Shenhai Explosion-Proof
Explosion-proof lights, distinct from other explosion-proof electrical equipment, can be categorized into five types of explosion-proof methods: flameproof, increased safety, positive pressure, non-sparking, and dust. However, these five methods are not exhaustive.
| Explosion Proof Type | Gas Explosion-proof Symbol | Dust Explosion-proof Symbol |
|---|---|---|
| Intrinsically Safe Type | ia,ib,ic | ia,ib,ic,iD |
| Exm | ma,mb,mc | ma,mb,mc,mD |
| Barotropic Type | px,py,pz,pxb,pyb,pZc | p;pb,pc,pD |
| Increased Safety Type | e,eb | / |
| Flameproof Type | d,db | / |
| Oil Immersed Type | o | / |
| Sand Filled Mold | q,qb | / |
| N-type | nA,nC,nL,nR,nAc,nCc,nLc.,nRc | / |
| Special Type | S | / |
| Shell Protection Type | / | ta,tb,tc,tD |
Due to the wide range of applications for explosion-proof lights, there are numerous varieties, including a special type that combines multiple explosion-proof methods.
