The 35kV and below SC(B)10～18 series dry-type transformers are mainly applied in power transformation and distribution systems. Dry-type transformers are most suitable for environments with high fire protection requirements, large load fluctuations, and harsh conditions of pollution and humidity. The products have been used in major national projects such as the Three Gorges, Yellow River Xiaolangdi, Beijing Olympic Bird's Nest, Capital Airport, Beijing Subway, Ningde Nuclear Power, Shanghai World Expo Pavilion, and Hangzhou Asian Games Venue. The dry-type transformer products have passed Italian CESI certification. The company has obtained integrated management system certifications for quality, environment, and occupational health and safety. "Rongpai" Tianyu dry-type transformers have repeatedly passed type tests and special tests at the National Transformer Quality Supervision and Inspection Center.

Scope of Application:

Power Sector: Such as thermal power, hydropower, nuclear power, gas power generation, wind power generation, etc.

Petrochemical Sector: Such as oil extraction, oil refining, natural gas extraction, etc.

Transportation Sector: Such as subways, light rail, airports, ships, highways, urban transportation, etc.

Construction Sector: Such as high-rise buildings, commercial plazas, communication buildings, residential communities, etc.

Industrial and Mining Sector: Such as special equipment power supply, factory relocation and transformation, mining area power usage, metallurgy, etc.

Functional Features:

Safe, flame-retardant, fireproof, pollution-free, and can be directly installed at the load center

Maintenance-free, easy installation, low comprehensive operating costs

Excellent moisture resistance, low loss, low partial discharge, low noise, strong heat dissipation capability; can operate at 150% rated load under forced air cooling

Equipped with a complete temperature protection control system to provide reliable assurance for safe transformer operation

Product Advantages:

The transformer core adopts high-permeability, low-loss grain-oriented cold-rolled silicon steel sheets with a 45° fully mitered joint and stepped seven-piece, seven-step structure. The core columns use the internationally advanced TENAX high-strength binding tape process, reducing hysteresis loss and noise

The low-voltage coils of the dry-type distribution transformer are wound on an imported French SCAL foil winding machine, with inter-layer insulation using Class H DMD epoxy resin pre-impregnated material. After winding, the upper and lower end faces are strictly encapsulated with epoxy resin to prevent dust and moisture from entering the winding interior, ensuring insulation performance

The enclosure material is aluminum alloy or stainless steel. Aluminum alloy material undergoes oxidation treatment to ensure long-term use without discoloration

During product assembly of the dry-type transformer, the upper and lower yoke pads and coils are compressed using high-elasticity, aging-resistant silicone rubber sheets combined with bolts, improving transformer stability and overall mechanical strength. All leads are machined, burr-free, and aesthetically neat
