Fiberglass cladding provides excellent insulating properties that effectively isolate the current between the conducting parts and the external environment, preventing leakage and arcing faults. This insulating layer usually consists of glass fibers and their coated insulating varnish, which can withstand higher voltages.

Fiberglass copper enameled wire is able to withstand high temperatures and usually has good thermal stability. This makes it suitable for use in high-temperature environments in confined motors, such as ovens, heaters and other high-temperature equipment. The fiberglass cladding prevents the wire from softening, melting, or losing insulating properties at high temperatures.

Fiberglass copper enameled wire has good corrosion resistance against some chemicals and wet environments. This makes it perform well in some special environments, such as chemical equipment, wet environments or places with corrosive gases.


The fiberglass cladding also gives the wire high mechanical strength, making it resistant to external forces such as stretching, bending and extrusion. This is important in vibration environments where complex wiring and high-speed rotating parts are found inside motors, helping to maintain the integrity and reliability of the wire.

The mechanical strength and flexibility of fiberglass copper enameled wire allows it to withstand the vibrations and shocks of motor operation, reducing the risk of wire breakage and abrasion.

The insulation of fiberglass copper enameled wire is typically coated with a high-temperature insulating varnish. High-temperature enamels are insulating materials that remain stable in high-temperature environments. When cured, the varnish forms a strong insulating layer that provides additional insulation protection, allowing the wire to be operated for long periods of time at high temperatures without damage.

Fiberglass copper enameled wire is a reliable choice in hermetically sealed motors, providing good insulation, high temperature resistance, corrosion resistance and mechanical strength for motor systems in a variety of industrial and commercial applications. However, specific wire selection should be evaluated and chosen based on the motor's design requirements, operating environment and electrical standards.
