Paper covered stranded wire is a type of conductor widely used in electrical equipment, particularly in power transformers and motors. Its structure consists of multiple fine wires twisted together, with one or more layers of insulating paper wrapped around the exterior to enhance its electrical insulation and mechanical strength.
The characteristics of paper-insulated stranded wire include:
1. Excellent Electrical Insulation: The insulating paper effectively prevents short circuits between wires, ensuring the safe operation of electrical equipment.
2. Good Flexibility: The stranded structure provides good flexibility, making it easy to install and arrange.
3. Enhanced Mechanical Strength: The combination of insulating paper and the stranded structure increases the mechanical strength of the wire, reducing damage from external impacts and vibrations.
4. Good Thermal Performance: The insulating paper can withstand high operating temperatures, making it suitable for use in high-temperature environments.
The main application areas of paper covered stranded wire include:
1. Power Transformers: Used in transformer windings to ensure stable power transmission.
2. Motors :Employed in the windings of stators and rotors to enhance the performance and lifespan of motors.
3. High-Voltage Electrical Equipment: Provides reliable insulation protection in equipment such as high-voltage switches and transformers.
