New Cortem Group REV and REVD series cable glands for ATEX and IECEx applications
19 September 2013
The new REV and REVD series cable glands are suitable for use in hazardous areas where there is a danger of explosion. REV enables the insertion of non-armoured cables and REVD armoured cables into explosion-proof junction boxes, lighting fixtures, plugs and sockets, etc...
The new cable glands series have optimally exceeded all the tests currently required for the certification of this product. The result is a cable gland of the highest performance in terms of reliability and safety, able to cover a wide range of main cables such as plaited armoured cables, flat or wire cables with armour thickness from 0 to 2,5 mm.
REV and REVD series are more competitive and, at the same time, more powerful than the cable glands of the previous series.
The most important innovation is the use of one sealing ring on the inner and outer sheath of the cable and no longer a kit of sealing rings of different diameters. REV series is constituted by a single sealing ring which tightens the incoming cable ensuring the 'Ex d' way of protection. REVD series has a second sealing ring that tightens on the outer sheath of the cable to ensure the IP66/67 degree of protection avoiding the ingress of water, moisture, rain and dust. The cable range available for each cable gland is described in the following tables.
A further advantage is the lighter weight and the smaller dimensions, an important detail when there’s the need to install a large number of cable glands on explosion-proof enclosures.
The new cable glands REV and REVD series have been designed to replace FL/FG e FAL/FGA series cable glands in NICKEL-PLATED BRASS, STAINLESS STEEL and GALVANIZED STEEL from 3/8" up to 2" included. From 2” 1/2 to 4” sizes, FL/FAL series will remain available until the certification is completed.
This new series includes also REVL, REVDL series special version which can accommodate smaller cable diameters than the standard required for each measure. In this way, the use of reductions is avoids.
The new cable glands of REVF and REVN series are designed to replace the FGF series (female threaded entry) and the FGN series cable glands (male threaded entry) available from 3/8" to 2" sizes and made ??of NICKEL-PLATED BRASS, STAINLESS STEEL and GALVANIZED STEEL.
They are provided with high-tech and high mechanical performance compression rings and gaskets with high-temperature resistance.
Thanks to their structure, they are particularly suitable both in harsh application, such as marine one, and places subjected to stress, vibration, mechanical shock as often happens in all those places of the “heavy” industry where safety is a top priority.
The new series has three type of protection 'Ex d', 'Ex e' and 'Ex tb'. The evolution of the marking has allowed us to create a transparent polyester label which has stood very well the various tests of salt corrosion, durability in harsh environments and high temperatures, impact resistance.
In order to ensure a greater security and reliability of its cable glands, Elfit, in addition to mandatory certification tests, submits its products to further harsher tests. It evaluates the resistance of its cable glands to a traction test without fixing the cable armour and with much higher load values ??(up to an extra 50%) than required by the standard.
