3 Phase Electrical Transformer 20KV Dry Type Transformer 25 KVA Product introduction
Dry type transformer is in accordance with GB 6450-86 “Dry-type Power Transformer”, GB 10228-1997 “Technical Parameter and Requirement of Dry-type Power Transformer”and GB 1094.1-1996 “Power 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.
