Insulated shoes are a kind of safety shoes made of insulating materials. Insulation means that the human body needs to be isolated from the conductor, and the function of insulating shoes is to isolate the human body from the conductor of the earth. It is one of the necessary tools for decoration. Let's introduce the signs and precautions of insulated shoes for everyone.

according to the requirements of the new standard, the thickness of the outsole of insulating shoes should not be less than 4 mm without patterns, and it should not be less than 6 mm when patterns cannot be measured. At present, in the market, the phenomenon of replacing labor insurance insulating shoes with living soles often appears. Even the thinnest part of the sole is less than 6 mm. The uppers or soles of insulated shoes purchased by enterprises should have standard numbers, insulation words and voltage values. Enterprises should also know the qualifications of manufacturers.
The length of wear marks on the outsole of electric insulating leather shoes should be no more than 1mm; The wear reduction of electrically insulating cloth shoes is not more than 1.4cm3; The wear reduction of 15kv and below electrical insulating rubber boots is not more than 1.cm3; The wear reduction of electrical insulating rubber boots of 2kv and above is not more than 1.9cm3.
signs and precautions of insulating shoes
precautions
1. Insulating shoes are suitable to be worn as auxiliary safety appliances and labor protection articles when working on power equipment with AC power of 5Hz, below 1V or below 15V. Workers use insulated leather shoes, which can cooperate with basic appliances to touch live parts, and can be used to prevent clicks caused by step voltage. Step voltage refers to the potential difference between two points in the direction of the maximum potential gradient on the ground when electrical equipment is grounded. < P > 2. This product should be protected from moisture, and it is strictly prohibited to use it after it gets wet. Once it gets wet, it should be naturally dried in a ventilated and cool place to avoid deformation and damage of leather shoes. After the sole is pierced by a foreign object, it cannot be used as an insulating leather shoe.
3. Pay attention to leather surface maintenance of leather shoes and polish shoes frequently. The wiping method is as follows: firstly, wipe off the dust on the surface of leather shoes with a clean soft cloth, then squeeze the shoe polish on the cloth and evenly spread it on the upper, and then wipe it after a while (the shoe polish is slightly dry).
4. Insulating shoes should not be worn in rainy days, let alone washed, otherwise it is easy to break wires, degum, decolorize and pan-salt frost.
5. Insulated shoes should not come into contact with oil, acid, alkaline and sharp substances to prevent corrosion, deformation and damage.
VI. When wearing colored leather shoes (including white shoes), we should pay special attention not to touch sewage, dirt, tea stains, cola, etc. Otherwise, stains will be left, which will damage the primary colors of leather shoes.
VII. It is normal for leather shoes to be slightly wrinkled and deformed after wearing.
VIII. After the insulated shoes are wet or sweaty, it is easy to appear the phenomenon of pan-salt frost. In case of pan-salt frost, use gauze or cotton with a small amount of warm water to wipe the white salt frost on the vamp, put the shoes in a ventilated place to dry, and then wipe them with shoe polish, and they can be restored to their original state after repeated times. Therefore, keep the leather shoes dry.
9. When insulating shoes are stored, they should be kept clean and dry, polished with shoe polish, and naturally laid flat: after storage for a period of time (especially in rainy season), they should be ventilated and dried frequently, and the shoe polish should be wiped again to prevent mildew.
packaging method
the contents of a sign should include:
1. There should be a standard number, the word "electrical insulation" (or EH in English), lightning mark and voltage withstand value on the upper or sole of each pair of shoes;
2 name of the manufacturer, name of shoes, name of products or trademarks, date of production, and stamp of ex-factory inspection of electrical insulation performance.
two packages
1 each pair of boots should be packed in paper bags, plastic bags or cartons. The bag box should contain the following contents: product name (for example: 6 kV insulated leather shoes with cowhide leather, 5 kV insulated cloth rubber shoes, 2 kV insulated rubber boots, etc.), standard number, manufacturer name, shoe number, trademark and instructions for use.
2 large packages shall be packed in cardboard boxes, with firm sealing and tightly bound boxes. The box surface shall contain the following contents: standard number, manufacturer's name and address, postcode, product name, product specification, quantity, trademark, production date, box number, size and volume (or weight).
III. Transportation
1 During transportation, there must be a cover to prevent rain, and it must not be put together with acid, alkali or other corrosive substances.
the so-called insulation means that the charged body is sealed with insulating material, so as to isolate the charged body or conductors with different potentials, so that the current can flow through a certain path. Good insulation is a necessary condition to ensure the normal operation of equipment and lines. The above is the information content brought to you today. I hope you will like it.
