Product Introduction

Product features:

Wide applicability, easy to implement various schemes, and meet the needs of different users. Good interchangeability of the truck, making movement within the cabinet labor-saving and smooth. Excellent main circuit insulation, resulting in a compact switchgear structure and saving floor space. Various operations of the switch can be performed with the high-voltage room door closed. The cable room is spacious and can connect multiple cables. Reliable grounding switch operation makes maintenance work safer. Fully metal armored enclosure, with an exterior protection rating of IP4X when the door is closed and IP2X when the truck room door is open, ensuring personal safety.

Application range:

The KYN61-40.5 switchgear is designed according to the armored metal-enclosed switchgear standard GB/T3906. It is suitable for a three-phase AC system with a rated voltage of 40.5kV and a rated frequency of 50Hz. It is used for receiving and distributing electrical energy and performing control, protection, and monitoring of circuits. It is widely used in general power systems and can also be used in areas with frequent operations.
