Non-Sealed H-Grade Insulated 3-Phase Dry Type Power Transformer

Basic Info

Model No.:  SG(B)10

Product Description

Model NO.: SG(B)10 Phase: Three Cooling Method: Dry-type Transformer Certification: ISO9001 Frequency Characteristics: High Frequency Cooling: Dry Type Model 2: Sgb10-250/10 Trademark: Onegreen Origin: Xi′an Shaanxi Application: Power Coil: Core-type Transformer Winding Type: Multi-winding Transformer Usage: Power Transformer Shape of Coil: Ring Model 1: Sg10-100/10 with IP 20 Enclosure Model 3: Sgb10-2500/10 Specification: SGS HS Code: 850431900 H Class Insulation Non-sealed Windings Dry Type Transformers

H class insulation non-sealed windings dry type transformers, which are made of NOMEX insulated materials certificated by UL in USA. This type transformer is safe, reliable, energy-saving, fireproof, flameproof, and easy maintenance. Besides, it also has advantages such as advanced design, reasonable structure, and good aesthetic. Its main technical performance index is superior to National standard, such as partial discharge, no-load loss, load loss, noise and operating at humidity circumstance. It is suitable for regions with special requirements including dirty, wet surroundings near lake, river, sea, heavy-load region, and skyscrapers, airports, railway stations, wharfs, subway, hospitals, power stations, shopping centers, residential dense district, petrochemical, nuclear power stations, and nuclear powered submarines.

Non-Sealed H-Grade Insulated 3-Phase Dry Type Power Transformer


1 Due to elaborate design for the windings and vacuum pressure immersion treatment, which can ensure SGB 10 transformers minimum partial discharge(¡ 5pc)¬ Without any chaps and reduction of insulation level during whole service life.
2 The HV winding is continuous structure. The LV winding is foil structure. Use vacuum pressure immersion and high temperature solidifying treatment and adopt the high strength biphenyl aether material or ceramic as support. So it has well insulation performance and short-circuit withstand ability.
3 Difficult to flame, flameproof, innocuous, non-pollution, self-extinguishing, fireproofs.
4 Even if burning under high temperature, SGB 10 transformers seldom bring any smoke.
5 Hermo-tolerance class of insulation: H (180¡ æ ).
6 Insulation layer is very thin and equality, it has extremely over-load ability in short duration, and it is not necessary to force air cooling, it allows 120% over-load for long duration and 140% over-load for 3 hours. Due to anti-aging insulation material with bound, so it can reach full-load at ¡ 50¡ æ Condition.
