Glass-fiber-covered rectangular wire is a flat winding wire with multiple layers of heat-resistant glass fiber wrapped around the conductor. It uses copper (or aluminum) as the conductor, with the surface evenly wrapped with glass fiber and treated with a special heat-resistant varnish or paint-free finish. This gives it excellent electrical insulation properties while also being resistant to high temperatures and mechanical wear, making it suitable for long-term operation in harsh environments.
Construction:
Conductor: High-purity oxygen-free copper or electrical aluminum, offering excellent conductivity.
Insulation: Multiple layers of evenly wound glass yarn, with varying thickness and material available upon request.
Impregnation: Optional heat-resistant varnish impregnation or heat setting treatment enhances wear and moisture resistance.
Product Features:
Strong High-Temperature Resistance: The glass fiber itself is extremely heat-resistant, and combined with the high-temperature resistant paint, it can operate for extended periods in environments exceeding 200°C.
Excellent Insulation: The composite insulation structure formed by multiple layers of glass fiber and paint offers high breakdown strength, making it suitable for high-voltage equipment.
Mechanical Strength: The cured insulation layer is tough and wear-resistant, capable of withstanding significant tensile and compressive stresses, as well as mechanical shock.
Dimensional Stability: Resists deformation due to heat or moisture, ensuring long-term stable winding operation.
Environmentally Friendly and Corrosion-Resistant: Both the glass fiber and the insulating paint are chemically resistant, making them suitable for a variety of complex operating conditions.
Applications:
High-voltage transformers: Used to manufacture high-voltage windings, improving heat resistance and insulation.
Traction motors: Meet the insulation requirements for long-term, high-load operation.
Wind turbine generators: Resistant to high-frequency vibration, moisture, and high temperatures, suitable for complex outdoor environments.
Reactors and induction heating equipment: Maintain stable performance under high-temperature and high-voltage conditions.
Glass fiber-covered rectangular wire, with its excellent heat resistance, mechanical resistance, and insulation properties, plays a vital role in industrial motors and high-temperature equipment. With the development of high-end equipment manufacturing, its application scope will become more extensive, and the requirements for performance and reliability will continue to increase.
