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.
- This transformer is divided into single-phase transformers and EI type dry-type iron core transformers.
- 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.
- 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.
- 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.
- 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.
- 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).
- 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.
