Dry type transformer is in accordance with GB 6450-86 ¡ DegreeDry-type Power Transformer¡±, GB 10228-1997 ¡ DegreeTechnical Parameter and Requirement of Dry-type Power Transformer¡±and GB 1094.1-1996 ¡ DegreePower Transformer Section 1 General¡±, and it is the Grade F or H insulation dry-type power transformer cast and molded by epoxy resin. The product has the following advantages: 1.High mechanical strength and strong short circuit resistance ability; 2. Good moisture resistance and run with 90% humidity; 3. Advanced structure, small dimension, light weight and low partial discharge; 4. High insulation level and equal electric field distribution; 5. Easy maintainability; 6. Strong heat dissipation, run with 150% rated load under forced air cooling; 7. Fireproof, explosion-proof, pollution-free and low-noise and able to be directly installed in the load center. The product can be widely used in places with high fireproofing requirements, such as power transmission and transformation system, high building, commercial center, sport stadium, petrochemical enterprise, metro, station and airport. In China, the epoxy resin cast dry type power transformer has the richest manufacturing experience and the best running performance. dry type electrical transformers Specifications: The core selects high quality cold rolled grain oriented silicon steel sheet. 45oC inclined seam. Five steps to fold the iron. Core column and iron yoke are multistage circular cross section shape,. So that the transformer can get lower no-load loss and noise. According to the size of the transformer capacity, high-voltage wire is the double glass enameled copper wire, between layers is the H-class glass fiber cloth and glass mat insulation. The low-voltage part is winded by copper foil, between layers is the epoxy resin presoak cloth insulation which has very high mechanical strength and the ability of resisting the sudden short circuit. Clip pieces are the low magnetic steel sheets and coordinate structure. They are processed by sandblasting and coating which makes their overall structure looks beautiful and has high mechanical strength. Every phase is equipped with independent cooling fan and split type thermostat which can reduce the temperature effectively and improve the transformer output capacity to guarantee the operation of transformer. The insulation heat resistance levels of the dry type transformer are Level B, Level H, Level F, etc. The heat temperature is 130oC, 155oC and 180oC respectively. This series product selects new materials and new process, so the SG10 type has the Level H of the insulation heat level which is more reliable and safer. Dry type transformer Specification&Parameters: Capacity: 10-2500KVA Phase: Three-phase Primary Voltage: 35kV All voltage grades including 35KV and less Secondary Voltage: 0.4KV or 10KV Voltage regulating range: ¡À5%,¡À2¡Á2.5% or according to the clients¡¯ requirements Voltage regulating method: Non-excited voltage regulation and on-load voltage regulation Connection set: Dyn11,Yyn0,Yd11 Several connection sets, including Dyn11, Yyn0 Frequency: 50Hz or 60Hz
