Product Description

No-Encapsulated-Winding 11kv 33kv Dry Type Distribution Transformer


Feature

1. Good heat dissipating conditions, long heat aging period, extreme over-load capacity, capable of long-term 120% overload, without forced wind-cooling under IP45, capable of full-load operation for a long term.
2. Extremely high safety and anti-burning feature, lasting burning at a high temperature of 800ºC without emitting any smog.
3. Extremely strong heat resisting capability (be immediately full loaded at -50ºC).
4. 100% water-proof, excellent water repellency and moisture resistance.
5. Unique winding structure and intense field calculation, with scarce partial discharge.
6. Low loss with great energy-saving effect, no-load loss down by 10% on average and load loss down by 5% compared with SC9 series.
7. Insulation materials and copper wire can be easily recycled after life cycle without environment pollution.

Structural characteristics

1. Unique ceramic-insulating structure, the shape can be kept permanently with adoption of the insulated cylinder and high-frequency ceramic padding block of MORA company.
2. High and low windings are first processed with NOMEX insulation materials, then immersed in special-recipe H-level insulation materials for times through VPI vacuum pressure boosting equipment, next after many times of baking, sealed externally with high strength insulation materials, and solidified under high temperature, high-voltage windings adopt continuous structure of high mechanical strength and good heat dissipating conditions.
3. The iron core is made of layered imported high-quality highly-conductive magnetic silicon steel sheets and adopts stepping 45° wholly sliding structure. The coil and iron core are fixed with flexible devices so that the transformer is of low-level no-load loss and noise. The sureface of the iron core is processed with special technology. The iron core can be property clipped by a pull screw, with the upper and lower clips connected by a full plate and fixed together with the base and coil, and the coil being fixed by a flexible padding block. Thus the buffer structure can extenuate the coil, cviolation and reduce the noise.
4. The lead terminal is fixed at the upper part of the coil, with the tap at the middle of the coil. The low-voltage terminal is a conductive plate and adopts cold pressure welding.
