7-02 Description Anaconda IECEx-ATEX cable-hose-fi ttings The Anaconda IECEx-ATEX certifi ed cable-hose-fi ttings together with the Anaconda Sealtite conduits represent the ideal solution for the mechanical protection of cables and for the connection of equipment in a safe and explosionproof way. The temperature range of the standard version with an internal seal in EPDM is between -40°C and +100 °C, while the temperature range of the high temperature version with an internal seal in Silicone is between -70 °C and + 220 °C. The new barrier type with a 2 compound epoxy sealing has a temperature range from -60 °C till +130 °C. The Anaconda IECEx-ATEX cable-hose-fi ttings are also available in EMC version (shielded) for the connection of armoured cables. They are available either in nickel plated brass or in stainless steel AISI-316. The protection grade as delivered is IP66, but can be increased to IP 68 by using an additional fl at seal between body and enclosure (to be ordered separately). Classifi cation of explosion risk zones according to ATEX The Explosion risk zones are classifi ed based on a risk analysis, determining to what degree, a zone with presence of gas or dust has to be considered an explosion risk. · Zone 0 (Gas) and Zone 20 (Dust): place with continuous presence or long duration of an explosive atmosphere. · Zone 1 (Gas) and Zone 21 (Dust): place where during normal functioning an explosive atmosphere is occasionally present. · Zone 2 (Gas) and Zone 22 (Dust): place where an explosive atmosphere is impossible during normal functioning or that it is present only infrequently and for short periods. According to Directive 94/9/CE the equipment to be used in Ex-zones has to be certifi ed and ATEX marked. To this end the equipment is divided in groups and categories, according to the zones in which their use is consented. Group I = equipment for use in mining Hazardous Atmosphere Risk Zone Category Equipment Anaconda Atex System allowed Security level Mine Gas, Combustible Dusts Continuously or for long periods 0 I M1 No Very high (also safe in case of 2 independent defects) Mine Gas, Combustible Dusts Occasionally 1 I M2 Yes High (also safe in case of 1 defect) Group II = equipment for use in all other explosive atmospheres Hazardous Atmosphere Risk Zone Category Equipment Anaconda Atex System Security level Gases, Vapours and Mists Continuously or for long periods 0 II 1 G No Very high (also safe in case of 2 independent defects) Gases, Vapours and Mists Occasionally 1 II 2 G Yes High (also safe in case of 1 defect) Gases, Vapours and Infrequently or for Mists short periods 2 II 3 G Yes Normal (safe during normal functioning) Dusts Continuously or for long periods 20 II 1 D No Very high (also safe in case of 2 independent defects) Dusts Occasionally 21 II 2 D Yes High (also safe in case of 1 defect) Dusts Infrequently or for short periods 22 22 II 2 D II 3 D Yes Yes High (conducting dusts) Normal (non-conducting dusts) ANACONDA ATEX FITTINGS ENGINEERING DATA
