The temperature index test shall be carried out on IEC 60172 on unimpregnated enameled wire specimens with a nominal conductor diameter of 1.000 mm and a grade 2 film thickness. The temperature index shall not be less than the specified value of the relevant product standard, and the failure time at the lowest test temperature shall be not less than 5000h. See the relevant product standards for refrigerant resistance. Straight weldability can be found in the relevant product standards. Thermal bonding is subject to the requirements of the relevant product standards. See the relevant product standards for the dielectric loss factor. See the relevant product standards for transformer oil resistance. See the relevant product standards for weight loss. The pinhole test can be found in the relevant product standards.

For enameled wires with a nominal conductor diameter of 0.063 mm or more, the resistance value is not specified. When the conductor has a nominal diameter of 0.080 mm and above and 1.600 mm or less, the maximum rebound angle of the enameled wire shall not exceed the value specified in Table 5 when tested on a specified round bar with a specified load. The maximum rebound angle of the enameled wire with a nominal conductor diameter of 1.600 mm or more shall not exceed 5 °.

1. The temperature index test shall be carried out on the unimpregnated enameled wire specimen with a nominal diameter of 1.000 mm and a grade 2 film thickness in accordance with GB/T4074.7-2009. 2. The temperature index shall not be less than the specified value of the relevant product standard, and the failure time at the lowest test temperature shall be not less than 5000h. 3. When requested by the user, the manufacturer shall provide proof that the enameled wire meets the temperature index requirements. 4. Note: The temperature index for the extrapolated life of 20000h is only for unimpregnated enameled wire samples, not as part of the insulation system.

The preferred size of the nominal diameter of the conductor diameter conductor shall comply with the R20 number system in GB/T321-2005. 1. The temperature index test shall be carried out on the unimpregnated enameled wire specimen with a nominal diameter of 1.000 mm and a grade 2 film thickness in accordance with GB/T4074.7-2009. 2. The temperature index shall not be less than the specified value of the relevant product standard, and the failure time at the lowest test temperature shall be not less than 5000h. 3. When requested by the user, the manufacturer shall provide proof that the enameled wire meets the temperature index requirements. 4. Note: The temperature index for the extrapolated life of 20000h is only for unimpregnated enameled wire samples, not as part of the insulation system. The Celsius temperature relative to the temperature index is not the recommended enameled wire use temperature because the temperature of use is related to many factors, including the type of equipment involved. See the requirements of the relevant product standards for refrigerant resistance.  

See the relevant product standards for the dielectric loss factor. See the relevant product standards for transformer oil resistance. See the relevant product standards for weight loss. The pinhole test can be found in the relevant product standards. The type of packaging and packaging may affect certain properties of the enameled wire, such as resilience. Therefore, the type of packaging (such as the type of delivery reel) should be negotiated between the supplier and the purchaser to determine that the enameled wire should be wound evenly and tightly on the delivery reel or placed in the container. Unless there is agreement between the supplier and the buyer, there should be no more than one line of enameled wire in the delivery reel or container. When there is more than one line segment, the supplier and the buyer shall agree to mark the length of the line segment on the label and/or mark the package. When the enameled wire is delivered in a loop, the size and maximum weight of the loop shall be determined by the supplier and the buyer. Any additional protection on the coil GB/T610.1-2008/IEC603170-1:2005 It should be decided by both parties.
