18 uses of epoxy glass fiber rod

Epoxy glass fiber rods are also commonly known as pull rods. The rods with circular cross-sections formed by hot pressing of forming molds have high mechanical and dielectric properties and are suitable for insulating structures in motors and electrical equipment. Components, and can be used in humid environments and transformer oil; generally used for lightning arresters or insulator core rods.

1. Epoxy glass fiber rods are used as structural parts in motors and electrical appliances, and their requirements are very different. According to their own insulation strength requirements, different epoxy glass fiber rods can be selected to make the demander better and more assured Choose a suitable product!

2. Square bakelite rods are commonly known as pull rods. The rods with round cross-sections formed by hot pressing of forming molds have high mechanical and dielectric properties and are suitable for insulating structures in motors and electrical equipment. Components, and can be used in humid environments and transformer oil; generally used for lightning arresters or insulator core rods.
