Copper & Aluminum Wire
Magnetically insulated winding wire for a wide variety of electrical devices that require the generation of electric and/or magnetic fields to perform electromechanical work. Examples of such equipment include electric motors, generators, transformers, actuator coils
Soft wire corrosion resistance is weaker, hard wire corrosion resistance is stronger; this is because the soft wire is a combination of multiple strands of fine copper wire, the total surface area of these copper wires must be much larger than a single strand of hard copper wire, and the larger the surface area, in contact with corrosive media, the rate of decay reaction is bound to be greater.
Copper stranded wire is commonly used in electrical equipment, widely used in electrical installations, switchgear, electric furnaces and batteries, etc., to play the role of electrical conductivity and grounding, so the quality of copper stranded wire is very important. The purchase of copper stranded wire needs to start observing from the appearance, generally good copper stranded wire its appearance is relatively bright, service has obvious damage and scratches, there will be no obvious oxidation reaction generated by the discoloration phenomenon. The outer edge of the color is more uniform, service has black spots, service has cracks, the distance is uniform and regular. Meet the above criteria is a good choice of copper stranded wire.
In order to protect the outer sheath of the cable from harm and reduce friction, the cable pulley is suspended on the steel strand. Its spacing is related to the weight of the cable unit length, generally installed every 2~3m distance, in order not to make the cable sag touch the ground as the principle, the cable pulley into a straight line installation. The wire mesh sheath is set at the end of the cable when used. When pulling the cable, the cable mesh sleeve and the wire rope must be installed between the anti-twist device.
Insulated wires also reduce interference and noise between wires and improve the quality and reliability of electrical signal transmission, thus ensuring the stability and safety of the power system.
Solderable polyesterimide enameled wire enamels are widely used on the magnet wire of relays, small transformers, small motors, contactors, ignition coils, solenoid coils and automotive coils.
High-power transformer wire enamel includes the following weight parts of raw materials: 50 parts of ethylene urea ethoxylate methacrylate, 28 parts of polyethylene glycol diacrylate, 8 parts of hydroxyethyl methacrylate, 4 parts of acid...
The potential and magnetic potential generated by the AC winding and the final electromagnetic performance are only related to the connected conductors, but not to the order of connection. In other words, as long as the conductors are connected in the same slot, it does not matter which one is connected first and which one is connected second, the final reflected electromagnetic performance is basically the same, only the ends are different, there may be slightly different end leakage resistance and DC resistance.
