What are the classifications of electrician's safety helmets? The following are the small knowledge compiled by China's labor safety nets for you:

The classification of electrician's safety helmets can be divided into two categories: T (special use) and Y (general use) depending on the scope of application. In addition to the basic performance requirements that Category Y helmets should meet, Class T helmets should also have the special performance requirements specified in the product standards. Near-electricity alarm electrician safety helmet is to install a "close-in power pre-warmer" inside the ordinary T4 safety helmet. The power industry requires that helmets have insulation properties to prevent electric shocks, and electric (electrician) helmets are T4 helmets.

The category Y helmet means that such products should meet the basic technical requirements specified in the national standards.
