Isolation Transformers

Yuebian Electric Co.,Ltd is one of the leading China isolation transformers manufacturers and suppliers, welcome to check 3 phase isolation transformers, KVA isolation transformers price with us. General: Three-phase isolation transformer in power system not only has the variable function, but also isolate the grid on the equipment of third harmonic, primary and secondary and copper foil shield, effectively protect the interference of harmonics on equipment. Especially suitable for import and export equipment, which is suitable for communication between 50 ~ 0.1KVA-1600KVA, the input and output voltage of 60HZ is not more than 1600V. Product input and output voltage (three-phase or multi input and output, etc.), the connection mode, adjust the tap position, winding capacity allocation, secondary winding, the box (according to different use environment choice), can be according to user's requirements for the design and manufacturing. Production feature: 1.The new high-quality cold-rolled orientation silicon steel laminations mounted; H - resistant temperature 180 DEG enameled wire, bare coil winding has the advantages of beautiful appearance, junior subordinated and duct fan heat fast, galvanized tripod by special paint dipping process, vacuum impregnation, drying in oven. It can effectively reduce the vibration and noise, increase the electrical strength, and adopt new technology, such as high temperature insulation material design, and the introduction of new technology, so that the transformer is more energy saving, more quiet. Energy saving low noise coil to keep the ventilation slot, air flow, rapid and effective to reduce the temperature of the coil.
