Electrical Insulation: The primary purpose of the fiberglass insulation is to provide electrical insulation, preventing the copper wire from coming into direct contact with other conductive materials or surfaces. This helps to avoid short circuits and ensures the safe and efficient operation of electrical devices.
Thermal Resistance: Fiberglass is known for its thermal resistance properties. The insulation can withstand high temperatures, making it suitable for applications where heat is a consideration. This feature is particularly important in environments where electrical components may experience elevated temperatures.
Mechanical Strength: The fiberglass layer adds mechanical strength to the wire, making it more robust and durable. This mechanical strength can help the wire withstand bending, flexing, and other mechanical stresses that may occur during installation and use.
Chemical Resistance: Fiberglass insulation is resistant to many chemicals, which can enhance the wire' s resistance to environmental factors. This makes it suitable for applications where exposure to chemicals or corrosive substances is a concern.
Resistance to Moisture: Fiberglass is generally resistant to moisture, adding a level of protection against the effects of water and humidity. This is beneficial in preventing corrosion of the copper core and maintaining the electrical performance of the wire.
Fire Resistance: Fiberglass is inherently fire-resistant, and this property adds a level of fire protection to the wire. In applications where fire safety is critical, such as in certain industrial settings, the use of fiber glass-covered copper wire can be advantageous.
Flexibility: Despite the added mechanical strength, fiber glass-covered copper wire can still maintain flexibility, allowing for ease of handling and installation.
Dielectric Strength: Fiberglass has good dielectric properties, meaning it can withstand high electric field strengths without breaking down. This contributes to the overall electrical performance and reliability of the wire.
Manufacturing Process
Application Scope of Glass Fiber Wrapped Wire
Medical
Accurate and reliable light delivery is vital during minimally invasive surgery. Pure white, homogeneous light in visible wavelengths offers intense illumination with a very natural color impression. This light is delivered via multi- component glass optical fibers that maintain high transmission over long distances to provide a true-to-life view of human tissue.
By using fiber optic image guides,images from inside the body can be transferred to a screen to give the surgeon a complete picture of the area of treatment.
Industrial applications
Fiber optic glass cables play a crucial role in industrial applications by carrying light from a source to a measurement device or from an object under scrutiny to a detector. Whether guiding light and images around a corner, out of a tight space,or away from a hot, dark, or challenging area,fiber optics are critical for many of the world's most advanced technologies, essential for semiconductor manufacturing,industrial automation, control systems, and quality monitoring.
Defense and security
In defense, glass fiber optic cables are used for situational awareness and advanced sensor systems. As glass is passive,it can be used without power in degraded mode. Fiber optic glass solutions are used for night vision and information transfer, for turbine and fuel monitoring as well as for remote engine monitoring in hostile environments.
Automotive
Side-emitting glass optical fibers are used in the automotive industry to generate bright, clear, colorful and uniform contour illumination throughout a car's interior. In exterior applications, they can create outstanding light effects for contour or accent illumination, even in harsh conditions
Aviation
In the aviation industry, fiber optic lighting solutions are used for seats, cabins and monuments. The individual light designs do not only represent the airlines' brand, but even more importantly, they contribute to crew and passenger comfort and well being during a flight.
Fiber optic communication
Glass optical fibers based on silica are foundational to modern communication networks due to their ability to transmit large amounts of data rapidly and reliably over long distances.
Glass Fiber Wrapped Wire: Comparison of Common Conductor Materials
Copper Conductor
Excellent conductivity and high mechanical strength, it is currently the most widely used type. Copper conductors exhibit less skin effect at high frequencies, making them suitable for high-frequency applications such as variable frequency motors.
Aluminum Conductor
Cost is 30%~40% lower than copper conductors, and it is about 60% lighter, but its conductivity is only about 60% of that of copper. Aluminum conductors are suitable for cost-sensitive, continuously operating transformer and reactor products.
