Itumọ:

Compared to general industrial and domestic electrical equipment, explosion-proof electrical devices must have necessary markings to indicate that they are of an explosion-proof type. This is what is referred to as the explosion-proof marking.

Idi:

Each explosion-proof electrical device should have its explosion-proof marking clearly displayed on its visible parts and nameplate. This system provides essential information, indicating that the marked electrical equipment is explosion-proof and specifying the types of gaasi ijona environments and hazardous areas where it can be safely used. Clearly, this is crucial information.

Composition:

The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: Ex (Explosion-protect) represents “bugbamu-ẹri,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (tabi otutu), and/or equipment protection level symbol (tabi otutu).

The representations of the bugbamu-ẹri iru (d, e, i, p, o, q, m, n, s), equipment classification (I, II) (IIA, IIB, IIC), temperature grading (T1, T2, T3, T4, T5, T6), and equipment protection levels (Ca, Cb, Ga; Ma, Mb, Gb) are well-established. Nitorina, we use these representations to exemplify the composition of explosion-proof markings for different types of bugbamu-ẹri ẹrọ itanna.
