Dielectric gloves are a protective agent for hand to electricity. Their main purpose is the reliable protection of human hands from touching the instruments and parts that are under electrical stress.
Dielectric gloves provide protection against shock
Insulating mittens are considered a real protective agent in an electrical installation up to 1000 volts. Having studied this article, you will learn the appointment, rules of use and methods of testing dielectric gloves.
Glove varieties
Most often manufacturers make these sheets of rubber or latex gloves. All gloves have a universal size. If there is a negative temperature on the street then knitted crags should be put on the gloves. This allows you to protect your hands from supercooling and charming.
Mittens for an electrician are made of dielectric materials
All protective agents can be divided into the following types:
- Bobbin and five plated.
- Seamless and gloves with seams.

In electrical installations, the use of insulating mittens, which have a "eV" or "en" mark. The designation "EV" on gloves indicates that the material is able to protect a person from electricity with a voltage over 1000 volts. The "En" designation is considered the main protective coating from the electric current to 1000 volts. These designations are indicated in GOST 12.4.103-83.
Check strength
The test of electrical insulating gloves is simple necessity. Check should follow once every six months. The frequency of verification will depend on the mark "EV" and "En". You can check the gloves as follows: water is poured into the container and water is also poured into the sample of dielectric gloves. The water temperature may vary from 10 to 40 degrees. The distance from the edge of the glove to the water should not exceed 55 mm. Krag edges should remain dry. In the photo below you can consider this process in more detail.

Verification of dielectric gloves with water tank
The voltage that enters the body of the container and the electrode, which goes inside the glove has its own requirements and equals 6 kW. The duration of the test is 1 minute. The milliammeter should show the current value that passes through the crags of 6 mA. After testing, the dielectric material from which the mittens are made should dry. For this gloves are placed in a special reservoir.
Shp-200.
After the drying is completed, the insulating gloves put the test stamp on which the dates of the use of protective crag are prescribed. You can see the example of the stamp in the photo below.
After testing you need to put a stamp
Apply a stamp follows a special inclusive paint. Then all information is entered into a log in which the test of protective agents is indicated. If there is a need then, after completing all the above procedures, a protocol is issued. The form of the protocol is as follows:
If necessary, data on the results of checking gloves are entered into the protocol
There are other ways to check dielectric gloves for electricians. You can get acquainted with one of them after studying the video below.
Rules for using gloves
Any dielectric material from which gloves produce has its own service life. Therefore, before proceeding with their use, you first need to check the shelf life. During the inspection, your attention should be paid to the following indicators:
- the presence of an inspection stamp;
- the presence or absence of various kinds of damage;
- lack of pollution;
- Cracks or other damage.
To check the product for cracks or punctures you need to twist mittens from edges to fingers. Thanks to this, you will see the dielectric material of krag has damage. You can get acquainted with the method of such a check in more detail after viewing the picture placed below.
Checking dielectric gloves for punctures
Many electricians regularly think about how can the dielectric material be protected from which protective gloves are made? To ensure protection, you will need to wear on top of a leather mittens or tarpaulin.
It's important to know! In the process of work it is forbidden to complete the edges of gloves. After each work, the product must be washed with soda or soap-based solution. Then the product must be carefully dried.
Instructions for the use of krag, which includes the dielectric material is standard. Each production instructed on the use of dielectric gloves. The main purpose of the electrically insulating mittens is to protect against electric shock. You do not need to neglect the rules, as you can get a blow to an electric shock.
