Relationship Between Electrical Conductivity and Insulation of Insulating Material Insulation Board
Sealing degree of insulating material (insulation board): Sealing isolation of oil quality and water quality is the best. Insulating material resistance to combustion: refers to the ability of an insulating material to resist burning when it contacts the flame or when it leaves the flame. As the application of insulating materials continues to expand, the requirements for its resistance to combustion are more important and the requirements are getting higher and higher. ZTELEC’s scientific research personnel and technicians have passed various tests to improve and improve the flame resistance of insulating materials. The higher the resistance to combustion, the better its safety.
Insulation material (insulation board) relative dielectric constant and dielectric loss tangent: Insulation material has two uses: the mutual insulation of the components of the electrical network and the medium of the capacitor (storage energy). The former requires a relatively small dielectric constant, the latter requires a relatively large dielectric constant, and both require a small dielectric loss tangent, especially for insulating materials applied at high frequencies and high voltages. Insulation material with a small dielectric loss tangent.
Tensile strength of insulating material: The tensile force of the maximum tensile force that the specimen is subjected to in the tensile test of the insulating material. It is the most widely used, most common and representative test for the mechanical properties of insulating materials. The electrical resistance of an insulating material is the reciprocal of conductance, which is the electrical resistance per unit volume. The smaller the conductivity of the material, the greater the resistance, and the reciprocal relationship between the two. For the insulating film, it is always desirable to have the resistivity as high as possible.
