High Dielectric Strength PTFE Film Sheet For High Voltage Busbar Electrical Components

Product Name: PTFE Insulating Films

Overview:
PTFE insulating film makes full use of the outstanding characteristics of PTFE, such as its excellent voltage resistance, chemical stability, and high-temperature resistance. This film is an indispensable component in electrical systems, enhancing the safety and reliability of various electrical applications.

Key Features and Applications:

• Excellent Voltage Resistance: PTFE insulating film can withstand high voltages, providing reliable insulation in electrical equipment.
• Chemical Stability: It is highly resistant to chemicals, ensuring stable performance in diverse chemical environments.
• High-Temperature Resistance: The film maintains its properties at elevated temperatures, making it suitable for use in high-temperature electrical applications.
• Versatile Applications: PTFE insulating film is widely used in power stations, substations, transmission lines, and various electrical devices. It serves as capacitor media, wire insulation, electrical instrument insulation, sealing insulation sleeves, and high-voltage busbar insulation, ensuring the normal operation and safety of electrical systems.

Manufacturing Process:

• Film Extrusion: Produced through a precise extrusion process using high-quality PTFE resin. The resin is melted and extruded through a die to form a continuous film of the desired thickness.
• Biaxial Orientation (for directional films): For directional films, the extruded film undergoes a biaxial orientation process. This involves stretching the film in both the machine and transverse directions to improve its mechanical properties and dimensional stability.
• Sintering and Cooling: After orientation, the film is sintered at high temperatures to enhance its crystallinity and stability. It is then cooled under controlled conditions to prevent distortion.
• Slitting and Winding: The finished film is slit into the required widths and wound onto cores for easy handling and use.

Customization:
We recognize that different electrical applications have specific requirements. Therefore, we offer customization services for PTFE insulating film. Our team can produce films with different thicknesses, widths, and lengths according to customer specifications. We can also adjust the film's properties, such as its dielectric constant or thermal stability, by using modified PTFE resins or adding appropriate fillers.

Quality Assurance:
All our PTFE insulating films undergo strict quality control procedures. We start with high-quality PTFE raw materials and employ advanced manufacturing techniques to ensure consistent film quality. Each batch of film is inspected for thickness uniformity, surface quality, electrical properties, and mechanical properties. We also conduct performance tests under various environmental conditions to ensure the film's reliability and durability.
