Insulation board, also known as insulation pads, insulation pads, insulation pads, insulation blanket. Widely used in insulation pad substations, power plants, power distribution room, laboratory and field live operations. Plastic type insulation materials, insulation pad under the surface there should be no harmful irregularities. Insulation pads harmful irregularities is one of the following characteristics, namely the destruction uniformity, smooth surface contour defect damage, such as holes, cracks, local uplift, cuts, mixed with conductive particles, creases, gaps, uneven ripples and casting signs. Harmless irregular production process is the formation of surface irregularities. Details are as follows: 1, insulation board specifications: (1) in accordance with the voltage level can be divided into 5kv, 10kv, 20kv, 25kv, 35kv (2) can be divided by color: black pads, red pads, pads (3 ) can be divided by the thickness: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm.. 2, insulation boards using conventional configuration: (1) 5KV insulation pad thickness: 3mm proportion: 5.8KG/m2 colors: red, green, black; (2) 10KV insulation pad thickness: 5mm proportion: 9.2KG/m2 Color: red, green, black; (3) 15KV insulation pad thickness: 5mm proportion: 9.2KG/m2 colors: red, green, black; (4) 20KV insulation pad thickness: 6mm proportion: 11KG/m2 colors: red, green black; (5) 25KV insulation pad thickness: 8mm proportion: 14.8KG/m2 colors: red, green, black; (6) 30KV-35KV insulation pad thickness: 10mm 12mm gravity: 18.4KG/m2 22 KG/m2 color: red, green, black. 3, insulation board features: good mechanical properties, excellent insulation properties, can work in dry air -35 ~ +100 ℃ high dielectric coefficient environments. 4, insulation boards and molding process: the lower surface of the insulation board should be no harmful irregularities. Harmful irregularities refers to one of the following characteristics, namely the destruction uniformity, damage the surface smooth contour defects such as holes, cracks, local uplift, cut, mixed with conductive particles, creases, gaps, uneven ripples and casting marks . Harmless irregular production process is the formation of surface irregularities. 5, the insulation thickness: Throughout the insulation board should randomly select five or more 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, measuring 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 of insulation pad should lay flat to between the micrometer measurements are so smooth. 6, insulation boards with national standards: 10KV voltage power distribution room, choose 8mm thick frequency voltage withstand test 10000V 1 minute without breakdown, the power frequency withstand voltage test 18000V, 20 seconds breakdown voltage distribution room 35KV 10-12mm thick work. frequency pressure experiments 15000V 1 minute without breakdown, the power frequency withstand voltage test 26000V, 20 seconds breakdown election 5mm thick low-pressure distribution room below 500V power frequency withstand voltage test 3500V 1 minute without breakdown, the power frequency withstand voltage experiments 10000V, 20 seconds without breakdown!
