Different Enameled Have Different Characteristics

For the electromechanical installation industry, wire and cable occupy an important position in the electromechanical installation engineering. As the main raw material, copper accounts for 70%~80% of the total cost of cable products. The price of copper cables has increased sharply with the increase of copper prices. The investment and construction parties have brought great difficulties in engineering cost control. For this reason, the research and application of copper- Enameled Aluminum Wire and Enameled Copper Wire have grown rapidly.

Acetal enameled wire with thermal grades of 105 and 120, good mechanical strength, adhesion, resistance to transformer oil and refrigerant resistance, but the product has poor moisture resistance, low thermal softening breakdown temperature, and durable benzene-alcohol mixed solvent. Defects such as weak performance, only a small amount for the oil-immersed transformer, the winding of the oil-filled motor.

The Magnet_wire of polyester and modified polyester, the ordinary polyester enameled wire has a heat rating of 130, and the modified enameled wire has a thermal rating of 155. The product has high mechanical strength, good elasticity, adhesion, electrical function and solvent resistance. The weak point is that the thermal shock resistance is poor and the moisture resistance is low. It is the largest variety of production in China, accounting for about two-thirds. It is widely used in various motors, electrical appliances, instruments, telecommunications equipment and home appliances.

Polyurethane enameled wire; heat grade is 130, 155, 180, 200. The biggest feature is that it has straight solderability, high frequency resistance, good coloring, and good moisture resistance. It is widely used in electronic appliances and precision instruments, telecommunications, and meters. The weakness of this product is that the mechanical strength is slightly poor and the heat resistance is not high. Moreover, the flexibility and adhesion of the large-size lines are poor, so the specifications for the production of this product are small and medium-sized.
