Qingdao hengfengyou electric, subordinate to hengfengshuai group, is a professional electrical company focusing on the production, manufacturing and sales of electrical distribution products. It has been successfully sold to more than 50 countries around the world. Today, let Xiaobian show you the number and model of common distribution boxes:
Small distribution boxes are generally divided into compact distribution boxes, such as pz30 or golf. They are commonly used for concealed installation in Residential Suites or corridor walls. They are often composed of miniature circuit breakers. The incoming line is 3-phase MCB below 63A, and the outgoing line is 3-phase or single-phase MCB or RCB. They are generally embedded in the wall, and the bottom distance from the ground shall not be less than 1.5m according to the specification requirements. The surface mounted distribution box is often used as the floor general distribution box, and the lower level is the above compact distribution box. The general distribution box is often set in the strong current shaft. The surface mounted, the main switch is the high current molded case circuit breaker MCCB, the outgoing line is MCCB or MCB (medium current, three-phase majority), the incoming line is generally cable, and the outgoing line is the conductor to the concealed distribution box at the lower level, and the model is generally XM The cabinet type distribution box is generally floor mounted and used as the main incoming line. The general model of electric box has little meaning. It mainly depends on the switch.

Give an example
GCK the first g represents the distribution cabinet, the second C represents the drawer type, and the third K represents the control
GGD the first g represents the distribution cabinet, the second g represents the fixed type, and the third D represents the power
What does distribution box 1la1a 1al1b at-dt mean, and 1ap2 2ap1 3apc 7ap 1kx and so on.
This is the common code of each distribution board in the engineering distribution system diagram, which is arranged by the designer without mandatory specifications. However, following certain rules, Al is the distribution box, AP is the power distribution box, KX is the control box, etc. For example: 1al1b - type B distribution box representing one location on the first floor; At-dt - elevator distribution box; 1ap2 - represents the power distribution box at the second position on the first floor.
