    Product Information

    This enameled flat wire takes high-quality oxygen-free copper or electrical aluminum rod as raw materials, which are strictly processed through drawing and extrusion by specification-specific molds to ensure uniform conductor structure. Its primary application lies in the windings of electrical equipment that demand stable operation at elevated temperatures, including heavy-duty transformers, high-frequency reactors, and industrial inverters. Based on the insulation paint formulation, it is categorized into six core types to match different thermal requirements:

    Frequently Asked Questions
    Q What conductor materials are available for the enameled flat wire?
    The enameled flat wire is available in two conductor materials: high-quality oxygen-free soft copper (complying with GB5584.2-2009) and soft aluminum (complying with GB5584.3-2009). Copper offers three mechanical strength grades (C1/C2/C3), while aluminum provides excellent electrical conductivity with resistivity โ‰ค 0.02801 ฮฉยทmmยฒ/m at 20โ„ƒ.
    Q What temperature grades are offered for the enameled flat wire?
    Six thermal grades are available: 120โ„ƒ (QQ/QQN), 130โ„ƒ (QZ), 155โ„ƒ (QZG), 180โ„ƒ (QZY), 200โ„ƒ (Q(ZY/XY)), and 220โ„ƒ (QXY). Each grade uses a specific insulation paint formulation to meet the thermal demands of different applications.
    Q What are the standard conductor dimensions for production?
    The conductor thickness (a) ranges from 0.80 mm to 5.60 mm, and the conductor width (b) ranges from 2.00 mm to 16.00 mm. The maximum width-to-thickness ratio supported is 20:1.
    Q Which international quality standards do these products comply with?
    All enameled flat wire products comply with GB/T 7095 series and IEC 60317 international standards. As an ISO9001:2015 certified manufacturer, Hengte Electric's products have also successfully passed SGS, UL, and CE certification tests.
    Q What breakdown voltage performance can be expected?
    At room temperature, the breakdown voltage reaches 1000V for Grade 1 insulation and 2000V for Grade 2 insulation. Insulation film thickness options range from thin film (0.06โ€“0.11 mm) to thick film (0.12โ€“0.17 mm), with self-adhesive layers from 0.03โ€“0.06 mm.
