What Is Insulating Shoes?

Unified safety insulating shoes

It's a safety shoe made of insulating materials.

The application scope of electrical insulation shoes is clearly pointed out in the new standard: electrical insulation shoes and cloth electric insulation shoes under experimental voltage less than 15KV are applied in the working environment below the power frequency (50-60F) 1000V. The electrical insulating rubber shoes of the electric power cities above 15KV are applicable to the working environment of 1000V frequency above.

The so-called insulation refers to the use of insulating materials to seal the electrified body, so as to isolate the conductor of the charged body or different potential, so that the current can be circulated in a certain way.

Good insulation is a necessary condition to ensure normal operation of equipment and lines, and is also an important measure to prevent electric shock accidents.

Insulating materials often play other roles: cooling, mechanical support and fixing, energy storage, arc extinguishing, moisture-proof, mildew proof and conductor protection.

The insulation shoes we usually refer to mainly refer to electrical insulation shoes. Next, let's look at the use of electrically insulating shoes.

:

The new standard stipulates that electrical insulation shoes as a safety auxiliary appliance for electrical work, as a labor safety manager, should clearly understand this point.

Some managers who lack electrical knowledge mistakenly believe that 6KV insulation shoes or 5KV cloth insulated shoes are widely used in the 6KV or 5KV environment, which is very wrong.

In electrical safety management, insulation tools are divided into basic safety appliances and auxiliary safety appliances.

The so-called basic safety appliances refer to safety appliances that are strong enough to withstand the electrical application voltage, such as insulation rods, insulation clamps and insulation towers.

Auxiliary safety appliances are not enough to withstand the voltage of electrical operation. In electrical operations, the basic safety appliances (such as insulating pads, insulating shoes) must not be exposed to live parts.

But it can prevent the step voltage from hurting people.

Insulated shoes and cloth insulated shoes are mainly used below 1000V for auxiliary safety appliances.

What matters do electrical workers need to pay attention to when they use insulating shoes?

First, the insulation shoes should be properly selected according to the voltage level of the workplaces. Low voltage insulation shoes are prohibited to be used as safety auxiliary appliances on high-voltage electrical equipment. High voltage insulating shoes (boots) can be used as auxiliary safety appliances for high voltage and low voltage electrical equipment.

However, it is not possible to contact the electrical equipment directly with the hand or wear the low-voltage or high voltage insulating shoes (boots).

Two, cloth insulation shoes can only be used in dry environment, to avoid wet cloth.

Three, the use of insulating shoes (boots) must not be damaged.

Four, when wearing insulating boots, the trouser sleeves should be covered in the boots.

When wearing insulating shoes, the trousers should not be long and the height of the welds along the sole should not be long enough to keep the cloth dry.

Five. The rubber base of non acid and alkali oil should not contact with acid and alkali oil substances, and should prevent sharp injuries.

Low voltage insulating shoes can not be used as insulating shoes if the bottom patterns are polished and exposed to internal colors.

Six, when purchasing insulated shoes (boots), it is necessary to check whether there are permanent insulation marks on the shoes, such as red lightning signs, and how many excellent resistance to the soles, etc.; whether there are any certificates, safety certificates and production license numbers in the shoes.

Upper and logo of electrically insulating shoes:

According to the new standard, the thickness of the sole of the electrical insulating shoe should not be less than 4 mm in thickness, and the thickness should not be less than 6 mm when the pattern cannot be measured.

In the present market, the phenomenon of replacing the insulating shoes with the sole of living shoes often appears in the market.

It is the thinnest part of the sole, which is less than 6 millimeters.

The shoe or shoe sole of the insulated shoes purchased by the enterprise shall have standard number, insulation type and voltage value.

Enterprises should also know the qualification of manufacturers.

The length of the electric insulation shoe shoe outsole should not be larger than 10mm, the abrasion loss of the electric insulation shoe is less than 1.4cm3; the abrasion loss of 15kV and electric insulation rubber boots is not greater than 1.0cm3; the wear reduction of the electric insulating rubber boots of 20kV and above is not more than 1.9cm3.

Electrical insulation shoes should be adhered to in preventive tests.

Electrical insulation shoes new standard GB12011 - 2000 from production, packaging, pportation, storage, use has made specific provisions.

It not only restricted the continuous improvement of the quality of manufacturers, but also put forward new requirements for the users of products: when used, sharp shoes should be avoided to puncture the soles, while the vamp should be kept dry when used to avoid high temperature and corrosive substances.

In particular, the labor safety supervision department should conduct handover tests on new products purchased for insulation shoes.

After 6 months of wearing the product, a preventive test should be made. For sharp instruments, the defective products should not be used as insulating shoes again.

Preventive test, for 6KV skin insulation shoes, should use 5KV voltage detection.

5KV cloth shoes are tested by 3.5KV.

The implementation of new GB12011-2000 standards is a common responsibility of manufacturers and enterprises.

Only by implementing the standards and grasping the requirements of standards can we reduce the safety accidents caused by electric shock.

GB12011-2000 electrical insulation shoes new standard is conducive to manufacturers to improve product quality, is conducive to enterprise safety and production management, improve the enterprise to prevent electric shock accident safety management level and safety operation level.

How to identify the signs of insulating shoes?

The content should include:

1 standard numbers, electrical insulation words (or English EH), lightning marks and voltage withstand values should be provided on each side of the shoes or on the sole.

2 manufacturer's name, shoe name, product or trade mark, date of production and electrical insulation performance of factory inspection seal.

Packaging of insulated shoes

1 each pair of boots is packed in paper bags, plastic bags or cartons.

The following items should be included in the bag case: product name (6 kV leather shoes, 5 kV insulated cloth shoes, 20 kV insulating rubber boots, etc.), standard number, manufacturer's name, shoe number, trademark and instructions for use.

2 cardboard boxes for packaging applications should be firmly sealed and the boxes should be tightly packed. The following contents should be included in the box: standard number, manufacturer's name and address, zip code, product name, product specification, quantity, trademark, production year, box number, size and volume (or weight).

Transportation and storage of insulated shoes

1 during pportation, there must be a covering to prevent rain, and not to be mixed with acid or alkali or other corrosive substances.

2 place should be placed in dry and ventilated warehouse to prevent mildew.

Stack away from the ground and walls above 20cm, leaving all heating bodies outside 1 m.

Avoid being affected by oils, acids and bases or other corrosive products.

3 the term is generally 24 months (counting from the date of production), and the products that are over 24 months must be tested for electrical performance preventability. Only those shoes that meet the requirements of tables 4 and 5 of this standard can be sold or used by electrical insulating shoes.
