Fiberglass covered copper wire or glassfiber wrapped cu conductor is a type of electrical conductor, which is insulated with a layer of fiber glass. This type of insulation provides a combination of electrical insulation and mechanical strength. And it is commonly used in various applications, including transformers, motors, and other electrical equipment where a combination of electrical insulation, thermal resistance, and mechanical strength is required. The specific requirements of the application will dictate the choice of insulation materials and construction.
Structure of Fiber Glass Covered Copper Wire
Fiberglass Insulation: The copper conductor is covered with a layer of fiberglass to provide electrical insulation. Fiberglass, also known as glass fiber, is a strong and durable material that offers good electrical insulating properties. It helps prevent short circuits and ensures the safe transmission of electrical currents.
Enamel Coating (Optional): In some cases, there might be an additional enamel coating on the copper conductor before the fiberglass insulation is applied. This enamel layer provides extra protection against environmental factors and helps improve the overall durability of the wire.
Copper Conductor: The core of the wire is made of copper, a highly conductive metal commonly used in electrical applications. Copper provides excellent electrical conductivity, making it suitable for transmitting electric signals efficiently.

Key features and advantages of Fiber Glass Covered Copper Wire
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.
