10A Enameled Copper Clad Aluminum Wire Class 130155 for motor transformer winding

Magnet wire is a metallic conductor insulated with a varnish and generally used for electrical applications. Most times it is wound in different shapes of coils to generate magnetic force for motors, transformers, magnets etc. Shenzhou cable produces over 30,000 different types of magnet wire with the most important differences of characteristics as follows:

Copper is the standard used conductor material with excellent conductivity and very good windability. For low weight and larger diameters Aluminum sometimes can be used. Because of the difficult contacting of Aluminum wire with problems of oxidation. Copper Clad Aluminum can help to compromise between Copper and Aluminum.

    Material composition

    Type Conductor material Insulation layer
    Copper clad aluminum enameled wire Aluminum core inside, copper layer outside Polyester, polyurethane and other paint layers
    Enameled aluminum wire Pure aluminum conductor Polyester, polyurethane and other paint layers
    Enameled copper wire Pure copper conductor Polyester, polyurethane and other paint layers

    Electrical performance

    Performance Indicators Copper clad aluminum enameled wire Enameled aluminum wire Enameled copper wire
    Electrical conductivity Between copper and aluminum (about 60%~70% of pure copper) About 61% of pure copper High electrical conductivity (approximately 100% IACS)
    DC resistance Lower than enameled aluminum wire, higher than enameled copper wire Maximum resistance (under the same cross-sectional area) Minimum resistance
    Current carrying capacity Better than enameled aluminum wire, slightly lower than enameled copper wire Minimum current carrying capacity Maximum current carrying capacity
    Skin Effect Copper layer improves high frequency performance, better than pure aluminum wire The current concentration surface is more obvious at high frequencies Best performance at high frequencies

    Mechanical and Physical Properties

    Characteristic

    Copper clad aluminum enameled wire

    Enameled aluminum wire

    Enameled copper wire

    Density

    About 2.7~3.0 g/cm³ (lower than copper, close to aluminum)

    2.7 g/cm³ (light)

    8.9 g/cm³ (weight)

    Flexibility

    Better than pure aluminum wire, close to copper wire

    Brittle, easy to break when bent

    Good flexibility, easy to process

    Antioxidant

    The copper layer can protect the aluminum core and has strong anti-oxidation ability

    Aluminum is easy to oxidize, so insulation protection needs to be strengthened

    Copper has good oxidation resistance

    Weldability

    Special process required (copper layer can be welded)

    High welding difficulty (aluminum easily forms oxide film)

    Excellent weldability

    Precautions for use USAGE NOTICE

    1. Please refer to the product introduction to select the appropriate product model and specification to avoid the failure to use due to the inconsistent characteristics.

    2. When receiving the goods, confirm the weight and whether the outer packing box is crushed, damaged, dented or deformed; In the process of handling, it should be handled with care to avoid vibration to make the cable fall down as a whole, resulting in no thread head, stuck wire and no smooth setting out.

    3. During storage, pay attention to protection, prevent from being bruised and crushed by metal and other hard objects, and prohibit mixed storage with organic solvent, strong acid or alkali. The unused products should be wrapped tightly and stored in the original package.

    4. The enameled wire should be stored in a ventilated warehouse away from dust (including metal dust). Direct sunlight is prohibited to avoid high temperature and humidity. The best storage environment is: temperature ≤50 ℃ and relative humidity ≤ 70%.

    5. When removing the enameled spool, hook the right index finger and middle finger to the upper end plate hole of the reel, and hold the lower end plate with the left hand. Do not touch the enameled wire directly with your hand.

    6. During the winding process, the spool should be put into the pay off cover as far as possible to avoid wire damage or solvent pollution; In the process of paying off, the winding tension should be adjusted according to the safety tension table, so as to avoid wire breakage or wire elongation caused by excessive tension, and at the same time, avoid wire contact with hard objects, resulting in paint film damage and poor short circuit.

    7. Pay attention to the concentration and amount of solvent (methanol and anhydrous ethanol are recommended) when bonding the solvent bonded self-adhesive line, and pay attention to the adjustment of the distance between the hot air pipe and the mold and the temperature when bonding the hot melt bonded self-adhesive line.
