Hoʻohālikelike ʻia me nā lako uila maʻamau a me nā lako uila, Pono e loaʻa nā māka pono e hōʻike ai he ʻano pahū lākou. ʻO kēia ka mea i kapa ʻia ʻo ka hōʻailona pahū.
Ke kumu:
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 kinoea puhi 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 “pahū-pale,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (a i ʻole mahana wela), and/or equipment protection level symbol (a i ʻole mahana wela).
The representations of the ʻano pahū (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, Ua ʻōlelo ʻo Ga; Ua haʻi aku ʻo Ma, Mb, ʻO Gb) are well-established. No laila, we use these representations to exemplify the composition of explosion-proof markings for different types of lako uila pahū.
