Explosion-proof equipment plant
SHORV-N explosion-proof stainless steel boxes are stationary devices that are intended for operation in hazardous areas and arrangement of electrotechnical components, such as terminals, control, signaling elements, etc. at the enterprises of food, chemical, oil and gas and other infustries.
The type of explosion protection - flameproof joint. At the design stage, the enclosures undergo mathematical modelling and tests in order to ensure the conformity to declared explosion protection markings.
Solid cast explosion-proof enclosures of SHORV-N series are approved by the Russian Maritime Register of Shipping and are suitable for application on ships and at the facilities supervised by the maritime register. The enclosures have the certificate of the Customs Union and IEC Ex international certificate.
- Seamless enclosure and technology of molding allows producing an enclosure of increased non-deforming geometrical accuracy and achieve parameters required for explosion protection class IIC (except acetylene atmospheres).
"Х" sign specified after Ex marking indicates that is is prohibited to use the device in explosive mixtures of acetylene and air.
Scope of application - outdoor and indoor hazardous areas, as per explosion protection marking - category II for gas subgroup IIA, IIB, IIB+H2; category 1, 2; category III for dust IIIA, IIIB, IIIC, zones 21, 22; category I for firedamp and dust РВ, РП, zones 1, 2; mines and pits non-hazardous with gas (methane) and coal dust; areas non-hazardous with dust and gas.

Main types of terminalsIIGb / IIIDb EXPLOSION-PROOF FRAMES FOR MODULAR VERSION
When designing cabinets there are situations where dimensions of enclosures are not sufficient to arrange the equipment. In this case the cabinet may be divided into separate modules connected either by metal hoses or by pipe conduit.
Application of relatively small modules enables to reduce the dimensions, mass and cost of the cabinet. Moreover, large surface areas enable to arrange cable glands in accessible places which significantly simplifies the mounting.
Modular cabinets are installed on the frame /RAMA made from galvanized steel (cold or hot-dip galvanizing) or stainless steel upon request.
Frames are manufactured for wall or floor mounting and are frictionally intrinsically safe non-electrical equipment with IIGb and IIIDb level of explosion protection.
MECHANICAL PROCESSING OF SHORV-N BOXES
Wall and cover thickness of SHORV-N explosion-proof enclosures is sufficient to manufacture threaded holes for connection of various types of explosion-proof cable glands, control and indicating elements. There is a wide range of control, indicating and signaling elements of standard version, elements and modules for specific tasks, as well as elements of typical version upon customer’s request. Big size of control elements of M series enables to work in gloves, indicating elements have large diameter – 40 mm and are equipped with a reflector which makes the signal clearly visible at large viewing angle and various degrees of surface dirtiness. Operating handles for circuit breakers are selected depending on number of poles and circuit breaker type. Handle’s axle length can be adapted to the type of circuit breaker and size and type of the explosion-proof enclosure.
