Popularization of knowledge about insulating gloves

Insulating gloves are mainly used in live working environments. Due to the continuous development of the power industry, users have stricter safety requirements for insulating gloves. In response to many questions you have about insulating gloves, C&G editor has summarized some, hoping to give you some help.

1. What is the difference between insulating gloves and ordinary protective gloves?

The biggest difference between insulating gloves and ordinary protective gloves is the material. As the name implies, insulating gloves have the function of insulating, while ordinary protective gloves do not have this function.

2. How to judge the quality of insulating gloves?

The main function of insulating gloves is to prevent electric shock to the user's hands. Therefore, the main factor for judging the quality of insulating gloves is the size of the leakage current that the gloves pass through under a certain voltage. If the leakage current is within the safe current value range, it is safe, otherwise unsafe.

3. Why keep the gloves dry when using insulating gloves?

If there is water in the insulating gloves, the insulation performance will be reduced, so when using it, it is necessary to ensure the dryness of the insulating gloves to protect the safety of users as much as possible.

4. Why should a preventive test be carried out before using insulating gloves?

In order to ensure the safety of the user's hands, a preventive test must be carried out, because the insulating gloves have a relatively long validity period. In a long period of time, due to changes caused by aging or storage conditions, they can only be used after passing the fish proof test. .

5. What is the difference between insulating gloves for live work and rubber high and low voltage insulating gloves?

Insulating gloves for live work allow live work in different types of voltage ranges. High and low voltage insulating gloves are auxiliary safety appliances that do not allow live work.

6. Why do some insulating gloves find cracks in the test?

During the high-voltage test of insulating gloves for live work, due to the non-standard water injection height or the non-dry part of the cuff of the glove, there is an arc between the two stages under high voltage, and it discharges in the air, producing a sound of beeping. Generate ionization and ionize the oxygen in the air into ozone. When the concentration of ozone increases, it will cause great oxidative damage to the rubber, causing cracks and damage to the rubber. The high pressure test is a destructive test for rubber, and it must be destroyed once. Therefore, it is stipulated that preventive tests should be carried out during use to ensure the safety of users.

In short, a series of insulating products such as insulating gloves are very necessary in live work. If you are interested in insulating gloves or other insulating products, you can contact Shanghai C&G Safety Co., Ltd..
