Class 105  Polyvinyl Acetal Round Enameled Aluminum Wire

Class 105 Polyvinyl Acetal Round Enameled Aluminum Wire is a durable and highly specialized round enameled aluminum wire, also known as PVF wire, and is highly regarded for its excellent resistance to transformer oil.

Conductor Part

The reason for using aluminum wire instead of copper wire as the conductor lies in cost and weight. In equipment such as large transformers and generators that are highly sensitive to cost and weight, the advantages of aluminum wire become particularly prominent.

Insulation Enamel Part (Polyvinyl Acetal)

The core value of Class 105 polyvinyl acetal enameled round aluminum wire largely stems from the polyvinyl acetal resin used in its insulation layer.

Common Specifications

Due to its excellent mechanical stability and transformer oil resistance, this wire is mainly used in oil-immersed transformers. Therefore, its common wire diameter range is 1 to 3.6 millimeters, corresponding to AWG 7 to AWG 18 or SWG 9 to SWG 19.

Application Analysis

1. Oil-Immersed Transformers

The most core and typical application scenario of Class 105 polyvinyl acetal enameled round aluminum wire is oil-immersed transformers. In such transformers, the windings are immersed in transformer insulating oil for a long time for cooling and insulation. Under such circumstances, the insulating material must have a certain degree of oil corrosion resistance. The excellent transformer oil resistance of polyvinyl acetal ensures that the insulation layer can exist stably for a long time without degrading due to oil erosion.

2. Low-Power Drive Motors

PVF enameled aluminum wire is suitable for motors with power ≤ 1kW, such as fan motors, washing machine motors, and power tool motors. Its mechanical stability can effectively resist daily vibrations, and the 105°C heat resistance class can meet the temperature rise requirements of such equipment.
