Zhangbei Transformer Manufacturer Nationwide Shipped 35KV Dry type Transformer Price

Description :

　　35kV dry-type transformer product introduction:

　　1. The high-voltage winding is made of enameled copper wire, while the low-voltage winding is made of copper foil. High voltage winding is made of glass fiber mesh cloth board, which is poured with imported epoxy resin in a vacuum state. After curing, it forms a sturdy whole with high mechanical strength, low partial discharge, and high reliability.

　　2. Flame retardant, explosion-proof, environmentally friendly, and can be installed in load centers.

　　3. The coil does not absorb moisture. The iron core and clamps can operate in harsh environments with relative humidity and other adverse conditions after special processing. Intermittent operation does not require dehumidification treatment.

　　4. Strong ability to withstand sudden short circuits, high level of resistance to lightning and operational wave impacts, and high product overload capacity.

　　5. The resin insulation layer on the inner and outer sides of the coil is thin and has good heat dissipation performance. The cooling method generally adopts air re ignition cooling (AN). For transformers of any protection level, an air cooling system (AF) can be configured

　　6. Low loss, good energy-saving effect, economical operation, and maintenance free.

　　7. Small size, light weight, small footprint, and easy installation.

　　8. The temperature control system consists of a temperature controller and PTC temperature measuring elements installed at the upper end of the low-voltage winding, which is the hot spot of the product, to achieve temperature measurement and control of the transformer. If the temperature of the transformer is too high due to overload operation or malfunction, the temperature controller will issue an alarm signal. When the temperature exceeds the safe value, it will trip automatically. When forced air cooling is used, the temperature controller will determine the input or switching of the cooling fan based on the winding temperature.

　　9. The temperature display system directly displays the hot spot temperature of the winding during the operation of the transformer and can be used in conjunction with the temperature control system.

　　Cooling method for 35kV dry-type transformer

　　When the temperature of a 35kV dry-type transformer exceeds the insulation withstand temperature, it can cause insulation damage, affecting the safe operation and service life of the dry-type transformer. Therefore, a suitable cooling device should be installed on the 35kV dry-type transformer to keep the winding temperature within the allowable range. The commonly used cooling methods for dry-type transformers include natural air cooling and forced air cooling. The rated capacity of dry-type transformers is the capacity under natural air cooling. The output capacity of 35kV dry-type transformers with forced air cooling can be increased by 40% to 50%, and can be used for intermittent overload operation or emergency overload operation. The fan for forced air cooling is generally installed at the lower part of the dry-type transformer.
