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 per square meter, the area is not in 1cm2 of air bubbles not more than 5, the distance between any two bubbles is not less than 40mm, which impurity depth and length does not exceed the plastic sheet thickness not less than 40mm, sheet 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. 3. Insulation sheet and molding process: the lower surface of the insulation board 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. 4. Insulation sheet thickness: Throughout the insulation board should be randomly selected more than five different points for thickness measurement and inspection. You can use thousands of darling or the same precision measuring instruments. 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. 5. Scope and insulation board storage: Widely used in substations, power plants, power distribution room, test roommate and wild live operations. Insulation boards should be stored in a special box, avoid direct sunlight, rain and snow Baptist leaching, extrusion and sharp objects to prevent collisions.
