Insulation board, also known as insulation pads, insulation pads, insulation plates, insulation blankets, have good physical and mechanical properties, excellent insulation properties, and can be used in dry-35~+100°C environments with high requirements for intermediate dielectric constants. jobs.
Insulation panels are widely used in substations, power plants, power distribution rooms, laboratories, and field live work.
Insulation plates are made of plastic insulating materials, and there should be no harmful irregularities on the upper and lower surfaces of the insulation. The harmful irregularities of the insulating plate are one of the following features, namely the defects that destroy the uniformity and damage the smooth surface of the surface, such as holes, cracks, local bulges, incisions, conductive foreign matter inclusions, creases, voids, concave and convex ripples, and casting Signs, etc. Harmless irregularity refers to surface irregularities formed during the production process.
Insulators demand high thickness. Five or more different points should be randomly selected throughout the insulation board for thickness measurement and inspection. Measurements can be made using a thousand-centre liver or an instrument with the same accuracy. The accuracy of the micrometer should be within 0.02mm, the diameter of the drill is 6mm, the diameter of the flat presser foot is (3.17±0.25)mm, and the presser foot should be capable of applying (0.83±0.03)N pressure. The insulating plate should be laid flat to Make the micrometer measurement smooth.
