干式电力变压器是一种不使用绝缘油的电气设备，主要用于高层建筑、发电厂、商业中心等需要防火、防爆、防潮的场所，采用自然冷却或空气冷却。其铁芯和绕组无油绝缘，外壳采用不锈钢、冷轧板或铝合金制成，具有阻燃、防爆、免维护等特点。
Dry type power transformer is a type of electrical equipment that does not use insulating oil. It is mainly used for high-rise buildings, power plants, commercial centers, and other places that require fire, explosion, and moisture protection through natural cooling or air cooling. Its iron core and winding have no oil insulation, and the shell is made of stainless steel, cold-rolled sheet or aluminum alloy, with flame retardant, explosion-proof, and no maintenance requirements.
Model Number: SCB10、SCB11、SCB13 Service Voltage: 6.6-35kV
Rated Capacity: 30-5000kVA Phase: Three
The common structures of dry-type transformers include open type, closed type, and cast type, each suitable for different environmental conditions to meet diverse usage needs. The cast winding is made of epoxy resin or other resins to achieve the main insulation function; The closed winding is enclosed in a shell and is not directly connected to the outside atmosphere. This design is mainly used for mining equipment, as its sealing and heat dissipation conditions are relatively poor, but it has explosion-proof characteristics.
With 20 years of focus on transformers, Chuanglian Transformer has provided professional project guidance, equipment production, production line construction, management and operation and other product services to more than one million customers, and together with them demonstrated the power of Chinese transformer brands.
