︱ Insulation pad insulation pads manufacturers (days spread electric) Contact: ZHANG Gai Red phone: 13722886213 QQ: 1803804222 For more details, please visit our website: http: //www.tk104404012.icoc.cc/ Electrical Equipment Co., Ltd. Hebei days spread located in Hebei Province Gaocheng City Industrial Development Zone, Chang An Great One, is the development, production, sales and service in one of professional manufacturer of power tools and instruments. Usually voltage 10KV, the choice of not less than 6mm thick frequency voltage withstand test 10000V, 1 minute Insulation pad sheet does not breakdown; voltage 35KV, the choice of not less than 10-12mm thick frequency voltage withstand test 15000V, 1 minute without breakdown of insulation pad sheet; when the voltage of 0.4KV low pressure, the choice of not less than 3mm thick frequency voltage withstand test 3500V, 1 minute without breakdown of insulation pad sheet 1. Insulation pads technical parameters are listed crack Sheet: according to the voltage level can be divided into: 5kv, 10kv, 20kv, 25kv, 35kv be divided by color: black pads, red pads, pads can be divided according to the thickness: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm. 2. 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 meter, the 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 the width not exceeding 10mm, a length of no more than 1/10 of the total length of the plastic sheet, and not allowed to have cracks. 3. 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. 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. Insulation pads Scope and storage: Widely used in substations, power plants, power distribution room, test roommate and wild 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 to the open air to prevent avoid direct sunlight
