What is the difference in failure mode between voltage-limiting SPDs and switching SPDs? Sep 30 , 2025
Failure modes of voltage-limiting SPDs (varistors) As a core component of voltage-limiting SPDs, varistor (MOV) failure modes primarily stem from the material's physical properties and electrical stress. The primary failure mode is short-circuit failure and its derivative thermal breakdown. When subjected to surge currents exceeding their tolerance (a single, large energy event or multiple, cumula...

Protecting the "nerve endings" of the intelligent era: Your data security is far more fragile than you think Oct 24 , 2025
We've equipped core computer rooms and power distribution facilities with sturdy lightning-proof enclosures. However, the network cables, signal cables, and data cables scattered throughout the system are like the "nerve endings" of intelligent systems. While seemingly insignificant, they carry the critical mission of information transmission. Once these "nerve endings" are damaged, the entire int...
