Insulation rubber sheet, insulation rubber board, insulation rubber matapplication scope and storageinsulation blanket, insulation rubber mat, and many other names, but it is collectively referred to as insulation rubber mat.

Insulation rubber sheets, insulation rubber boards, and insulation rubber mats are widely used in substations, power plants, distribution rooms, test rooms, and live outdoor operations. They are mainly made of rubber insulation materials. The upper and lower surfaces of the insulation mat should not have harmful irregularities, which refer to one of the following characteristics: defects that destroy uniformity and damage the smooth surface profile, such as small holes, cracks, local bulges, cuts, embedded conductive foreign objects, folds, voids,凹凸波紋, and casting marks. Harmless irregularities refer to surface irregularities formed during the production process. Specific details are as follows:

2.Methods:

Widely used in substations, power plants, distribution rooms, test rooms, and live outdoor operations.

Should be stored in a dry and ventilated environment, away from heat sources, and at least 20cm above the ground and walls. Avoid contamination by acids, alkalis, and oils. Do not store outdoors to prevent direct sunlight. 

15KV insulation rubber sheet, insulation rubber board, insulation rubber matOverview:

①. Introduction: Enhances the insulation of workers from the ground, made from special rubber. Insulation rubber sheet is also known as insulation rubber board, insulation rubber mat, insulation blanket, insulation rubber mat, etc. It is a rubber mat with high volume resistivity and resistance to electrical breakdown. Made from non-polar rubbers with excellent insulation properties such as NR, SBR, and IIR. Used as desktop or floor insulation material in work environments like power distribution.

②. Appearance: Spots or unevenness: depth or height must not exceed the thickness tolerance of the rubber mat; Bubbles: no more than 5 bubbles per square meter with an area less than 1cm2, and the distance between any two bubbles should be at least 40mm; Impurities: depth and length should not exceed the thickness of the mat, and not less than 40mm; Uneven edges or sponge-like texture: width should not exceed 10mm, length should not exceed 1/10 of the total length of the mat; Cracks: not allowed （2）．National standards for insulation rubber sheets, insulation rubber boards, and insulation rubber mats: Serial number Item Cycle Requirement Description 1 Power frequency withstand voltage test 1 year Voltage level Power frequency withstand voltage kV Duration min Used in live equipment areas High voltage 15 1 Low voltage 3.5 1 During the test, wet cloth or metal foil should be placed above and below the insulation rubber sheet, insulation rubber board, or insulation rubber mat, and should be 200mm smaller than the perimeter of the tested mat. The voltage should be increased continuously and uniformly to the value specified in Table 8, maintained for 1min, and observed for any breakdown. If there is no breakdown, the test is passed. When testing in segments, the edges of the two segments should overlap.

（3）．15KV insulation rubber sheet, insulation rubber board, insulation rubber mat characteristics: Good physical and mechanical properties, excellent insulation performance, can operate in dry air environments from -35~+100℃ with high dielectric requirements. Tested at 43KV, normally operates at 660V. Widely used in substations, power plants, distribution rooms, test rooms, and live outdoor operations. Should be stored in a dry and ventilated environment, away from heat sources, and at least 20cm above the ground and walls. Avoid contamination by acids, alkalis, and oils. Do not store outdoors to prevent direct sunlight.
