Rectifier Transformer — Product Overview
The DG single-phase dry-type isolation transformer is produced using high-quality materials and advanced technology, and it can penetrate deep into the load center; Mainly used for various power supply places with AC frequency of 50-60Hz and voltage not exceeding 500V; The allocation of various input and output voltages, connection groups, and tap line group capacities of the product can be carefully designed and manufactured according to user requirements; It has the advantages of fire prevention, moisture resistance, safety and reliability, energy conservation, and easy maintenance. Widely used in machine tool matching, distribution places in subways, high-rise buildings, airports, stations, docks, industrial and mining enterprises, and tunnels.
VoltCloud Electric engineers and manufactures this equipment for utility, industrial and renewable-energy projects. Every unit is routine-tested before shipment and delivered with test records and export documentation. Ratings shown below are from our current production data — non-standard capacities, voltage ratios and loss classes are engineered to order.
Key Specifications
| Item | Value |
|---|---|
| Wiring terminals | small power, beautiful appearance, excellent pressure resistance, temperature resistance and flame retardant performance. High power uses high-quality copper bars. |
| Iron feet | mainly using CNC bending cold plate, with environmentally friendly electroplating options such as colorful (golden), blue zinc (silver white), white zinc (ivory white), and surface anodizing (black). |

Features & Construction
- This transformer is divided into single-phase transformers and EI type dry-type iron core transformers.
- The coil is made of H-grade or C-grade enameled flat copper wire winding, arranged tightly and evenly, without insulation layer on the surface, and has excellent beauty and good heat dissipation performance.
- The fasteners of the transformer core column are made of non-magnetic materials to ensure that the transformer has a high quality factor and low temperature rise, ensuring good filtering effect.
- Compared with similar domestic products, this transformer has the advantages of small size, light weight, and beautiful appearance, which can be comparable to well-known foreign brands.
Product Details
The iron core is made of high-quality and low loss cold-rolled oriented silicon steel sheets, mainly made of 0.3 and 0.35 thick H18, H14, H12, Z11 high-quality silicon steel sheets. We select the most suitable materials according to customer requirements and usage conditions to achieve the best performance design of the transformer.
After the coil and iron core of the transformer are assembled into one, they undergo a process of pre drying, vacuum impregnation, and hot curing. H-grade impregnation paint is used to firmly bond the coil and iron core of the transformer, which not only greatly reduces the noise during operation, but also has a very high heat resistance level, ensuring that the transformer can operate safely and noiselessly at high temperatures.
