(2) According to the color can be divided into: black pad, red pad, green pad (3) can be divided by thickness:, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm.
2. Range of use and storage of insulation pads: Widely used in substations, power plants, power distribution rooms, laboratory roommates, and field live work. Should be stored in a dry and ventilated environment, away from heat sources, more than 20cm away from the ground and walls. Avoid contamination with acids, alkalis, and oils. Do not expose it outdoors to direct sunlight.
3,15KV insulation pads 1.15KV insulation pads Overview:
(1) Introduction: Strengthen the insulation of workers to the ground, rubber pads made of special rubber. Insulation mat is also called insulation pad, insulation rubber pad, insulation blanket, insulation rubber pad and so on. With a larger volume resistivity and resistance to electrical breakdown of the pad. Made of non-polar rubbers with excellent insulation properties such as NR, SBR and IIR. Anti-Static High-Voltage Insulation Pad Working Principles Used for worktops such as power distribution or countertop insulation materials.
(2) Appearance: Scratches or bumps: Depth or height must not exceed the thickness tolerance of the pad; Bubbles: Within one square meter, no more than five bubbles with an area of ​​less than 1cm2, no less than 40mm between any two bubbles; Impurities: Depth And the length should not exceed the thickness of the pad is not less than 40mm; edge uneven or spongy: the width does not exceed 10mm, the length does not exceed 1/10 of the total length of the pad; crack: not allowed 4. National Standard for Insulating Mats: No. Item Cycle Requirements Description 1 Power frequency voltage test 1 year voltage level Power frequency voltage kV Duration min Used in live equipment area High voltage 151 Low voltage 3.51 When testing, first spread insulation mats up and down with wet cloth. Or metal foil, and should be 200mm smaller than the insulating pad around the test, continuously and uniformly boosted to the voltage value specified in Table 8, keep 1min, observe the phenomenon of breakdown, if no breakdown, the test passed. When the sample is tested in stages, the edges of the two tests should be coincident.
5. General use configuration of high-voltage insulation rubber sheet:
(1) 5KV insulation pad thickness: 3mm Specific gravity: 5.8KG/m2 Color: Red, green, black (2) 10KV insulation pad thickness: 5mm Specific gravity: 9.2KG/m2 Color: red, green, black (3) 15KV Insulation Mat Thickness: 5mm Specific Gravity: 9.2KG/m2 Color: Red, Green, Black (4) 20KV Insulation Pad Thickness: 6mm Specific Gravity: 11KG/m2 Color: Red, Green, Black (5) 25KV Insulation Pad Thickness: 8mm Specific Gravity: 14.8KG/m2 Color: Red, Green, Black (6) 30KV-35KV Insulation Pad Thickness: 10mm12mm Specific Gravity: 18.4KG/m222KG/m2 Color: Red, Green, Black 6. High-voltage insulation plastic sheet features: good physical and mechanical properties, excellent insulation properties, can work in the dry -35 ~ +100 °C air requirements for high dielectric constant environment. Through the 43KV test, the working principle of the anti-static high-voltage insulation pad works normally at 660V. Widely used in substations, power plants, power distribution room, laboratory roommates and field live work. Should be stored in a dry and ventilated environment, away from heat sources, more than 20cm away from the ground and walls. Avoid contamination with acids, alkalis, and oils. Do not expose it outdoors to direct sunlight. Insulation rubber mat structure:
7, insulation pad components: insulation pads should be made of plastic insulating materials.
8, high pressure insulation plastic sheet technology and molding: the upper and lower surface of the insulation pad should not have harmful irregularities. Harmful irregularity refers to one of the following characteristics, namely defects that destroy uniformity and damage the smooth surface of the surface, such as holes, cracks, local bulges, incisions, conductive foreign matter inclusions, creases, voids, bumps, and casting marks. . Harmless irregularity refers to surface irregularities formed in the production process. Insulation pad thickness: More than five different points should be randomly selected across the insulation pad 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 shall be within 0.02mm, the diameter of the drill shall be 6mm, the diameter of the flat presser foot shall be (3.17±0.25)mm, and the presser foot shall be capable of applying a pressure of (0.83±0.03)N. The insulating mat shall be placed flat to Respecting customers who are smooth between micrometer measurements:

Tea light candle,is the kind of colored candles, also known as candle for
coffee & tea.Its small size, long burning time, is the essentials of
western family.Apply to hotels, churches, religious activity places. it is with aluminum cans casting wax, commonly
used for
birthday, burning time from 1-3 hours according to calculate
weight, generally used in bars, KTV, cafe ,and the candle light like tea light,the candle light same as the tea light,so called the tea light
candle
Widely used in substations, power plants, power distribution room, laboratory roommates and wild live work, etc., mainly made of plastic insulating materials, high-voltage insulating plastic on the surface should not have harmful irregularities. Harmful irregularity refers to one of the following characteristics, namely defects that destroy uniformity and damage the smooth surface of the surface, such as holes, cracks, local bulges, incisions, conductive foreign matter inclusions, creases, voids, bumps, and casting marks. . Harmless irregularity refers to surface irregularities formed in the production process. Specific content is as follows: Anti-static high-voltage insulation pad working principle 1, insulation pad specifications (1) according to the voltage level can be divided into 5kv, 10kv, 20kv, 25kv, 35kv
