Shanxi Houma 12mm black insulating pad factory direct supply price

 High voltage insulation pad and an insulating blanket, insulating pad, insulating rubber plate, insulating rubber, insulating rubber mats. Good quality insulation pads no smell, no bubbles, no pits, smooth surface neat and clean, good insulation properties, materials and environmental protection, has high elasticity, work in the dielectric environment, the maximum insulation voltage of 100,000 volts. Widely used in the use of high voltage insulation pad substations, power plants, power distribution room, test roommate and wild live operations, mainly plastic type insulation materials, insulation mat under the surface 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. High voltage insulation pad specifically outlined as follows: 1, insulation pads Specifications (1) In accordance with the voltage level can be divided into 5kv, 10kv, 20kv, 25kv, 35kv (2) can be divided by color: black insulation pads, red insulation pads , green insulation pads (3) can be divided according to the thickness: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm 2, Scope and storage: Widely used in substations, power plants, power distribution room, test Use 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. 3, insulation pads Overview: (1) Introduction: strengthening the staff of the insulation, made of special rubber rubber mat. Insulation pads, also known as insulating plastic sheet, insulating rubber mats, insulation blanket, insulating rubber mats. It has a larger volume resistivity and electrical resistance breakdown pads. Excellent non-polar rubber with NR, SBR and IIR insulation properties. For table or floor insulation material distribution and other occasions. (2) the appearance of: scarring or uneven: the depth or height must not exceed the pad thickness tolerance; Bubble: 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; impurity: Depth and length of not more than pad thickness not less than 40mm; edge uneven or spongy: width not exceeding 10mm, length does not exceed 1/10 of the total length of the pad; crack: not allowed 2. National standards of insulation pads: No. Item Description 1 cycle requirements frequency voltage withstand test on the first insulation pads bunk 1 year power frequency withstand voltage kV duration min charging device for use in high pressure 151 low pressure area 3.5 1 test On a damp cloth or metal foil, and it should be higher than the measured around the insulation pads 200mm, continuous and uniform boost to the voltage value specified in Table 8 for 1min, to observe whether the breakdown phenomenon, without breakdown, the test passed. Sample segmentation test, two test edge to overlap. High voltage insulation pad structure 1, insulating pad composition: Insulation rubber pad with plastic type insulation materials. 2, 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. 3, insulating rubber mat 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. 4, the national standard: power distribution room voltage 10KV election 8mm thick frequency voltage withstand test 10000V 1 minute breakdown in the frequency pressure experiments 18000V, 20 seconds breakdown in the distribution room voltage 35KV 10-12mm thick frequency tolerance. pressure experiments 15000V 1 minute breakdown in the frequency pressure experiments 26000V, 20 seconds breakdown in the distribution room Low election 5mm thick frequency voltage withstand test below 500V 3500V 1 minute breakdown in the frequency pressure experiments 10000V 20 seconds without breakdown. I produced the insulation sheet indicators have reached the national standard, provide security for your work, please call.
