Physical Properties Of Insulating Sleevings
Jul 08, 2017

     Insulating paper is the function of the electrical equipment in the electric potential of the different parts of the live isolated. Therefore, the insulation paper should first have a high insulation resistance and compressive strength, and can avoid leakage, breakdown and other accidents. Second, the heat resistance is better, avoid aging and deterioration due to long-term overheating, in addition, there should be good thermal conductivity, moisture-proof resistance and high mechanical strength and easy processing. According to the above requirements, the performance indexes of insulating paper are insulation strength, tensile strength, specific gravity, expansion coefficient and so on.Insulating Sleevings
     Insulation compressive strength: the higher the voltage at both ends of the insulator, the greater the electric field force in the material, the more easily the ionization collision, resulting in the breakdown of the insulator. The lowest voltage that causes an insulator to penetrate is called the breakdown voltage of the insulator. When the 1 mm thick insulating paper breakdown, the need to add the voltage kv number is called insulating paper insulation compressive strength, referred to as insulation strength. As insulating paper has a certain degree of insulation strength, a variety of electrical equipment, a variety of safety appliances (electrical pliers, inspection pen, insulating gloves, insulation rods, etc.), a variety of electrical materials, manufacturers are required to allow the use of certain voltage, known as rated voltage. When using the voltage must not exceed its rated voltage value, in order to avoid an accident.Insulating Sleevings
    Insulating kraft paper is used as packing material. High strength. usually brownish. The kraft pulp of half drift or whole float is light brown, creamy color or white. Quantitative 80~120g/m2. Fracture length generally above 6000m. Tearing strength, rupture power and dynamic strength are very high. Much for the web, there is also flat paper. The Kraft softwood pulp was used as raw material, and was made from the long net papermaking machine by beating. Can be used as cement bag paper, envelope paper, adhesive paper, asphalt paper, cable protection paper, insulating paper and so on. Insulating Kraft paper has a very high tensile force, there are single, double light, stripes, no stripes and so on. It is mainly used in wrapping paper, envelopes, cardboard bags and printing press rollers.
