BK(JBK) "Control transformer" is our company after many years to further absorb the advantages of similar products at home and abroad, the use of advanced technology and rigorous design for manufacturing, power can do 25VA-100KVA. Preferably foreign advanced method of terminal terminals, with excellent performance, reliable work, low energy consumption, small size, wiring safety, high protection level, wide application and other characteristics, can work for a long time under rated load, is an ideal voltage power supply.
The "single-phase isolation transformer" in the BEK series not only has the function of voltage change in the power grid, but also can isolate the third harmonics of the power grid to the equipment, and the establishment of a new neutral line point can remove the interference of the power grid Chinese mode and other neutral lines, because the output end of the single-phase isolation transformer is completely "disconnected" from the input end. This effectively plays a good filtering role on the input end of the transformer (power supply voltage supplied by the grid), thus providing a pure power supply voltage to the electrical equipment. (If additional shielding can be further exempted from the high-frequency pulse interference and noise caused by the transformer internal karma, the company can design and produce high-quality isolation transformers for customers)
Materials:
1. Iron core
The use of high-quality new cold to oriented high silicon silicon steel sheet stacked, adding silicon to the steel sheet can reduce the conductivity of the steel sheet, increase the positive rate, it can reduce eddy current, reduce its loss, the quality of the transformer used in the quality of the silicon steel sheet has a great relationship;
2. Wire
Using PEW, UEW, BIW, SEIW, FEAI light covered wire and glass wire, the transformer for the wire requirements are good conductivity, the coating layer has enough heat resistance, and to have a certain corrosion resistance, the most commonly used temperature grade F enameled wire.
3, insulation materials
The high temperature resistant insulating paper is used as the insulating material, with high temperature insulation, flame retardant and moisture resistance.
4. Terminal block
Small power using terminal block, beautiful appearance, excellent pressure, temperature resistance, flame retardant performance. High power adopts high quality copper bar.
5. Iron feet
Using CNC bending cold binding plate, there are colorful plating (golden), blue zinc (silver), zinc (ivory), surface anodized "black" and other environmental protection plating options.
