Performance levels and classifications of insulation materials
Insulating materials in an electric field will break down when the electric field intensity increases to a certain limit. The electric field strength of this insulation breakdown is called insulation withstand voltage strength (also known as dielectric strength or insulation strength), which is usually expressed in terms of the voltage KV value that a 1mm thick insulating material can withstand.

Insulating materials are absolutely non-conductive materials?
Insulating materials are materials used to isolate conductive parts of different potentials. Its conductivity is approximately below 10-10 West/meter. The insulating materials mentioned in this article are electrical insulating materials. According to the national standard GB2900.5, the definition of insulating materials is: "materials used to electrically insulate devices."

Insulating material properties
1. Combustion resistance refers to the ability of insulating materials to resist burning when in contact with flames or to prevent continued burning when away from flames. With the increasing application of insulating materials, the requirements for their combustion resistance are becoming more important. People use various means to improve and enhance the combustion resistance of insulating materials. The higher the combustion resistance, the better its safety.
