Scope

This part of GB 3836 specifies the requirements for the construction, testing and marking of electrical equipment protected by type "n" in explosive gas atmospheres of Class II. This section applies to electrical equipment with a rated voltage not exceeding 15 kV DC or AC rms. This part of GB 3836 applies to non-sparking electrical equipment, and also applies to those parts or circuits that generate arcs, sparks or have hot surfaces, and use one of the methods specified in this part to protect electrical equipment that cannot cause ignition of the surrounding explosive gas atmosphere. equipment. Several different methods specified in this section can be used together with other methods specified in GB 3836.1-2010 to achieve protection purposes. This part is a supplement and modification to the general requirements of GB 3836.1-2010, as shown in Table 1. When there is a conflict between the requirements of this section and the requirements of GB 3836.1-2010, the requirements of this section shall take precedence.
