SG (B) 10 H-class dry-type distribution transformers insulation
Overview : U.S. Dupont Nomex insulation material produced high - and low dry-type transformer winding with fire, Zixi, curing, heat release is good, low noise advantages of an in-depth load centres cases : high-rise buildings, airports, terminals, power plants, residential areas or packages of various places connected center. Normal conditions of use Level not exceeding 1000m indoor Highest temperature environment of the highest average temperature +30 +40 degrees centigrade +20 degrees, the highest average minimum temperature of -5 degrees testing According to user requirements to provide special conditions for use in the operation of the transformers Performance standards (light) B.GB/T10228-1997 dry-type electrical transformers technical requirements
Product models indicate
Performance characteristics 1, low voltage winding around a copper system cones style structure, the introduction of a winding-up structures, and vacuum Jinqi, heat Hongpei solidification to the winding-go round distribution balance leak magnetic small, high mechanical strength, heat release conditions are good, to resist short-circuit capability, low noise. 2, low noise cooling devices can be prescribed by the fans to start controlling devices and the closure of automatic control, thus making transformers 40% of operating capacity. 3, low voltage winding through mass assemblies and the temperature sensor system, according to a set value, the closure of air-compressors or warning, Tiaozha, played the role of the protection of transformers. 4, transformers for distribution 1P20 diameter, "the foreign matter does not enter Zhaoke 12mm, it also can prevent configuration 1P23 and vertical perspective into the water Linru =60 meridian east. Protective covering to effectively prevent small animals from entering the body, and the short circuit, power accidents, and protect personal security. |
