Product Introduction
The 100 Kva 3 Phase Transformer is crafted from high magnetic induction silicon steel, with a step-by-step lamination process that minimizes no-load loss and operational noise. Its coil windings are made of premium copper electromagnetic wire and adopt a segmented winding structure, enabling it to withstand high-voltage and high-current impacts more effectively. The enclosure of this transformer is constructed from high-strength cold-rolled steel plates, finished with a three-layer epoxy protective coating, which delivers excellent resistance to corrosion and sand erosion. Premium materials, sophisticated craftsmanship, and stringent quality control are the cornerstones of the 100 Kva 3 Phase Transformer's superior performance and reliability.

Customer Case
Hozee Electric customized a 100 Kva 3 Phase Transformer for a client in Kazakhstan. To address the region's frequent sandstorms, voltage fluctuations, and extreme temperature variations, our engineers implemented targeted design enhancements. These modifications ensure the transformer operates stably and reliably under harsh environmental conditions, meeting the client's specific operational needs.
cored winding
The transformer adopts a stepped foil winding structure, reducing leakage inductance to 60% of that of conventional designs. Meanwhile, low-loss silicon steel sheets (with iron loss ≤ 0.9W/kg) are used, which lowers no-load loss by 15% compared to traditional products and significantly improves voltage stability. This combination of design and material advantages ensures efficient and stable operation.
Transformer body drying
Transformer oil tank:
The oil tank is made of 5mm-thick high-strength cold-rolled steel plates, coated with a three-layer epoxy protective coating with a dry film thickness of approximately 340-360 μm, providing enhanced resistance to corrosion and sand. It features a welded tank body and silicone rubber sealing rings, with an overall front-sealed structure that achieves an IP54 or higher protection level, effectively preventing dust and water ingress.
The transformer is packaged with an iron frame structure, where the transformer and the frame are firmly fixed together to prevent shaking or collision during transportation. This iron frame packaging allows for double-layer stacking of transformers, optimizing space utilization and reducing transportation costs for our clients.
After sales service: The after-sales service of transformers is the key to ensuring the long-term stable operation of equipment
Preventive maintenance: Conduct inspections 1-2 times a year in accordance with contract agreements or industry standards, checking oil level, oil temperature, insulation status, and fastener tightness. Timely clean dust and replace aging seals. Troubleshooting: Respond promptly upon receiving repair requests (e.g., on-site arrival within 24-48 hours), investigate faults such as short circuits, oil leaks, and insulation breakdowns, and replace damaged components (e.g., windings, bushings, cooling fans). Oil treatment: Regularly test the oil quality of oil-immersed transformers (including dielectric loss, moisture, impurities, etc.), and perform oil filtration or replacement when necessary to ensure insulation performance.

Provide 24/7 hotline support to answer user questions or offer remote guidance for simple troubleshooting. For major faults, dispatch a technical team for on-site repairs. If factory repair is required, we will be responsible for transportation and reinstallation/commissioning after repair.
We maintain a dedicated spare parts warehouse, providing long-term supply of common vulnerable parts (e.g., fuses, thermostats, gaskets) and key components (e.g., iron cores, windings), significantly shortening maintenance cycles and minimizing downtime.
Provide training for user operators and maintenance personnel, covering equipment principles, daily inspection methods, and emergency response procedures. Supply complete technical documents, including installation manuals, maintenance manuals, circuit diagrams, and spare parts lists, to facilitate user self-management.
During the warranty period (usually 1-5 years), any faults caused by product quality issues will be repaired or replaced free of charge. We also provide free on-site service for some product lines.
Condition monitoring: Provide online monitoring systems for large transformers (e.g., oil chromatography analysis, partial discharge monitoring) to remotely monitor equipment status in real-time and issue early warnings for potential faults. Transformation and upgrading: Offer technical transformation solutions (e.g., increasing cooling capacity, upgrading insulation materials) based on power grid expansion and environmental changes to extend equipment service life. Scrap and recycling: Assist in compliant scrap disposal and recycle reusable materials (e.g., iron cores, metal enclosures) when equipment reaches the end of its service life.
