Insulation pads 1. 1cm2 bubbles per square meter is not more than 5, the distance between any two bubbles is not less than 40mm, no cracks, tensile elongation ≥250%, permanent deformation hot air aging at 70 ℃ lasting 72 hours water absorption ≤1.5%, power frequency withstand voltage rms> 15KV, three seconds without breakdown look smooth, rugged, good elasticity 1. [Insulation pads] technical parameters are listed crack table: KV KG 5KV insulation pad thickness 3mm 5.5KG / m2 10KV insulation pads 5mm 9G / m2 15KV insulation pad 5mm 9G / m2 20KV insulation pads 6mm 11G / m2 25KV insulation rubber mat 8mm 14.5G / m2 30-35KV insulation pads 10mm 18G / m2 12mm 21.6G / m2 2.35KV insulation pads appearance and Size: scars or uneven portion of the depth or height must not exceed the plastic sheet thickness tolerance, bubbles per square Nemi, area is not in 1cm2 of air bubbles not more than 5, 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, the pad edge uneven or spongy part of a width not exceeding 10mm no longer than 1/10 of the total length of the plastic sheet, and not allowed to have cracks. 3.35KV insulation pad technology and molding: Insulating pad under the surface there should be no harmful irregularities. Harmful irregularities refers to one of the following characteristics, namely, to destroy the uniformity of the smooth contour of the damaged surface defects, such as holes, cracks, local uplift, incision, mixed with conductive particles, creases, the gap, the bump, ripple and casting marks . Harmless irregular refers to the production process of the formation of surface irregularities. 4.35KV insulation pad thickness: Throughout the insulation mat should be randomly selected more than five different points for thickness measurement and inspection. It can be used thousands of darling or the same precision instrument to measure. Micrometer accuracy should be less than 0.02mm, measured drill diameter 6mm, diameter plane presser foot (3.17 ± 0.25) mm, presser foot should be able to exert pressure (0.83 ± 0.03) N The insulating pad should be flat to place order micrometer measurements between so smooth. 5.35KV insulation pad storage: Insulating pad should be stored in a special tank, avoid direct sunlight, rain and snow Baptist leaching, extrusion and sharp objects to prevent collisions. Prohibition insulating pad oil, acids, alkalis or other harmful substances into contact with, and away from the heat source more than 1m. Storage temperature should be between 10 ℃ ~ 21 ℃.
