Main Indicators Affecting the Performance of Insulation Polyester Fiberglass Dog Bone

The main indicators affecting the performance of polyester fiberglass dog bone, is a kind of electrical insulation materials:
1.Insulation resistance and resistivity of polyester fiberglass dog bone:
Resistance is the inverse of conductance, and resistivity is the resistance per unit volume. The less conductive a material is, the greater its resistance is, and the two have an inverse relationship. For insulating materials, it is always desirable that the resistivity be as high as possible.
2.Positive dielectric constant and dielectric loss tangent of polyester fiberglass dog bone:
Insulation materials are used for two purposes: the mutual insulation of each part of the electrical network and the capacitor’s dielectric (energy storage). The former requires a small relative dielectric constant, the latter requires a large relative dielectric constant, and both require a small dielectric loss tangent, especially for insulating materials applied at high frequencies and high voltages. Insulation material with small dielectric loss tangent.

3.The breakdown voltage and electrical strength of polyester fiberglass dog bone:
In a certain strong electric field, the insulation material is damaged, and the insulation performance is lost and it becomes a conductive state, which is called breakdown. The voltage at breakdown is called the breakdown voltage (dielectric strength). The electrical strength is the quotient of the voltage between the voltage when the breakdown occurs and the two electrodes withstand the applied voltage, that is, the breakdown voltage withstood by the unit thickness. In general, the higher the breakdown voltage and electrical strength of an insulating material, the better.
4, Tensile strength of polyester fiberglass dog bone:
It is the maximum tensile stress that the specimen is subjected to during the tensile test. It is the most widely used and representative test of the mechanical properties of insulating materials.
5.Fire resistance of polyester fiberglass dog bone:
Refers to the ability of an insulating material to resist combustion when it comes in contact with the flame or to prevent it from continuing to burn when it leaves the flame. With the increasing application of insulating materials, the requirements for their flame resistance are more important. People have improved and improved the flame resistance of insulating materials through various means. The higher the flame resistance, the better its safety.

6, Arc resistance of polyester fiberglass dog bone:
The ability of an insulating material to withstand arcing along its surface under specified test conditions. During the test, an alternating high voltage and small current are used to judge the arc resistance of the insulating material by the time required for the conductive layer to form on the surface of the insulating material by the arcing effect between the two electrodes. The larger the time value, the better the arc resistance.
7, Tightness of polyester fiberglass dog bone:
It is better to seal and isolate oil and water.
