(1) Little flux leakage，the ring is very close，uniform magnetic
completely closed，no air gap in the magnetic circuit，
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
small internal resistance，thereby reducing the loss of copper and
improve the efficiency of the transformer，winding Coil around the
so good heat dissipation, low temperature rise.
(3) Strong ability of overload
Winding due to the resistance of small, quick reaction, when the
current suddenly increased,the toroidal transformers can quickly
current to ensure the load needs. Especially in the HiFi stereo
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
with epoxy resin powder electrostatic spraying,you can direct
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
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
insulating iron sheet ，no clearance in interior，so when working the
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
the cost is low .
