Insulation sheet technical parameters: According to the voltage level can be divided into: 5kv, 10kv, 20kv, 25kv, 35kv, 500kv and so on. Be divided by color: black insulation sheet, insulation sheet red, green insulation sheet. Can be divided according to the thickness: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm 2. Exterior insulation sheet and Size: scar or uneven portion of the depth or height shall not exceed the plastic sheet thickness tolerance, bubbles under the surface of the insulation plate per square meter should be no harmful irregularities. Harmful irregularities is one of the following characteristics, namely the destruction uniformity, damage the surface smooth contour defects such as holes, cracks, local uplift, incision, mixed with conductive particles, creases, the gap, bump, ripple and casting marks . Harmless irregular refers to the production process of the formation of the surface irregularities. 3. Insulation sheet thickness: Throughout the insulation board should be randomly selected more than five different points for thickness measurement and inspection. You can use a micrometer or similar instrument to measure accuracy. Micrometer accuracy should be within 0.02mm, measured drill diameter of 6mm, the diameter of the plane of the presser foot is (3.17 ± 0.25) mm, presser foot should be able to exert pressure (0.83 ± 0.03) N The insulation board should be flat to place order micrometer measurements between so smooth. 4. Insulation sheet Storage: insulation boards should be stored in a special box, avoid direct sunlight, rain and snow Baptist leaching, extrusion and sharp objects to prevent collisions. Prohibit insulation board with oil, acids, alkalis or other harmful substances into contact, and more from the heat source 1m. Storage temperature should be between 10 ℃ ~ 21 ℃. 5. Scope and insulation board storage: Widely used in substations, power plants, power distribution room, laboratory and field live operations. Should be stored in dry and ventilated environment, away from heat, more than 20cm off the ground and walls. Avoid being affected by acid-base and oil pollution, not open to prevent direct sunlight, the area is not in 1cm2 of air bubbles not more than 5, the distance between any two bubbles is not less than 40mm, the depth and length of which does not exceed the impurity sheet thickness not less than 40mm , rubber edge uneven or spongy part of the width not exceeding 10mm, length does not exceed 1/10 of the total length of the plastic sheet, and does not allow cracks.
