2.45 degree fully oblique step seam iron core
The iron core is made of high-quality, high magnetic grain oriented cold-rolled silicon steel sheets, with 45 degree fully oblique step seams and a special square tube pull plate structure. The core column is tied with insulation tape; The surface is coated with special resin to prevent moisture and rust, effectively reducing no-load loss, no-load current, and core noise.
3. Multilayer segmented cylindrical high-voltage coils
The high-voltage winding conductor is wound with F-grade insulated copper wire, reinforced with long and short cut glass fiber felt as filler, and poured with epoxy resin mixture under vacuum (1-3mbar). Effectively suppress the occurrence of partial discharge, with a partial discharge amount not exceeding 5PC.
4. Longitudinal air duct foil structure low-voltage coil
The low-voltage coil is wound using high-quality foil conductors on an automatic foil winding machine, with argon arc protection welding and high welding accuracy; Pre impregnated DMD serves as interlayer insulation, with pre impregnated fiberglass cloth used for insulation both inside and outside. The upper and lower ends are sealed with epoxy resin, and then cured as a whole in a curing furnace, with good moisture resistance.
5. Durable and aesthetically pleasing protective casing
IP20 can prevent solid particles with a diameter greater than 12mm from entering and resist accidental impacts; IP23 not only has the function of IP20, but also prevents water droplets from flowing in at an angle of 60 degrees to the vertical line, making it suitable for outdoor installation and use; Customizable.
Dry type transformer is a type of transformer where the iron core and winding are not immersed in insulating liquids. The epoxy resin cast dry-type transformer products produced by our company are designed according to IEC international standards and current national standards. Their manufacturing technology is advanced, and they are safe and environmentally friendly products with low loss, low partial discharge, and low noise.
The dry-type transformer produced by Shanghai Zhiyou Company is safe, flame-retardant, fire-resistant, pollution-free, and can be directly installed in the load center. Maintenance free and easy to install. Good moisture-proof performance, can be put into operation without pre drying after shutdown. Low loss, low partial discharge, low noise, and can operate at 120% of rated load under forced air cooling conditions. Equipped with a comprehensive temperature protection and control system, it provides reliable guarantee for the safe operation of transformers.
Shanghai Zhiyou Company, the famous brand in China's transformer industry, will do our best to provide our customers with the most reasonable transformer prices, high-quality services, and detailed technical support.
Performance characteristics
1. High reliability: The temperature control adopts an intelligent temperature controller, which is easy to maintain and improves the safety and reliability of transformer operation. Small partial discharge: The winding is wound with copper wire or copper foil, filled and wrapped with fiberglass felt, and wound with epoxy resin in a vacuum state. After curing, it forms a sturdy cylindrical whole, with small partial discharge and high reliability. Simultaneously flame retardant, explosion-proof, and non polluting to the environment.
2. Strong resistance to sudden short circuits: The high-voltage winding of the product is made of epoxy resin vacuum casting, with small partial discharge and high electrical strength of the coil. The inner and outer walls of the winding are made of fiberglass mesh plates, which increases the mechanical strength of the coil and improves the product's ability to resist sudden short circuits.
3. Low cost: The iron core is made of imported high-quality cold-rolled silicon steel sheets, with a three-stage fully inclined seam structure. The surface is coated with epoxy resin, reducing no-load loss, no-load current, and iron core noise.
4. Strong short-circuit resistance: The high-voltage winding of the product is made of epoxy resin vacuum casting, with small partial discharge and high electrical strength of the coil. The inner and outer walls of the winding are made of fiberglass mesh plates, which increases the mechanical strength of the coil and improves the product's short-circuit resistance.
5. Good thermal stability: The coil and lead wire are made of copper wire, and axial air ducts are added inside the coil, leaving sufficient temperature rise margin. The heating part and the hottest spot of the product are strictly controlled for temperature rise, and the main temperature rise indicators of the product are at least 5 degrees lower than those of international standards.
6. Low temperature rise, long service life: The product has low temperature rise, strong heat dissipation ability, and can operate at 150% of rated load under forced air cooling conditions. An optional temperature control and protection system with comprehensive performance can provide reliable guarantee for the safe operation of transformers.
7. Maintenance free: Dry type transformers have no oil, and 1250kva dry-type transformers are reasonably priced, eliminating the need for regular oil changes and maintenance of the product.
8. Beautiful appearance: The core column of the product is tied with F-grade weft free straps, and the surface of the clamps and fasteners is specially treated to make the product more beautiful.
Usage environment
1. Installation location: indoor;
2. Altitude: less than 1000 meters (special design is required when it is greater than 1000 meters);
3. Environmental temperature: -25 ºC~+40 ºC;
4. The waveform of the power supply voltage is approximately a sine wave; The three-phase power supply voltage is roughly symmetrical;

For both air-cooled and forced air-cooled transformers, it is necessary to ensure that the transformer has good ventilation capacity. When transformers are installed in basements or other environments with poor ventilation capacity, heat dissipation and ventilation devices must be added. Protection levels include IP00, IP20, IP23, and other types.
When the altitude is greater than 1000 meters or the ambient temperature is greater than 40 ºC or less than -25 ºC, the product must adjust the relevant rated values in accordance with the requirements of GB1094.11 Power Transformers - Part 11: Dry type Transformers.
