High Voltage Complete Power Distribution Cabinet / Switchgear For Industrial Mining Enterprises
Product Description
The KYN28A-12 type AC metal-encased with drawable switchgear is a three-phase AC 50Hz, rated voltage 3-12kV, single busbar and single busbar section system indoor complete switchgear. It is mainly used for power receiving and power distribution in power plants, substations, community power distribution, and industrial and mining enterprises' power distribution devices. It can also be used for starting control of high-voltage motors and is capable of achieving control, protection and detection of circuits. The switch cabinet can be equipped with imported brands such as VD4, EV12, HXV, AV3, etc., or domestic famous brands such as VS1, VEP, VBG, ZN73A.
All the products are custom-made. Before placing the order, please communicate in detail with the customer service about your
specific requirements (such as specifications, parameters, functions, etc.). We will provide an exclusive solution based on your
needs and confirm the price. The production cycle of custom-made products depends on the complexity of the order. Thank you for
your understanding and cooperation!
