Summary SectionThe name of the equipment that enables the assembly of electrical cables to any instrument (such as electrical panel-junction box-panel-various sensors-encoder-plug socket-electric motors-swicler etc.) by tightening the cable is called "Cable Gland".The cable gland ensures that the cable maintains the IP rating of the instrument as it enters the instrument.It prevents water and dust from entering the instrument.It ensures that the cable is fixed at the connection point and minimizes the arc formation caused by cable movement.“CABLE GLAND” must be produced according to the standards accepted in the world.UL514B – DIN EN 62444 , (DIN 40430 – EN 60423) Cable glands cable pull tests, buckling tests, IP water, dust tests, aging tests, flame retardancy tests and safe connection point device must be protected against external factors.Cable glands are made of polyamide-brass-stainless raw materials.Cable glands are divided into classes according to the environment in which they will work and external factors.Exproof-EMC-Polyamide – Stainless-in which environments which fittings will be used are stated below.Features: Raw Material : Polyamide 6 V2-V0 , Halogen free , Flame Retardant -

Combustible materials can be found in the form of gas, steam, smoke and dust.Three conditions must be met for fire or explosion to occur.If one of these three elements is disabled, the explosion hazard is eliminated.An atmosphere is defined as dangerous or explosive if there is a danger to human life or the environment.In the selection of electrical products that should be used in such dangerous environments, European Union countries have made it mandatory to use Atex certified products regarding Ex-proof materials.Cable Type (armored-non-armoured-swa-swg) Cable outer diameter, Mounting feature (empty hole / threaded), Mounting Diameter or Thread feature (metric-Npt-Gas-PG etc.), Ambient temperature, Ambient characteristics of the cables specified ATEX certified ex-proof cable glands are used at the input and output of the instrument.Ex-proof glands are determined according to the type of armored-unarmoured cable with double crimping, single crimping models.Double crimped ex armored cable glands are used in ex-d zone 0-1.After the first gasket compresses the cable surface, it is peeled off and the armor is compressed from the armor under the stripped cable with the ferrules inside the gland.The cable under the armor is also compressed from the lower gasket located in the lower body of the gland. The gasket (must be smooth and TPV-EPDM.) The lower gasket's duty is to fix the lower cable from the connection point of the device, thus making the connection of the terminals inside the device safer and provides additional IP protection.Non-armoured cable glands are different from normal glands because their inner gasket and retainer structures vary according to the exproof class.Thread length min 15 mm holder V0, silicone and Teflon are attached.All exproof unions are coded according to their class and product trees.Uncoded and uncertified products do not have exproof feature.The coding example and its classes are exemplified below.Standard : EN60079-0:2012, 60079-1:2007, 60079-31:2009,: EN 60529 IP66 / 68Usage areas: ZONE1, ZONE2, ZONE21, ZONE22 Gas Group IIA.IIB, IIC
