What are the lifetime of insulating gloves, insulating shoes and insulating blankets?
Insulating gloves to prevent electric shock injury is the main body through the current cause, so the insulation performance is good or bad depends on the size of the glove by leakage current at a certain voltage, if the leakage current is within the safe current numerical range is safe, otherwise it is not safe. If a certain voltage is applied, even though no breakdown occurs, the leakage current is too large, which can cause bodily harm.
Insulation gloves are available for a long time. Due to their aging or storage conditions over a long period of time, it is necessary for users to conduct preventive tests before use. Insulation gloves beyond the shelf life must be tested before they are ready for use.
The shelf life of insulated gloves is 18 months, but preventive tests must be carried out for 6 months. The preventive test is the strict regulation of the electric power industry, which guarantees the safety of the person.
Wearing insulation gloves in dry state is a problem that users must pay attention to, because the insulating gloves, if they contain a certain amount of water, will greatly reduce the volume resistance and surface resistance of their insulators. Water is a conductor, because of the existence of water, insulation performance of insulators is greatly reduced or even destroyed. There are a lot of impurities in the water, in certain circumstances (such as heat, light, electricity and other chemical changes) and the formation of a conductive body, destroy the insulation performance, so keep insulating gloves dry, can improve the safety performance greatly.
