Product Description

Cast Resin Dry type transformer
Model : SC Type 6~10kV
Product overview
Epoxy resin dry-type transformers from TAILI Electric, is difference from oil type transformer is that it must be installed inside with the core and winding are not impregnated in insulating oil, are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, etc. Its cooling method can be divided into natural air cooling (AN) and forced air cooling (AF). With natural air cooling, the transformer can operate continuously at rated capacity for a long period of time. With forced air cooling, the transformer output capacity can be increased by up to 50%. It is suitable for intermittent overload operation, or emergency accident overload operation; because of the load loss and impedance voltage increase during overload, it is in non-economic operation, so it should not be in long time continuous overload operation.

Features
1.Safe, fireproof, pollution-free, can be run directly in the load center.
2.Adopt domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life.
3. Low loss, low noise, obvious energy-saving effect, maintenance-free.
4. Good heat dissipation performance, strong overload capacity, and can increase capacity operation when forced air cooling.
5. Good moisture-proof performance, adapt to high humidity and other harsh environment operation.
6. It can be equipped with perfect temperature detection and protection system. Adopting intelligent signal temperature control system, it can automatically detect and display the respective working temperature of three-phase winding, and automatically start and stop the fan, and have function settings such as alarm and tripping.
7. Small volume, light weight, occupying less space and low installation cost.

Structure

High temperature resistant coil
The component has a well - designed structure. Its advanced materials enable it to resist temperatures up to 150 °C. The high - quality insulation not only offers good electrical insulation but also makes it less likely to age. This, along with its structure, greatly improves the machine's life and ensures reliable operation in tough conditions.

Core
The core conducts magnetic flux for energy transfer between windings. An AC in the primary creates a magnetic field guided by the core to the secondary, inducing an EMF. It offers benefits: high - permeability materials reduce excitation current and size; low - loss design cuts energy use; good mechanical strength ensures reliable operation; low noise suits quiet areas; excellent thermal stability allows wide - temperature operation.

Resin artcract
Resin in cast resin dry - type transformers serves multiple functions. It provides insulation, mechanically fixes components, keeps out moisture, and aids in heat dissipation. Its advantages include good electrical performance, excellent mechanical properties, chemical corrosion resistance, good processability, and environmental friendliness, all of which contribute to the reliable operation and long - term performance of the transformer.

Exhaustion hole
The exhaustion holes are strategically placed on the enclosure. They function by allowing hot air to escape, effectively reducing internal temperature. This temperature reduction boosts the transformer's ability to handle overloads, as cooler components can better withstand higher currents, ensuring stable operation.

Cross flow cooling fan
The cross - flow cooling fan is installed adjacent to the windings. Its blades are designed to direct air across a wide heat - dissipation area. As the fan operates, it accelerates air movement, quickly removing heat. This reduces heat increase, preventing component overheating and enhancing the transformer's reliability for stable long - term operation.
