The main performance indicators of seven insulating material

  Insulation material is to determine the motor, electrical equipment, reliability and service life of the key materials, the impact of its insulation of the main indicators are the following seven points:

  First, the degree of sealing

  On the oil, water quality isolation is better.

  Second, the insulation resistance and resistivity

  The resistance is the reciprocal of the conductance, and the resistivity is the resistance per unit volume. The smaller the conductivity of the material, the greater the resistance, the reciprocal relationship between the two, for the insulation material, always want the resistivity as high as possible.

  Third, the tensile strength

  Is the maximum tensile stress that the specimen is subjected to in the tensile test. It is the most widely used and tested test of the mechanical properties of insulating materials.

  Fourth, the resistance to burning

  Refers to the ability of the insulating material to prevent continued combustion when it is in contact with the flame. With the increasing use of insulating materials, its flammability requirements are more important, people through various means to improve and improve the resistance of insulating materials (even a special flame retardant paint, etc.). The higher the flame resistance, the better the safety.

  Fifth, resistant to arc

  Under the specified test conditions, the insulating material is resistant to the arc acting along its surface. Test the use of high voltage AC current, by high pressure between the two electrodes generated by the arc, so that the surface of the insulating material to form the conductive layer of the time required to determine the arc resistance of insulating materials. The greater the time value, the better the arc resistance. Arc resistance in particular for a variety of insulating paper has a better description;

  Sixth, relative dielectric constant and dielectric loss tangent

  Insulation material uses two: electrical network components of the mutual insulation and capacitor media (energy storage). The former requires a relatively small relative dielectric constant, which requires a relatively large relative dielectric constant, and both require dielectric loss tangent, especially in high frequency and high voltage applications of insulating materials, in order to make dielectric loss is small, are required to use Dielectric loss tangent small insulation material.

  Seventh, breakdown voltage and electrical strength

  In a strong electric field under the destruction of insulating materials, loss of insulation into a conductive state, known as breakdown. The breakdown voltage is called the breakdown voltage (dielectric strength). Electrical strength is under the conditions of the breakdown of the voltage and withstand the voltage between the two electrodes of the business, that is, the unit thickness of the breakdown voltage. For insulating materials, the general breakdown voltage, electrical strength of the value of the higher the better.

  According to the needs of different parts, many types of insulation materials, many different insulating paint, insulating paper, insulation tube and even tie belt with different performance indicators can be concerned about the matter.
