Performance characteristics
45° full oblique stepping seam core
The iron core is made of imported cold-rolled silicon steel sheets
with high magnetic permeability and good grain orientation, 45o
full oblique stepping joints, special square tube pull plate
structure, and the core column is tied with insulating tape; the
surface is coated with special resin to prevent moisture Rust
effectively reduces the no-load loss, no-load current and iron core
noise.
Multilayer segmented cylindrical high voltage coil
The high-voltage winding conductor is wound with F-class insulated
copper wire, with long and short cut glass fiber mat as reinforcing
filler, and is cast with epoxy resin mixture in a vacuum state
(1-3mbar). Effectively suppress the occurrence of partial discharge
phenomenon, and the amount of partial discharge does not exceed
5PC.
Longitudinal airway foil structure low voltage coil
The low voltage coil is wound on an automatic foil winding machine
with good quality foil conductors, argon arc welding, and high
welding accuracy; prepreg DMD is used as interlayer insulation, the
inner and outer parts are insulated by prepreg glass cloth, and the
upper and lower ends are sealed with epoxy resin Die and then
Enter the curing oven to solidify as a whole, with good
moisture-proof performance;
Robust and beautiful protective shell
IP20 can prevent solids with a diameter greater than 12mm from
entering, and can resist accidental impact; IP23 not only has the
function of IP20, but also prevents the inflow of water droplets
within a 60o angle to the vertical. It is suitable for outdoor
installation and use; it can be customized.
Perfect temperature protection control device
The overheating protection device mainly realizes the temperature
detection and control of the transformer through the PT thermistor
embedded in the low-voltage coil. Circuit display of three-phase
winding temperature value during transformer operation
