    non-encapsulated coil power transformer

    nProduct features

    1. The well-designedcoil structure and vacuum impregnation treatment process makes SG (B) 10transformer free of partial discharge and free of fracturing or insulationlevel decline during the whole shelf life.

    2. Continuouswinding, low-voltage foil burning, overall vacuum impregnation and curingprocess, as well as support of high-strength ceramics are adopted for highvoltage, which has good bearing capacity for sudden short-circuit current.

    3. Nonflammable,flame retarded, nontoxic, self-extinguishing, fireproofing.

    4. SG (B) 10transformer almost produces zero smoke under high temperature and flamingconditions.

    5. The transformeris of Class H (180) insulation.

    6. The insulationlayer is very thin and uniform. The short-term overload capacity is strong,forced cooling is unnecessary, 120% of long-term overload, and 140% ofoverload for 3 hours are possible. Since such insulating material is ofanti-aging and flexible, full load immediately is possible under thecondition of ±50.

    nService conditions

    1. Ambienttemperature: -50 - +50
    2. Altitude1000m.
    3. Users shallprocess together with the Technical Department through negotiation for othercontents beyond those specified in the technical condition, and indicateduring ordering.

    nProduct overview

    It adopts non-encapsulatedcoil three-phase dry-type power transformer produced by NOMEX insulationsystem approved by United States UL, which characterized by safety,reliability, energy saving, fire protection, anti-explosion, simplemaintenance and so on. It boasts advances design, reasonable structure,good-looking appearance and main performance indexes which are superior tonational standard, such as partial discharge level, no-load loss, load loss,noise and adaption to high-humidity atmosphere.

    It can be installed in dirtywet environment near lake, sea, river and in area with high fire protectionrequirements and large load, suitable for high-rise building, airport,station, wharf, metro, hospital, power plant, metallurgical industry,shopping center, residential concentration area and petroleum chemicalindustry, nuclear power plant, nuclear submarine and other places.
