Product Description

SHORVA is an explosion-proof terminal box with Ex d protection type made of aluminum. It is used for switching, distributing, and connecting electrical circuits in hazardous areas, including environments containing acetylene. The explosion-proof enclosure reliably contains any spark or explosion within the enclosure, preventing ignition of the external environment. It ensures easy installation and maintenance.

Advantages

Acetylene certified for extended use in the most hazardous areas
Die casting guarantees impeccable shape accuracy, free of internal stress and voids, as well as high homogeneity of the metal structure.
The aluminum housing shell combines exceptional mechanical strength, corrosion resistance and efficient heat dissipation.
SHORVA terminal boxes are included in the register of Russian industrial products.

LOCATION OF EQUIPMENT INSIDE THE SHORVA BOXES

Typical electrical components installed in boxes include terminal cluminaires, circuit breakers, residual-current devices (RCDs), residual-current circuit breakers, contactors, circuit breakers, fuses, ballast chokes, transformers, relays and timers, starters, IT components, remote-controlled switches, active/passive spark-proof barriers, and Ni-Cd batteries. The electrical equipment and components supplied with the boxes are from leading manufacturers. Other equipment options are available upon special request.

Explosion-proof boxes of the SHORVA type (explosion-proof enclosures)

EXPLOSION-PROOF FRAMES IIGb / IIIDb FOR MODULAR DESIGN

The use of a module of two or more explosion-proof SHORVA boxes allows solving problems where dimensions are required that exceed the maximum produced size of SHORVA explosion-proof boxes.

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.
