How to measure the mechanical strength and insulation properties of insulating materials?

Any mechanical equipment in the choice of insulating materials, the concern is nothing more than the material of the fiber material, density, permeability, uniformity and a series of mechanical strength. What is the mechanical strength of the insulating material? What are the requirements?
The mechanical strength of the EPGC202 mainly refers to the tensile strength, the stamping strength, the tear strength and the toughness, among which the insulating material is required to withstand the tensile load without being pulled The maximum stress of the break.
And the stamping strength of the insulating material refers to a measure of the ability to withstand the pressure without being broken; the tear strength is the force required to tear the insulating material to the appropriate standard; and the toughness, in the case where the polyimide glass fiber is folded or bent When the strength to meet the corresponding requirements.
 In addition, it is necessary to judge the solid insulation properties of the insulating material. The usual way is to measure the degree of polymerization of the material or to measure the content of furfural in the oil by means of high performance liquid chromatography (HPLC), so that when the equipment fails , Whether it will adversely affect the paper banding tape.
In the maintenance of insulating materials in the process, should pay attention to control the rated load of equipment, requiring the operation of the environment air circulation, heat dissipation conditions, to prevent the temperature rise and the cabinet lack of oil. Of course, to prevent oil pollution, deterioration caused by accelerated aging of insulating materials, thereby reducing its insulation performance.
