Appearance and Specifications of Safety Insulating Rubber MatsIntroduction:

Insulating rubber mats, also known as insulating pads, insulating sheets, or insulating blankets, are widely used in substations, power plants, distribution rooms, laboratories, and live working outdoors.

Made from rubber insulating materials, the upper and lower surfaces of the insulating mat should be free from harmful irregularities. Harmful irregularities refer to defects that破壞均勻性、損壞表面光滑輪廓, 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.

Features of Insulating Rubber Mats

Excellent physical and mechanical properties, superior insulation performance, suitable for use in dry environments with high dielectric requirements within a temperature range of -35~+100°C.

Manufacturing Process and Forming of Insulating Rubber Mats:

The upper and lower surfaces of the insulating mat should be free from harmful irregularities. Harmful irregularities refer to defects that破壞均勻性、損壞表面光滑輪廓, 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.

Thickness of Insulating Rubber Mats:

Randomly select more than 5 different points across the entire insulating mat for thickness measurement and inspection. Use a micrometer or an instrument of equivalent accuracy for measurement. The micrometer should have an accuracy within 0.02mm, with a measuring anvil diameter of 6mm and a flat pressure foot diameter of (3.17±0.25)mm. The pressure foot should apply a force of (0.83±0.03)N. The insulating mat should be laid flat to ensure smooth measurement with the micrometer.

National Standards for Insulating Rubber Mats:

For 10KV配電室 voltage: 8mm thickness, withstand power frequency voltage test of 10000V for 1 minute without breakdown; breaks down at 18000V in 20 seconds. For 35KV配電室 voltage: 10-12mm thickness, withstand power frequency voltage test of 15000V for 1 minute without breakdown; breaks down at 26000V in 20 seconds. For low-voltage配電室: 5mm thickness, below 500V, withstand power frequency voltage test of 3500V for 1 minute without breakdown; withstands 10000V for 20 seconds without breakdown!
