KYN28-12 indoor metal armoring movable switch cabinet

Features
  • Sufficient air insulating distance to avoid the probability of inter-phase accident.
  • The protection grade of shell is IP4X to better prevent human body and external solid from approaching to the live part and ensure personnel safety and reliable operation of equipment;
  • The key parts of large current equipment is made of non-permeability magnetic material to reduce the eddy-current loss effectively.
Applicable place
  • Power transmission of power plant and small/medium-sized power generator, power distribution of industrial and mining enterprises, power receiving and distribution of secondary substation of power system and start of large-scale high voltage electric motor.
