Quality of QZY enameled copper round wire is guaranteed by the manufacturer's policy. This policy includes regular inspection and testing of the company's products. In accordance with IEC 60172:2004, the maximum rebound angle of the product must not be more than 5 deg. The elongation at break of the enameled wire shall not be less than the value of Table 4. Its nominal diameter shall not be greater than 0.100 mm.
The resistance of the enameled copper round wire shall be within the limits specified in Table 3 in all tests. The failure time at the lowest test temperature must be not less than 5000 h. The relevant product standards also define the straight weldability, thermal bonding, dielectric loss factor, and transformer oil resistance. Moreover, the material must pass the relevant heat-treating and annealing tests.
The copper wire must have a minimum diameter of 1.000 mm. The paint layer must not crack under any circumstances. It should meet the requirements of the relevant product standards. The maximum number of pinholes per 30 m enameled copper round wire should not exceed this limit. The conductor diameter should be 1.0 mm. The thickness of the film should be grade two and the failure time at the lowest temperature must not exceed 5000 h.
The minimum film thickness must correspond to the nominal diameter of the larger conductor. In other words, the minimum outer diameter must be 0.063 mm. The intermediate dimensions of the nominal diameter of the R40 series are also shown in Appendix A. The resistance of enameled copper round wire at 20 degC must be within the specified limits in Table 3. In addition, it is not necessary to measure the resistance at higher temperatures if the outer diameter is smaller than this.
In accordance with these standards, the resistance of the QZY enameled copper round wire
must comply with the specified limits in Table 3. For all other materials, the resistance of the enameled copper round wire must be within the limits in Appendix A. Its minimum film thickness should correspond to the nominal diameter of the larger conductor. The R40 series has intermediate dimensions of the nominal diameter of 0.063 mm.

The resistance of QZY enameled copper round wire is tested according to IEC 60172. The minimum required temperature for the insulation is 105degC. The resistance at 20degC shall be specified in Table 3. If the enameled copper round wire has a smaller nominal conductor diameter, it is used for applications involving high temperatures. Its thickness is grade 2 to avoid the possibility of corrosion.
Its nominal diameter should be 1.000 mm. The minimum film thickness should correspond to the diameter of the larger conductor. The minimum film thickness must be at least 0.1mm, which is the maximum permissible for a 0.63mm-diameter. However, it is not necessary to specify the resistance of a wire at higher temperatures. Its resistance at lower temperatures is higher than the resistance at higher temperature.
The QZY enameled copper round wire has a wide temperature range. Typical applications of this material include CATV coaxial cable, LAN and data cables. The high temperature and radiation resistance of this cable make it the perfect choice for these applications. It can be used for various electrical purposes, such as in electrical installations. The voltage rating is also important. The voltage of the copper round wire should be within a permissible range.
