ගල් අඟුරු පතල් විදුලි උපකරණ සඳහා පිපිරුම්-සනාථ කිරීමේ හැකියාව නැතිවීම යන්නෙන් අදහස් කරන්නේ කුමක්ද?

1. Explosion-proof joint surfaces fail due to issues with bolt fixation, including scenarios where bolts are missing or insufficiently tightened.

2. Non-compliance of explosion-proof surface parameters, like improper gaps or inadequate surface roughness in joint surfaces.

3. Inadequacy in explosion-proof enclosure entry devices arises when rubber components and cable sizes do not meet specified standards.

4. Shell integrity compromised due to cracks leads to a failure in maintaining explosion-proof qualities.
