Selection of DCS cabinet doors
Thread Content
Currently, the front and rear doors of DCS cabinets are made of metal; can glass doors be used instead? Some electrical cabinets do use glass doors – are there any mandatory regulations regarding this?
Those with glass doors usually have a display panel inside; DCS systems rarely have such a feature, as it’s completely unnecessary.
The DCS cabinets do not have glass doors
There are no regulations specifying that cabinet doors should be made of aluminum or steel; they are usually double-door on opposite sides, and there is absolutely no need to use transparent glass material for them. . . It’s like those desktop PCs with glass transparent casings nowadays – they’re not very useful, unless you want to see the internal electronic display panels. . . It’s sufficient to leave space for opening the doors at the front and back of the cabinets; the doors are opened for debugging purposes, while they remain closed in normal times. Additionally, in terms of the doors that lead between cabinets, these are also kept closed most of the time. Ordinary workers are not allowed to enter the cabinet area under normal circumstances, as the entire area is enclosed – so what’s the need for transparent doors? . .
In fact, fully metal enclosures can also provide electromagnetic shielding, reducing external electromagnetic interference.
How has DCS ever seen cabinet doors that are not made of metal?
The distribution cabinets with glass doors mentioned by the poster are mostly simple control button boxes that contain contactors for low currents; proper GGD distribution cabinets do not have glass according to standards. DCS systems, in order to prevent interference, require fully metal enclosures
Metal cabinets are more suitable for on-site needs; there are probably a great many metal cabinets in use
