The enamel wire is a wire having an insulating layer, which is a transformation of electromagnetic energy in a winding form, also known as a winding wire.

Flat enameled wire is a type of enameled wire. It is a winding wire made of oxygen-free copper rods or electrical aluminum rods that are drawn, extruded or rolled by a certain specification die, and then coated with insulating paint for many times. The thickness is from 0.025mm To 2mm, the width is generally less than 5mm, and its aspect ratio ranges from 2:1 to 50:1. Flat enameled wire has a wide range of uses, especially in the windings of various electrical equipment such as telecommunication equipment, transformers, motors and generators.

1. Different materials: structure and composition are different
2. Different performance: Since the three-layer insulated wire cannot be directly welded, it needs to be stripped first, and the cost is higher, and it will be replaced by FIW; the insulation level is different, and the three-layer insulated wire can be produced with a temperature resistance of 200 degrees
3. Can be different in color, etc.

enameled aluminum wire is composed of aluminum conductor and insulation materials, which is insulated with a thin film or coating and creates a magnetic field when the wire is would in a coil and power is applied. Aluminum Conductor is main type of enameled wire.

Correspondence table of enameled wire diameter and resistance value
The resistivity of the copper wire ρ= 0.0172, the aluminum wire ρ = 0.0283, the wire resistance calculation formula:
R=ρ×L/S
(L = wire length, unit: meter, S = wire cross section, unit: mm^2)

The current mainly passes along the copper-clad aluminum wire on the surface of the wire, which is called the skin effect. The higher the frequency, the more obvious it is. The copper-clad aluminum wire uses this feature to save material. But its resistivity is slightly higher than that of pure copper wire, and the resistivity is also different with the thickness of the copper clad.

Copper Clad Aluminum Enameled Wire is one of magnet wire, used for electric equipment. ECCA is popular enameled wire, maybe instead of the copper enameled wire and aluminum magnet wire in some field.

For Aromatic polyimide tape-covered aluminum magnet wire, after the aluminum magnet wire is taped with a tape that is 1.5 mm thick with 1.0 mm of this thickness being polyimide film and the remaining 0.5 mm being fluoroplastic, it is heated and heat-sealed.

Question: During our production process, we found that one axis of enameled wire is wound around the axial inductance. This axis of enameled wire and other axis of enameled wire are wound on the same magnetic core. The inductance of the enameled wire with this axis is relatively high. We made 1mH inductance, and the enameled wire of the other axis was only 960uH, and the problematic wire of this axis was 1.025mH, and the inductance test frequency was 796kHz. (1) The number of stitches is the same as the number of turns, excluding the slip ring. (2) The 1-meter straight resistance is a bit smaller than that of other shafts. I personally think that the enameled wire contains magnetic substances, but if it contains magnetic substances, the resistivity should be greater, and the DC resistance should be greater. So please help to solve the problem, or have encountered this kind of problem before, please analyze it, thank you in advance!

Telephone cable is usually thought of only as a communication medium operating at a normal 48 Vdc level. But telephone cable is regularly used by telephone operating companies to supply power to remote telephony equipment such as: PCM (Pulse Code Modulation) repeaters, FDM (Frequency Division Modulation) repeaters, telegraph and various types of control circuits. The normal talk battery voltage is regularly exceeded in the case of long subscriber loops utilizing loop extenders and on dial long line circuits which operate in the 70 to 100 Vdc range. For these applications, the referenced devices are generally current limited to approximately 150 milliamps. In all such cases, normal telephone industry practice usually limits pair-toground applied voltage to 150 Vdc, and pair-to-pair voltage is usually limited to 300 Vdc.

Principle: Water molecule (HHO) decomposes water into oxygen and hydrogen through electrolysis. Hydrogen is combustible. Oxygen supports combustion. These two gases are ignited to form a hydrogen-oxygen flame. In layman’s terms, “water turns into fire”
