Description:Features and advantages: SG(B)10 series non-encapsulated dry-type transformers introduce the US Dupont Reliatran technology and adopt Dupont NOMEX paper based insulation system, which is safe and reliable, environmentally friendly, energy saving, fireproof and blastproof, insensitive to humidity dust and pollution, and of great surge capacity, small dimension and easy maintenance. 1) Safe: a) High level of safety, grade-H insulation class, fire-resistant, non-combustion-supporting, self-extinguishing, free from toxic gas, good fire protecting performance b) Free from partial discharge and fissuration in service. The insulation system of the winding is impregnated with solvent less insulation varnish time and again by VPI vacuum pressure equipment and solidified through high temperature baking, therefore it is dampproof, antifouling, dustproof, has intense thermal shock bearing ability, and is free from partial discharge and fissuration c) Small volume and light weight. The transformer adopts Dupont NOMEX paper as main insulating material and as insulating system of its most heated point 2) Relievable: a) Great surge capacity and excellent short circuit bearing ability due to its new design, new material, new techniques, and good heat radiation effect. It can run safely under 120% over loading for long time b) Dupont NOMEX paper based insulation system enables the transformer to maintain excellent electrical performance and mechanical property in its whole service life.
