Requirements for insulating rubber pads in Guangzhou power distribution rooms

Safety is of great importance to us. From a small perspective, safety is directly related to the vital interests and lives of every production employee. From a large perspective, safety is related to the image, efficiency, survival and development of the entire enterprise. From various media reports, and even from what I have seen and heard about, various safety accidents have brought serious losses and pain to individuals, families and society. Jinneng Electric sincerely looks forward to cooperating with you! Jinneng Electric solemnly promises: All products purchased from our company will be returned or exchanged unconditionally within days if they fail to pass the test!
What are the specifications of insulating rubber pads

) Can be divided according to voltage level
) Can be divided according to color: black rubber pad, red rubber pad, green rubber pad
/> ) can be divided according to thickness, 3
Insulation pad
Features:
Good physical and mechanical properties, excellent insulation properties, can be used in dry ~+℃ air with high dielectric coefficient requirements work in an environment. Passed 3 tests and works normally.
Insulating rubber pads
According to function, they are divided into:
) Anti-slip insulating rubber pads Black anti-skid insulating rubber pads, Green anti-skid insulating rubber pads, Red anti-skid insulating rubber pads
) Lettering insulating rubber pads *Insulating rubber pad, *Insulating rubber pad, *Insulating rubber pad
) Flame-retardant insulating rubber pad - if dropped on the ground, the fire will go out in seconds
) Acid and alkali resistant insulating rubber pad
) With zebra crossing Warning function of insulating rubber pads
Detection of insulating rubber pads
Pros and cons:
. The lighter the specific gravity of the rubber pad, the better the quality, high glue content, less impurities, strong toughness, and good tensile properties
.Pull the cross section or surface of the rubber pad with your hands. High-quality rubber pads will not slag or foam, because inferior rubber pads mixed with a large amount of talcum powder will drop slag
. Bend one corner of the rubber pad with force. , good rubber pads do not leave white creases
Quality characteristics of insulating rubber pads
:
There are no more than one bubble per square meter, the distance between any two bubbles is not less than 1, and there are no cracks.
Tear off elongation and never deform.
Hot air aging lasts for hours at ℃.
Water absorbency.
The effective value of power frequency withstand voltage can be maintained for 3 seconds without breakdown.
Smooth appearance, no unevenness, good elasticity.
Precautions for use and storage of insulating rubber pads
During use, the ground should be flat and free of sharp and hard objects. When laying insulating rubber pads, the joints of the insulating rubber pads should be flat and not curled to prevent operators from falling when inspecting equipment or switching operations.
During use, if the insulating rubber pad is found to have cracks, scratches, thickness reduction, etc. that are insufficient to ensure the insulation performance, it should be replaced in time.
The insulating rubber pad should be protected from direct sunlight or sharp metal scratches. When stored, it should be kept away from heat sources (heaters, etc.) to prevent aggravation of aging and deterioration, resulting in a decrease in insulation performance.
The insulating rubber pad should be kept dry and clean, and be careful to prevent contact with acids, alkalis and various organic substances to avoid aging, cracking or becoming sticky after corrosion, thereby reducing the insulation performance.
The insulating rubber pad should be cleaned with soapy water every six months.
