Hot rolling & Cold rolling steel

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets. If these...

EMC Environment

Assemblies can emit and the must be immune to external  electromagnetic disturbances. IEC defines two categories    a) Environment A - relates to low-voltage non-public or industrial  networks / locations / installations including highly disturbing sources.    b) Environment B - relates to low-voltage public networks such as  domestic...

Internal Arc inside Switchboard

Arc Proof metal-clad switchgear and controlgear is designed and manufactured to prevent the occurrence of internal faults. If the switchgear and controlgear is installed, operated and maintained following the instructions of the manufacturer, there should be little probability that an internal arc occurs during its entire service life, but it cannot be completely disregarded...
