Product Introduction

Production Description

  FR4 Epoxy insulation rod is an excellent electrical equipment insulation material. It is composed of epoxy resin and fiberglass, and is processed by special technology, with characteristics of high strength, low density, high temperature resistance, corrosion resistance, etc. Compared with traditional insulation materials, epoxy insulation rods have higher mechanical strength and better insulation performance, which can prevent electrical equipment from failures and accidents caused by pollution, moisture, aging, and other reasons.


  G10 Epoxy rod, commonly known as pulling rod, is a rod with circular cross-section formed by hot pressing with molding die, which has high mechanical and dielectric properties. It is suitable for insulation structural components in motors and electrical equipment, and can be used in humid environments and transformer oil. It is generally used as a lightning arrester or insulator core rod. The requirements for epoxy rods as structural components in motors and electrical equipment are very different. According to their own insulation strength requirements, different epoxy rods can be selected to enable the demand side to choose the most suitable and reliable products.




  Epoxy insulation rod is a type of electrical insulation material that is widely used in the electrical and electronic fields. It is made of epoxy resin and fiberglass, and has good mechanical performance, chemical stability, and electrical insulation properties.
