(1) Little flux leakage，the ring is very close，uniform magnetic circuit and
completely closed，no air gap in the magnetic circuit， therefore，particularly
small external magnetic flux leakage.
(2) Small losing，low-temperature，high efficiency
The magnetic induction B value transformer strength is in the design of about
1.7 T (saturation magnetic induction intensity up to 1.9 T ),less winding turns，
small internal resistance，thereby reducing the loss of copper and iron and
improve the efficiency of the transformer，winding Coil around the ring core，
so good heat dissipation, low temperature rise.
(3) Strong ability of overload
Winding due to the resistance of small, quick reaction, when the additional load
current suddenly increased,the toroidal transformers can quickly upgrade the
current to ensure the load needs. Especially in the HiFi stereo equipment，it is
very suitable to use this kind of toroidal transformer.
(4) Small size, light weight.
Winding transformer,not on the core framework,as long as packed insulation,or
with epoxy resin powder electrostatic spraying,you can direct routing, because
the magnetic induction intensity B value can be made higher, the size of small
core，Use less the copper，compare with the EI transformer can be reduced
about 30-40 percent.
(5) Low noise, no vibration
Because the iron sheet is very tight，no middle joints，electromagnetic are much
improved after the iron sheet heat treatment，the copper wire roll on the
insulating iron sheet ，no clearance in interior，so when working the noise is
low and no vibration .
(6) Good Technics
Free combination according the iron sheet size,no need mould fee,so it is high
universality of design the roll iron sheet is more simple than the EI，C，R，so
the cost is low .
