Increased safety in explosion-proof design inherently focuses on elevating safety levels. This approach ensures that the equipment does not generate electrical arcs or hazardous high temperatures during standard operation. To enhance safety, the design incorporates additional sealing measures, safeguarding against dangerous temperatures, arcs, and sparks in both the internal and external parts of the equipment.
Internally, components prone to creating arcs or sparks are excluded. For instance, an nevýbušná spojovacia skrinka houses only terminal blocks. In contrast, an nevýbušná ovládacia skrinka is devoid of active components, featuring only indicators, buttons, potentiometers, and similar passive elements. In composite explosion-proof accessories, the wiring chamber is isolated from the ohňovzdorné chamber using explosion-proof putty.
