With advanced design and manufacture technology, rational structure and advanced formation of material, strict and perfect test technology, dry-type transformer with thin insulation of casting resin has following features:
1. Hardly inflammable, hardly bursting, causing no pollution. Made with insulation material such as glass fiber and resin found in winding is hardly inflammable and causes no toxic gas.
2. Little partial discharge. Because of being poured under vacuum condition, no bubble and no cavity can be found in winding. High insulation level. The partial discharge of winding is less than 5pc.
3. High moisture-proof level. Not collecting dust. Against corrosive gas. The core passed antirust and preservative treatment can keep operation in bad circumstance, especially in hot and damp circumstances.
4. High mechanical strength. Good heat stability. The cylindrical hard winding excellent formed by insulation material, has the same thermal expansion coefficient as copper. So it has outstanding features against cracking and impact.
5. High insulation level. Good resistance against lightening impulse. High capacity of sustaining a sudden short circuit.
6. High capacity of overload because of high capacity of heat dissipation.
7. Low loss, small volume, light weight. These will make you reduce room and cost when installing.
8. High economic properties. Because of no fire and no explosion, it can be arranged in the center of load which is fully nearby the power transmission point. Thus, high cost of low voltage equipments will be saved.
Low loss, high capacity of overload and efficiency. Thus, expenses for electricity and installations can be saved a lot.
Without oil, a transformer and installations such as fireproofing, oil emission and oil collection are beyond consideration.
Not needing repair cost of material and maintenance will be reduced.
