Kyn28-12 high voltage substation transformer cabinet
Kyn28-12 fixed enclosed switchgear (hereinafter referred to as switchgear) is a complete set of high-voltage electrical products of our company, which meets the requirements of national standard GB3906 "3-35kv AC metal enclosed switchgear" and dlt404 "technical conditions for ordering indoor AC high-voltage switchgear" of Ministry of electric power, and also meets the requirements of iec60298 "requirements for AC Jinli enclosed switchgear and control equipment above 1kV and below 52kv".
The product is small in size, only half of the volume of ordinary switch cabinet; the circuit breaker has the advantages of high reliability and good performance; the "five prevention" interlocking mechanism is reliable and simple. The switchgear is a 3.6 kV, 7.2 kV, 12kV three-phase AC 50 Hz single bus sectional indoor integrated device, which is used for receiving and distributing electric energy. It can be used in all kinds of power plants, substations, industrial and mining enterprises, high-rise buildings and other places. It can also be combined with ring main unit to be used in switching station.
