GTB Series Dry-type Transformer Tester
Dry type high-voltage test transformer test is one of the important projects of electrical equipment performance, it is widely used in power system, farmland, railway, oil field, substation, water plants, power plants and factories, colleges and scientific research units and pressure test chamber. The product test insulation strength, products insulation level, insulation defects in sample, measure a product's insulation withstand internal and external over-voltage capacity for all kinds of electrical equipment, electrical components, insulation materials.
This series of dry-type high voltage test transformer use advanced insulating materials and high-quality magnetic alloy material, epoxy resin vacuum casting and new technology of CD core. Compared with oil-immersed transformer, it has characteristics as moisture-proof, dust resistance, flame retardant, low loss, low noise; higher insulating strength, can withstand the impulse current without damaging the equipment capacity. The product has the advantages of small volume, light weight, handsome in appearance, stable performance, convenient carrying and the like, is currently upgrading new DC high voltage test transformer. The product passed test from the national high-voltage electrical measuring station center, and its performance meets the requirements of ZBK41006-89 standard.
