Product Description

 

Non-encapsulated dry transformer is an advanced transformer, which adopts dry winding and oil-immersed core technology, mainly composed of high voltage winding, low voltage winding, iron core and shell.
The high voltage and low voltage windings of non-encapsulated dry transformer are dry insulation structure, which can not only improve the insulation strength, but also prevent insulation aging. The iron core is an oil-immersed design, which reduces the power consumption of the transformer, and has lower noise and more stable operation. The shell of the non-encapsulated dry transformer is made of special metal materials and has the characteristics of fire, moisture and corrosion protection.
The non-encapsulated dry transformer converts the high voltage of the transmission line to the low voltage through the electromagnetic induction between the high voltage winding and the low voltage winding to supply the end user. In addition, the transformer core can also effectively reduce the loss of current, thereby reducing power consumption and operating costs.

Product Features

Class H insulation: Dry type transformer insulation heat resistance grade F, H, C, etc. The product uses DuPont NOMEX paper as the main insulation material, its insulation level has reached H level, the key parts of the grade has reached C level.
Safety: All the insulating materials of the product are non-combustion-supporting, self-extinguishing, non-toxic, and almost no toxic smoke is produced when it is burned for a long time at 800 ° C.
Reliablity: Excellent anti-corrosion performance (moisture-proof, anti-gas, anti-salt spray), can withstand thermal shock, never crack.
Environmental protection: It will not cause environmental pollution during manufacturing, transportation, storage and operation, and can be decomposed and recovered after reaching the life period.
Strong overload capacity: Strong overload capacity, fast heat dissipation, long-term safe and reliable operation under 130% overload.

Service Environment

1. Altitude ≤1000m, ambient temperature: -25ºC--40ºC, indoor type.
2. For air self-cooling and forced air cooling transformers, it is necessary to ensure that the transformer has good ventilation capacity.
3. When the transformer is installed in the basement or other environments with poor ventilation capacity, heat dissipation and ventilation devices must be added.
4. Protection levels are IP00, IP20, IP23 and other types.
5. When the altitude is >1000 meters or the ambient temperature is greater than 40 ° C or less than -25 ° C, the product must be in accordance with the requirements of GB1094.11 Power transformers Part 11: Dry-type transformers to adjust the relevant ratings accordingly.
