Insulating rubber sheet, insulating rubber board, insulating rubber mat Composition:

Insulating rubber mats should be made of rubber-based insulating materials.

(2). Insulating rubber sheet, insulating rubber board, insulating rubber mat Process and Molding:

The upper and lower surfaces of the insulating mat should be free from harmful irregularities. Harmful irregularities refer to one of the following characteristics: defects that destroy uniformity or damage the smooth surface profile, such as small holes, cracks, local bulges, cuts, embedded conductive foreign objects, folds, voids, concave-convex waves, and casting marks. Harmless irregularities refer to surface irregularities formed during the production process.

(3), Insulating rubber sheet, insulating rubber board, insulating rubber mat Thickness:

Thickness measurement and inspection should be conducted at more than five different randomly selected points across the entire insulating mat. A micrometer or an instrument of the same accuracy can be used for measurement. The accuracy of the micrometer should be within 0.02 mm, the measuring tip diameter should be 6 mm, the flat presser foot diameter should be (3.17±0.25) mm, and the presser foot should be able to apply a pressure of (0.83±0.03) N. The insulating mat should be laid flat to ensure smoothness during micrometer measurement.

(4), Insulating rubber sheet, insulating rubber board, insulating rubber mat National Standard:

For a 10KV substation voltage, choose 8mm thickness, power frequency withstand voltage test 10000V for 1 minute without breakdown, and power frequency withstand voltage test 18000V for 20 seconds with breakdown. For a 35KV substation voltage, choose 10-12mm thickness, power frequency withstand voltage test 15000V for 1 minute without breakdown, and power frequency withstand voltage test 26000V for 20 seconds with breakdown. For low-voltage substations, choose 5mm thickness, below 500V, power frequency withstand voltage test 3500V for 1 minute without breakdown, and power frequency withstand voltage test 10000V for 20 seconds without breakdown.
