Introduction and uses of epoxy rods:
Epoxy rods are commonly known as pull-out rods. They are round-section rods formed by hot pressing with a forming mold. They have high mechanical and dielectric properties and are suitable for use as insulating structural parts in motors and electrical equipment. They can be used in humid environments and transformer oil. They are generally used for lightning arresters or insulator core rods.
1. As structural parts in motors and electrical appliances, epoxy rods have very different requirements. Different epoxy rods can be selected according to their own insulation strength requirements, so that the demander can better and more assuredly choose the right product!
2. Square bakelite rods are commonly known as pull-out rods. They are round-section rods formed by hot pressing with a forming mold. They have high mechanical and dielectric properties and are suitable for use as insulating structural parts in motors and electrical equipment. They can be used in humid environments and transformer oil. They are generally used for lightning arresters or insulator core rods.

16. Models and specifications can be customized according to needs.
17. Square rods can be processed by large cutting machines, and round rods can be processed by washing machines!
18. Reinforced insulating rods can better meet customer needs!
