Enclosures are freestanding or self-supporting enclosures used to house electrical or electronic equipment. Cabinets are generally configured with doors, removable or non-removable side panels and back panels. The cabinet is an integral part of the electrical equipment and is the carrier of the electrical control equipment. It is generally made of cold-rolled steel or alloy. It can provide protection against water, dust, electromagnetic interference and other protective effects on stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets and so on.
