KYN28

The KYN28‑12 armored, withdrawable AC metal‑enclosed switchgear is an indoor, complete distribution device designed for three‑phase AC systems operating at 50 Hz, with either a single busbar configuration or a double busbar sectionalized arrangement. It is suitable for power systems with a rated voltage of 12 kV and represents the most widely used core cabinet type in China's 10 kV distribution networks. It is commonly deployed in urban grid substations, plant auxiliary power systems, distribution rooms of large industrial and civil buildings, and main step‑down substations of industrial and mining enterprises. The equipment can handle incoming and outgoing feeders, transformer protection, and high‑voltage motor control, making it well suited for applications involving frequent operations as well as unattended operation scenarios.

MNS

The MNS-type low-voltage withdrawable switchgear (hereinafter referred to as the switchgear) is an advanced low-voltage switchgear developed through the adaptation and improvement of the foreign MNS series, in response to the evolving needs of the power industry. This product complies with the national standards GB 7251, VDE 660, and ZBK 36001-89 "Low-Voltage Withdrawable Switchgear Assemblies," as well as the international standard IEC 439. The MNS-type low-voltage switchgear meets a wide range of power supply and distribution requirements and is extensively applicable to various low-voltage distribution systems, including those found in power plants, substations, industrial and mining enterprises, commercial buildings and hotels, and municipal infrastructure projects.
