Standards
KYN28-12 type Open Switch Device Equipped with Metal Armoring meet the following standards:

1. 1. EC-298 2. GB3906-1991 3. DLVT404-1997 4. GB/T11022-1999

The sophisticated design of the Open Switch Device, fortified with metal armoring, comprises a robust fixed cabinet and a versatile drawable part, also known as a handcart. The shell and partitions of each functional unit are expertly crafted using aluminum-zinc coated steel plates, securely bolted for enhanced durability. Boasting a superior protection level of IP4X for its shell and P2X for its compartment partitions and circuit breaker doors when open, the KYN28-12 type Open Switch Device is engineered for excellence. It accommodates VS1, ZN 12V type, and VD4 type vacuum circuit breaker handcarts, alongside the VC type vacuum contactor. These can be configured as parallel double cabinets with a space-saving back-to-back arrangement. Installation and debugging are front-accessible, allowing placement against or away from walls. This flexibility not only conserves floor space but also enables double-sided maintenance, offering convenient upkeep advantages.

Shell and partition
The shell and partition of the Open Switch Device Equipped with Metal Armoring are meticulously constructed from high-quality imported aluminum-coated zinc steel plates. These components are precision-bent by CNC machine tools and secured with bolts, ensuring the assembled switch cabinet maintains uniform dimensions. Renowned for its outstanding corrosion and oxidation resistance, the material possesses greater mechanical strength than comparable steel plates. The switch cabinet is intricately divided into distinct compartments: handcart room (circuit breaker compartment), bus room, cable room, and a relay instrument room (low voltage room), with each unit's shell independently grounded for safety and reliability.
Product overview
The shell and partition of the Open Switch Device Equipped with Metal Armoring are crafted from premium aluminum-zinc coated steel plates or steel plates, precision-processed and bent by CNC machine tools. Bolted together, these ensure a uniform size for the switch cabinet. The aluminum-zinc coated steel plate offers superior anti-corrosion and anti-oxidation benefits, boasting higher mechanical strength compared to similar steel plates. The switch cabinet is strategically divided into handcart room, bus room, cable room, and relay instrument room by partitions, with each unit's shell independently grounded. The cabinet doors feature an electrostatic plastic spray, combining impact resistance, corrosion resistance, and a visually appealing finish, with customizable color options available for users.
