XL series power distribution cabinet cabinet structure is made of high quality cold-rolled steel plate or stainless steel, which is processed by CNC machine tools by bending welding or bolt assembly. The cabinet structure is processed by powder electrostatic spraying process, which has the characteristics of anti-corrosion and salt spray.
XL-type power distribution cabinets adopt new electrical components, which have the characteristics of compact structure, convenient maintenance, and flexible wiring schemes. In addition to being equipped with air circuit breakers and fuses as a short-circuit protection function, the distribution cabinet can also have over-voltage, under-voltage, and phase-loss alarm functions. The front door of the cabinet can also be equipped with monitoring instruments, operation buttons and indicators according to design requirements.
The installation method of electrical components is beam type or plate type; the system scheme is flexible, easy to install, versatile, and easy to maintain and repair.
According to the change of the primary circuit plan, it is necessary to add the necessary door plates, sealing plates, partitions, installation supports and busbars to form a complete switch cabinet. Doors and cabinets are connected to PE bars with copper conductive tape and yellow-green two-color wires. The door lock is securely connected to the door by a grounded protective washer.
XL distribution cabinets are available in indoor and outdoor types. According to customer requirements and combined with the specifications of the incoming and outgoing cables, reserve the entry and exit holes in the appropriate position of the distribution cabinet to facilitate field construction wiring.
