The Main Characteristics of Insulating Materials
In electrical technology, the insulating material usually refers to the 9 square Ω.Cm material with a resistance coefficient greater than 10. The role of insulating material is to separate electrical parts of different electric potential in electrical equipment.
Therefore the insulation material has good dielectric properties, is to have the insulation resistance and compressive strength is very high, to avoid leakage, creepage and breakdown; secondly, heat insulation performance is better materials, mainly to ensure that not because of the heat effect of long-term performance and change; in addition, thermal conductivity good resistance to moisture and has high mechanical strength and easy processing etc..
The insulating materials commonly used in electricians can be classified into three types: inorganic materials, organic insulating materials and mixed insulating materials according to their chemical properties.
