The ordinary transformers winding inner and outer each turn of wire length with the difference of up to 3 times, so that with a large amount of lines, in addition to the cost of a large, and the resistance is also greater.Moreover, Toroidal Transformer's wire length with inner and outer is much less than ordinary one, makes a reduction of using the amount of coil wire, so that not only saves the copper, more importantly, but also reduce the transformer's resistance and improve the efficiency.To compare the Toroidal Transformer with the same power of ordinary transformer, the volume and weight can be reduced 25-30%, while the efficiency is up to 90% or more, (ordinary transformer usually about 80% ).Usage:1. Machine Tool Control: Tends to be used in the machine tool control circuits for power supply.2. Communication, Electronic Instruments, Meters: Ring Transformer due to big power, small size, anti-interference ability, widely used in high-end instruments, meters, communications equipment industry, a large area to replace the R- type and CD- type transformers.3. Medical Equipment: Beyond the Toroidal Transformer has a common transformer function, its anti-electric strength and resistance to damp heat capacity far higher than the national standards and industry standards.4. New Energy Areas: Widely used in solar energy, wind power generation system.5. Audio Equipment: Widely used in stage lighting audio, multimedia audio, professional amplifier and other audio devices.6. Electrical Control: 1. Current and voltage transformer 2. Buck Boost power supply 3. Automatic Control System7. Cable TV Network: 1. Amplifier 2. Modulators 3. Optical receiver 4. For the site billing system, etc.
