Energy-saving product energy-eficient secondary-class oil-immersed transformer is our company through theresearch and application of new materials, new technology and the combination of independent innovation andtechnology introduction, through the optimization and innovative design of the core and coll structure, to reduce no-loadoss and noise The purpose of self-developed products.

Oil-immersed transformers offer many advantages. It has good heat dissipation performance and can effectively ensure the stable operation of the transformer; it has excellent insulation performance and high reliability; it is easy to adjust the voltage and can adapt to different electricity needs; and its technology is mature and its cost is relatively low.

Iron Core: The core is made of high permeability magnetic grain oriented cold rolled silicon steel sheet. The iron core is a new typeof iron core, and the ful obliaue iointed iron core has a core section of a multi-stepped step, and the iron voke and theiron core have equal sections.

Winding: The winding adopts corrugated oil passage, no immersion paint process, and the tightening belt is tied; the windingsare concentric coils: the high-voltage winding has taps corresponding to the tapping voltage requirements, and is led tothe tap changer, the switch is mounted on the box cover, and needs to be cut off. The tap voltage can be changed afterthe power supply.

Safety protection device: The 30-2000kVA transformer is equipped with a pressure relief valve;A gas relay with an alarm and trip terminal can be installed according to user requirements.

Oil temperature measuring device: The transformer is equipped with a tube holder of a glass thermometer, and the tube seat is arranged at the top of theoil tank and protrudes into the oil by 120±10 mm;The 1000-2000kVA transformer is equipped with an outdoor signal thermometer;
