Product Introduction

The switch cabinet is designed according to GB3906-91 and IEC298 standards for armored metal-enclosed switches. The whole is composed of two parts: the cabinet and the withdrawable part (handcart). The cabinet structure is processed by CNC and bolted to form a combination. The inside of the switch cabinet is divided into the circuit breaker room, the main busbar room, the cable room and the relay instrument room with a metal partition. The enclosure protection level reaches IP3X, the protection level of each compartment is IP2X, and all metal structural parts are reliably grounded, and each compartment of the main circuit system has an independent exhaust pressure release channel.

Standards
