Characteristics And Application Of Copper Clad Aluminum Enameled Wire

Heat resistance refers to the properties of a substance that can maintain its excellent physical and mechanical properties under heated conditions. The highest use temperature of commonly used materials to characterize. There are different standards and test methods for different materials. Such as plastics are generally expressed by Martin heat-resistant temperature. The coating industry uses a blast constant temperature oven or a high temperature furnace. After it reaches the specified temperature and time, the surface condition of the paint film is inspected, tested, or other properties such as impact, bending, water immersion, salt spray test, etc., and then before and after Test data representation. All coatings used in higher temperature occasions must use heat resistance as an important technical indicator of the coating film

Heat Level 180C Fiberglass Covered Copper Magnet Wire
Performance advantages: It has the characteristics of good voltage breakdown resistance and high mechanical strength of the insulating layer.
Product use: Mainly used for AC motors as windings.

The main advantage of the TIW wires is relatively high electric strength of the insulation, with breakdown voltage min. 6kV. Obtaining such a high resistance was possible by the use of a reinforced, three-layer conductor insulation. Third external insulation made of polyamide gives excellent flexibility and high mechanical resistance of the wire. Normally, TIW wires are produced in thermal class B. Fully automated manufacturing process provides a central position of conductor and the same thickness of insulation at any point of the wire.

Poor soldering is mainly manifested in that the paint film after soldering will not melt off after the soldering, which causes the phenomenon of poor soldering.

In the long-term thermal aging test, three or more temperature points are usually selected for accelerated aging, commonly known as “three-point aging”.

The samples for the aging test are stranded enameled wire pairs. The production of the stranded pairs should meet the requirements of ASTM D2307 or NEMA 1000 standards, including the weight to be applied when making the stranded pairs, the number of twisted turns, the effective length of the stranded area, and The length of the two ends of the twisted pair, etc. When making a twisted pair, the required force and the number of twist turns will vary depending on the diameter of the wire. The effective length of the stranded area has nothing to do with the wire diameter, the effective length is 121¡À6 mm, and the two ends are at least 50 mm long. At least 10 twisted pairs per temperature point and mounted on twisted pair racks for high temperature aging test.

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.

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.

Enameled wire is a type of electromagnetic wire, usually refers to the insulation wire used to make coil or winding in electrical products. It is also called the winding wire.
The electromagnetic wire must meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, working at high temperature in short and long time, as well as the strong vibration and centrifugal force under high speed on certain occasions, resistance to corona and breakdown under high voltage, and chemical corrosion resistance in special atmospheres, and the requirements for tensile, bending and wear, as well as the requirements of drawing, bending and wear during winding and inlaying. Swelling and erosion during immersion and drying.

1. Cutting
The enameled wire is composed of a conductor and an insulator, and the hardness of the two parts is very soft, so it can be cut by using a TabCUT-200 precision cutting machine with a general SiC cutting chip. Since the insulator is coated on the conductor, and its hardness and ductility are quite different, and the insulating layer has a certain degree of peeling, it is better to use some soft materials such as tin foil, rubber, etc. to wrap the cutting part when cutting. Up to prevent the insulation layer at the fracture from peeling off after cutting.

Generally speaking, UL certified enameled wire needs to do four tests:
Thermal Aging Test (Full Thermal Aging Test or One Temperature Thermal Aging Test)
Dielectric Strength Test
Elongation and Heat Shock Test
Infrared Analysis – IR
