The purpose of such isolation transformers is to provide electrical isolation between the load and the power supply, prevent electric shock in the IT distribution system so as to protect the insulation of the device connected from being damaged, and provide neutral point connection for isolation or grounding. Through the shielding between the primary and secondary levels and the static electricity connected as well as reinforced insulation, this type of isolation transformer can provide isolation for sensitive loads to prevent the power supply system from severe atmospheric interference. In addition, the iron core has the characteristics of high high-frequency loss, thereby suppressing high-frequency clutter from entering the control loop.
Our company has been using high-quality materials and advanced process technology to professionally produce single/three-phase dry-type isolation transformers between 160VA and 800KVA for many years. The products are developed with reference to the latest foreign similar products for imported equipment, and are widely used in various power supply occasions with AC 50/60HZ and input and output voltages not exceeding 1000V. Various inputs and outputs, voltage levels, connection groups, tap adjustment positions, winding capacity allocation, secondary winding configuration, whether to equip with a shell, etc., are carefully designed and manufactured according to user requirements. This series of isolation transformers are widely used in power transmission and distribution of subways, high-rise buildings, locomotives, elevators, stations, printing, machine tools, docks, industrial and mining enterprises and tunnels, as well as the use of imported equipment.
