KYN28A-12 Armored Central AC Metal-Clad Switchgear

1. Product Description

KYN28A-12 Armored Central Metal-Clad Switchgear (hereinafter referred to as switchgear) is a new type of product independently developed by our company based on absorbing advanced manufacturing technologies both domestically and internationally. It can replace various old metal-clad switchgear and is suitable for three-phase AC 50 Hz 3.6-12 kV power networks. It is used for receiving and distributing electrical energy, as well as for controlling, monitoring, and protecting circuits. It can be used for single busbar, single busbar sectional system, or double busbar system.

The distribution equipment complies with standards including IEC298 Metal-enclosed switchgear and controlgear for rated voltages above 1 kV and including 12 kV, IEC694 Common clauses for high-voltage switchgear and controlgear standards, Chinese GB3906 AC metal-enclosed switchgear for rated voltages from 3.6 kV to 40.5 kV, DL404 Ordering specifications for indoor AC high-voltage switchgear, and German DIN VDE0670 AC for rated voltages above 1 kV. It is also equipped with perfect and reliable anti-malfunction features.
