Factory Direct Selling Price Three Phase Dry Type High Voltage Transformer 500kva 12KV

Dry-type transformers and oil-immersed transformers are the two most commonly used types of transformers. Compared with oil-immersed transformers, dry-type transformers have better fire resistance and are often used in places with high fire protection requirements, such as hospitals, airports, and train stations.

Product Description

Project Dimension	Standard/General Product Introduction	Customizable Options & Solutions
Core Overview	Dry-type transformers use air or resin as insulation medium. They feature fire resistance, explosion proof, no pollution and maintenance-free operation, making them an ideal choice for indoor locations requiring safety and environmental protection.	Provide full-range customization from basic parameters to special environments to meet precise requirements.
Basic Electrical Parameters
Rated Capacity	Common range: 30kVA to 5000kVA	Can conduct non-standard capacity design to meet special load requirements
Voltage Class	Primary side: 10kV, 11kV, 20kV, 35kV, etc.; Secondary side: 0.4kV, 6.3kV, 10.5kV, etc.	Supports design of any standard or non-standard voltage combination
Frequency	50Hz or 60Hz	Can be designed as 50/60Hz universal type
Insulation Class	Usually Class F (155℃) or Class H (180℃), providing high temperature rise margin	Can customize higher insulation class (e.g., Class C) for maximum reliability requirements
Performance & Loss	Complies with standards such as IEC 60076, with energy efficiency levels including SCB10/11/12/13/14/15	Can optimize design to achieve specific energy efficiency targets (e.g., meeting IE3, IE4 energy efficiency standards)
Structural Design & Materials
Winding Type	Resin-cast type: High mechanical strength and moisture resistance; Impregnated type (open ventilation): Good heat dissipation and lower cost	Optional or hybrid winding process can be selected according to application environment (e.g., humidity, corrosion)
Winding Material	Electrolytic copper (mainstream)	Can choose copper or aluminum windings to balance cost and performance
Core Material	High-quality cold-rolled grain-oriented silicon steel sheet	Can be upgraded to high-performance silicon steel or amorphous alloy core, significantly reducing no-load loss and noise
Cooling Method	Natural air cooling (ANAN)	Can customize forced air cooling system (AF/AF) to improve short-time overload capacity
Protection Level	Common indoor grades: IP20 (finger protection), IP23 (drip proof)	Can be customized up to IP54 and above for harsh indoor environments with heavy dust and high humidity
Enclosure	Usually conventional protective cover	Can customize stainless steel enclosure, noise-reducing enclosure or aesthetic decorative enclosure for public place installation
Special Applications & Environmental Adaptability
Safety & Environmental Protection	Oil-free and non-combustible, suitable for high-rise buildings and underground facilities	Can add special coatings for corrosion resistance (chemical industry), salt spray resistance (coastal areas) or mold resistance environments
Low Noise Requirement	Standard noise level	Achieve low-noise or silent operation through magnetic density optimization and shock absorption design, suitable for hospitals and schools
Plateau & Temperature Difference	Suitable for conventional altitude	Designed as plateau-specific type to adapt to low air pressure and large temperature difference environments
Certification & Standards	Complies with IEC standards and routine factory tests	Can obtain certifications such as CE, UL, CSA, GOST-R according to target markets, and provide complete type test reports
