Distribution cabinet: product type of low-voltage distribution cabinet
GCS cabinet:
Main architecture
1: The main frame is made of 8MF open channel steel, and the side of the section steel is provided with assembly holes with a displacement coefficient of 20mm and 100mm and a hole diameter of 9.2mm

2: Each action room of the equipment is protected from each other, and its compartment is divided into action module room, bus duct room and cable room. The efficacy of each room is not related to each other.
3: The horizontal main bus duct adopts the method of horizontal arrangement behind the cabinet to improve the working capacity of the bus duct against electric driving force
The design of cable compartment makes it convenient for cables to enter and leave
Function module
The displacement coefficient of drawer cabinet floor height is 160mm, and the rated voltage of module control circuit is 400A and below
GCK cabinet: (MCC)
Main frame
GCK (L) low voltage distribution box

The basic structure of the box is an assembled structure. The foundation bolts are tightened and connected, and 20mm is the displacement coefficient. The function rooms of the hole mounting equipment are protected from each other. The main feature of GCK cabinet is that the bus duct is at the upper end of the cabinet door, and its compartments are divided into function module room (in front of the cabinet), bus duct room (at the top of the cabinet) and cable room (behind the cabinet). It is also assembled by the spectrum wall. At this time, the right side of the box is widened by 200mm as the cable room, which is similar to the top bus duct of MNS cabinet.
Function module
The displacement coefficient of drawer cabinet floor height is 200mm
MNS cabinet: (MCC)
Main frame
MNS type distribution box
MNS type distribution box
1: The basic structure of the box is composed of C-shaped aluminum profiles. The C-shaped aluminum profile is formed by bending thick steel plate with E = 25mm as the displacement coefficient array and holes
2: The pull-out MCC cabinet is divided into three compartments, which are divided into function module room (left side in front of the cabinet), bus duct room (rear side of the cabinet) and cable room (right side in front of the cabinet). Because the horizontal bus duct compartment is at the back, it can be made into two-sided cabinet.
3: In order to better reduce the order of high-voltage switchgear and broadband network, the rear group outgoing line is developed. The main bus duct of the high-voltage switchgear is horizontally installed at the top of the high-voltage switchgear. The rear half of the cabinet is the cable room. At this time, the bus duct style is similar to that of the GCK cabinet

PGL cabinet:
PGL type communication AC low-voltage distribution box is mainly used for power engineering customers such as power stations, substations, factories and mining enterprises. It is used as the driving force in the power distribution system with 50Hz communication AC, 380V rated working standard voltage and 2500A rated voltage. It is also used for power conversion, distribution and control of lighting fixtures and substation equipment. The product has high breaking capacity, and the rated value can withstand current up to 50kA in a short time.
This product complies with iec439 low voltage switchgear and control equipment, GB7251 low voltage switchgear and other specifications.
PGL distribution box is an indoor assembled, open type, two-sided maintenance distribution equipment. The main structure of the distribution box is composed of thick steel plate and angle iron by electric welding. There is a door in front of the counter. There is a car dashboard on the bank counter. It is an openable side door and can be equipped with a signboard. For side-by-side assembled cabinets, baffles are added between cabinets to reduce the possibility of expansion safety accidents due to common faults in a single cabinet. There is a main bus duct assembly sub insulation layer frame belt on the rear frame of the cabinet, and a bus duct protective cover is provided to avoid the malignant accident of short circuit fault of the main bus duct caused by falling metal materials. The neutral bus duct equipment is on the composite insulator at the lower side of the cabinet. The main grounding address of the maintenance grounding protection is welded to the lower side of the frame by electric welding. The instrument panel door is also connected with the shell by the grounding address.
PGL type communication AC low-voltage distribution panel is divided into: low-voltage measurement and verification cabinet, low-voltage three-phase five wire cabinet, reactive power compensation cabinet, municipal power generation transformation cabinet, bus duct connection cabinet and low-voltage outlet cabinet
