. This atomic structure that isn't solid wastes a lot less energy when it's working.
The cast resin insulation method does not pose the risk of fire or explosion like oil-filled units do. There is no need to worry about putting these transformers inside.
The technology delivers tangible benefits:
Our manufacturing facility holds 18 patents and operates under ISO 9001 quality management standards. Every transformer undergoes rigorous testing before delivery.

Q: What is a product?
t's a high-tech dry-type transformer that combines two ground-breaking technologies. The non-crystalline material bands in the amorphous metal core make energy waste much smaller. Cast resin insulation doesn't use oil, so it is safer and better for the earth. You get the most reliable service with the lowest possible running costs.
Q: How much energy can I save?
When compared to regular silicon steel transformers, no-load losses drop by 70–80%. Efficiency is between 98.5 and 99.2% at full load. Every year, a normal 1000kVA machine saves a lot of kilowatt-hours. Most of the time, you'll get your money back in three to five years just from lower power bills.
Q: Are these transformers safe for indoor installation?
Of course. The cast plastic insulation doesn't catch fire and goes out on its own, so it meets UL94 V-0 standards. There isn't any oil that could leak or catch fire. They can be put in basements, underground substations, or buildings that don't have special fire control systems. Because they make less than 45dB of noise, they can be used in places where noise is a problem.
Q: What maintenance do they require?
None. The design provides 30+ years of maintenance-free operation. There's no oil to test or replace, no moisture ingress issues, and no special environmental controls needed. You eliminate ongoing maintenance costs and avoid production disruptions for service.
Q: Can they handle harsh environments?
Yes. Operating range extends from -40°C to +40°C ambient temperature. The cast resin construction resists moisture (water absorption under 0.1%), dust, and chemical exposure. They're ideal for coastal areas, industrial facilities with corrosive atmospheres, and locations with extreme temperature variations.
Q: What capacity ranges are available?
We manufacture units from 30KVA to 31500KVA. Whether you need a small distribution transformer or large capacity for industrial applications, we have suitable options. Custom voltage configurations accommodate any primary (10/20/35kV) and secondary (0.22-1.14kV) requirements.
Q: Do they work with renewable energy systems?
Perfectly. The amorphous core handles variable loads from solar and wind generation efficiently. Low harmonic distortion characteristics suit power electronics-heavy systems. Many photovoltaic farms and wind installations use these transformers for grid connection.
Q: What certifications do your transformers carry?
Our products meet IEC60076, ANSI, IEEE, GB, and CSA standards. We hold ISO 9001, ISO 14001, and OHSAS 45001 certifications. All products carry National CCC Mandatory Certification. CE and CSIT approvals cover international markets. We're qualified suppliers for State Grid and Southern Power Grid.
Q: How long does delivery take?
Production time varies by capacity and specifications, typically 6-12 weeks. Our track record shows consistent on-time or early delivery. We maintain open communication throughout production and coordinate shipping to meet your project schedule.
Q: Can you customize transformers for special requirements?
Yes. Our engineering team designs solutions for unique environmental conditions, special voltage requirements, and country-specific standards. Whether you need altitude compensation, special cooling configurations, or specific vector groups, we'll engineer the right solution.
