Characteristics of structural

-

Core and the fuselage

Core dedicated core shear line processing, the new ladder joints to improve the flux toward the elimination of core at the seams, the local flux saturation, reducing the core loss of the empty CD, air cutting current, and reduce the transformer noise.

Core using the structure of the drawing board, the distribution of the number of pressure nail in order to increase the ability to withstand short circuit in the plate around, up and down the high-low-voltage support beam connection, make the core as a whole.In addition, the Core of surface coated silicon steel face plastic bonded together, so that after curing normalized core to become one, reducing intimate noise, increase the mechanical strength between the silicon steel plate and the piece, rust-proof core played an importanta good role.The lower body of the tank between the tank wall, high-intensity electrical laminated wood support, making parts of the body of the safe and reliable.

COIL:
High tension coil to continuous, low-voltage coil for continuous or spiral, a separate set of valve of the regulator line, the balance of ampere-turns, the mechanical force was reduced to a minimum. High and low voltage coil structure of the guide oil and oil flow city-oriented, full use of the flow of oil to take the heat.

Fuel Tank:

Tank is beautiful and simple, high mechanical strength. Finishing flange link, link key parts (such as casing, pressure valves, switches, etc.) to effectively prevent the leakage of oil, to prevent leakage.
