EXPLOSION-PROOF FRAMES IIGb / IIIDb FOR MODULAR DESIGN
When designing cabinets, situations arise where the dimensions of the existing enclosures are insufficient to accommodate the equipment. In this case, the cabinet can be divided into individual modules, connected either by metal sleeves or conduit. Using relatively small modules reduces the cabinet's dimensions, weight, and cost.
Furthermore, the large surface area allows for accessible cable glands, significantly simplifying installation. Modular cabinets are mounted on a frame /FRAME/ made of galvanized steel (cold or hot-dip galvanized), or, upon request, stainless steel.
The frames are manufactured for wall or floor mounting and are classified as friction-insincerely safe non-electrical equipment with explosion protection levels IIGb and IIIDb.
LOCATION OF EQUIPMENT INSIDE THE SHORVA BOXES...-O
Typical electrical components installed in the boxes include instrumentation and control devices, as well as any visual control equipment, including monitors and displays, video cameras, IT components, relays and timers, terminal cluminaires, fuses, etc. The electrical equipment and components supplied with the boxes are manufactured by leading manufacturers. Other equipment options can be supplied upon special request.
