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

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

Open switch device equipped with metal armoring consists of two parts: a fixed cabinet and a drawable part (handcart for short). The shell of open switch device equipped with metal armoring and the partitions of each functional unit are bolted by aluminum-zinc coated steel plates. The protection level of its shell reaches IP4X, and the protection level of each compartment partition board and circuit breaker door is P2X when it is opened. KYN28-12 type open switch device equipped with metal armoring can be equipped with VS1, ZN 12V type vacuum circuit breaker handcart and VD4 type vacuum circuit breaker handcart, and VC type vacuum contactor produced by ompany, which can be installed as double cabinets in parallel, that is, in back-to-back arrangement. The divece can be installed and debugged on the front, so it can be installed against the wall. The biggest advantage of installing against the wall is that it can save the floor space. In addition, it can be installed without the wall, that is, it is a double-sided maintenance type. The internal structure layout of the two is inconsistent, and its advantage is convenient maintenance.

 Shell and partition
The shell and partition of the Open Switch Device Equipped with Metal Armoring are made of high-quality imported aluminum-coated zinc steel plates which are bolted after being bent by CNC machine tools, so the assembled switch cabinet can maintain the uniformity in size. It has strong corrosion resistance and oxidation resistance, and has higher mechanical strength than the same steel plate. Switch cabinet is divided into handcart room (circuit breaker compartment), bus room, cable room and relay instrument room (low voltage room) by partition. The shell of each unit is independently grounded.
Product overview
The shell and partition of the Open Switch Device Equipped with Metal Armoring are made of aluminum-zinc coated steel plates or steel plates which are bolted after being processed and bent by CNC machine tools, so the assembled switch cabinet can maintain the uniformity in size. Aluminum-zinc coated steel plate has strong anti-corrosion and anti-oxidation effects, and has higher mechanical strength than the same steel plate. The switch cabinet is divided into handcart room, bus room, cable room and relay instrument room by partitions, and the shell of each unit has independent grounding. The doors of the switch cabinet are all sprayed with electrostatic plastic to make their surfaces have the advantages of impact resistance, corrosion resistance and beautiful appearance (color can be customized by users).
