DRY TRANSFORMERS \u2013 GRAVITY LINE<\/h2><\/div>

Gravity Line products include various models and power classifications of cast resin transformers that can be used for a wide range of applications. The production range is up to 2500 kVA at voltages up to 36 kV. The Gravity Line uses efficient high-voltage coil winding technology to offer an affordable solution that does not compromise on the demands for high quality and performance maintained by SGB-SMIT Group standards.<\/p>\n

By keeping our engineering and development team in house, we are able not only to satisfy special customer requirements, but also to support the long-term development and evolution of the Gravity Line product line.<\/p>\n<\/div><\/div><\/div>

TECHNOLOGIES AND CERTIFICATES<\/h2><\/div>

The Gravity Line features excellent electrical, mechanical, and thermal properties while maintaining reliability, long-term sustainability, and environmental protection.<\/p>\n

The low-voltage windings are produced using aluminum foils, with prepreg or cast resin as insulation. The high-voltage windings are coiled from aluminum wires cast in epoxy resin under vacuum. All manufactured transformers undergo routine testing in our own testing laboratory followed by final quality checks.<\/p>\n

Gravity Line transformers are F1, C3, E3 certified and can be upgraded to higher climate or environmental classes if required. All transformers also pass partial discharge testing up to 5 pC. The insulation class of the transformers is F.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Advantages of Gravity Line dry-type transformers<\/h2><\/h2><\/div>

Gravity Line dry-type transformers feature not only fire safety, derived from flame-retardant materials and materials that do not produce toxic fumes in the event of a fire, as well as by increased short-circuit resilience. The transformers are also resistant to salinity and moisture.<\/p>\n<\/div>

Environmental consciousness<\/h3><\/h2><\/div>

Our transformers do not pose a risk to surface or ground water and there is no need for oil change or maintenance.<\/p>\n<\/div>

Cost-effectiveness<\/h3><\/h2><\/div>

A nearly maintenance-free solution provided under economically advantageous conditions, with long service life and simplified installation.<\/p>\n<\/div>
