Product Details
PP insulation sheet resistance and resistivity: Resistance is the reciprocal of conductance, and resistivity is the resistance per unit volume. The smaller the electrical conductivity of the material, the greater its resistance. The two are in a reciprocal relationship. For PP insulating sheet materials, it is always desirable to have the highest resistivity as possible.
PP insulating sheet manufacturers analyze, relative permittivity and dielectric loss tangent: PP insulating sheet material has two uses: the mutual PP insulating sheet of each part of the electrical network and the medium of the capacitor (energy storage). The former requires a small relative permittivity, the latter requires a large relative permittivity, and both require a small dielectric loss tangent, especially for PP insulating sheet materials used under high frequency and high voltage, in order to make the dielectric loss small, both A PP insulating sheet with a small dielectric loss tangent is required.
Breakdown voltage and electric strength: PP insulating sheet material is destroyed under a certain strong electric field, and it loses the performance of PP insulating sheet and becomes conductive, which is called breakdown. The voltage at breakdown is called breakdown voltage (dielectric strength). Electrical strength is the quotient of the voltage when breakdown occurs under specified conditions and the distance between the two electrodes that bear the applied voltage, that is, the breakdown voltage per unit thickness. For PP insulating sheet materials, generally the higher the breakdown voltage and electrical strength, the better.
The commonly used PP insulating sheet material is generally a material with a resistivity greater than 10 to the 9th power Ω.cm. It has good dielectric properties and heat resistance, so it can prevent accidents such as creepage, leakage or breakdown. In addition, It has good thermal conductivity, moisture resistance, high mechanical strength and convenient processing.
Commonly used PP insulating sheet materials can be divided into the following categories according to different chemical properties:
(1) Inorganic PP insulating sheet materials: mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used for motor and electrical winding PP insulating sheets, switch bottom plates and PP insulating sheets.
(2) Organic PP insulating sheet materials: shellac, resin, rubber, cotton yarn, paper, hemp, silk, rayon, most of which are used to make PP insulating sheet varnish and the coated PP insulating sheet for winding wires.
(3) Mixed PP insulating sheet material: various molded PP insulating sheet materials processed from the above two materials, used as the base and shell of electrical appliances.
