1.SG10 Type H-Class Insulation Dry-Type 11Kv 33Kv Power Transformer
01) The core is made of cold-rolled silicon steel sheet with high magnetic permeability, and the structure is drawn plate;
The magnetic circuit is short, the loss and noise level is low;
02) Winding adopts compression line, small loss, strong short-circuit resistance;
03) The active part adopts special pressing mode, and axial compression is reliable;
04) The oil tank is bell shaped, full folding plate structure, good appearance, easy maintenance;
05) The capsule type oil container is used to minimize the aging of oil.
06) Local discharge: the apparent discharge at 1.5 times the rated voltage is less than 80pC;
07) Noise :63MVA and below products less than 58dB(AN);
08) Power loss: no-load loss is 30% lower than IEC standard;
09) Reliability: No damage or oil leakage occurred to all in-service products;
10) Short circuit resistance: SFZ11-5000/132 products successfully passed the national short circuit resistance test
Transformer quality supervision and inspection center and through the Netherlands "KEMA" quality control system.
1)Simple maintenance: seldom need any maintenance.
2)They are pollution-free
3)They are used in the areas of contaminated and damped
4)They are easier to Install.
5)They have long servie life because of the dielectric heating & low thermal
6)Protects the property & people
7)For short circuit currents, they have high resistance
8)Performance is excellent
