DESCRIPTION
Product Introduction
AISITE 35kV dry type transformers are made with a magnetic core from laminated grain-oriented silicon steel. Additionally, HV winding can also be wound from insulated by an inter-layer film, pre-impregnated with heat-activated epoxy resin. The ends of the windings are protected and insulated using Class F materials. With outstanding resistance to harsh industrial atmospheres, excellent dielectric withstand and very good resistance to short-circuit conditions are ideal for industrial and commercial use.
Features
1.High safety performance: Dry-type transformers are flame-retardant, fire-proof, explosion-proof, and pollution-free, and can be safely installed directly at the load center.
2.Low maintenance cost: The dry type transformer is maintenance-free(No need to regularly change insulating oil or deal with oil contamination), and the comprehensive operating cost is significantly reduced.
3. Good moisture resistance: It can still operate normally in a 100% humidity environment, and can be put into use quickly without pre-drying after shutdown.
4.Efficient heat dissipation capacity: It has strong heat dissipation capacity and can operate at 150% of the rated load even under forced air cooling conditions.
5.Reliable temperature protection: Equipped with a complete temperature protection control system, it provides solid protection for the safe operation of the transformer.
6.Compact size and light weight: Dry-type transformers are small in size, light in weight, occupy less space, and have relatively low installation costs.

FAQ
Q1: Safer for indoor use than oil-filled transformers?
Yes. No flammable oil, self-extinguishing resin (IEC 60076-11), lower fire risk.
Q2: Maintenance frequency?
Daily inspection: once a week, check the transformer's appearance, temperature, noise, etc.
Monthly inspection: Carry out once a month to check the insulation resistance, grounding resistance, etc.
Q3: Maximum operating temperature?
Rated for 40℃ ambient. At 50℃: ≈ 90% load capacity. Cooling kits available.
Q4: Suitable for humid/coastal sites?
Yes. IP54 protection >95% humidity. Anti-corrosion coating for salt air.
Q5: Space needed for installation?
30% smaller than oil types. Minimum 500mm clearance from walls (NFPA 70).
