The Kopex-EXTM ISRTM Difference Gland Nut Chuck Ring * Fiber-reinforced nylon construction and unique over-molded design provide both strength and flexibility * Acts as a built-in clamp - superior 100% pull-out performance eliminating need for external clamping * Jaws grasp cable jacket over a large surface preventing damage and tearing * Flexible TPE belt positions the chucks radially, allowing uniform cable engagement Body * High-strength, corrosion-resistant copper-free aluminum construction (less than 0.4%) * Small turning radius allows close spacing of fittings * Fine thread for easy tightening; ample anti-seizing grease prevents "cold-welding" to gland nut threads * Anti-rotation splines prevent cable and bushings from twisting and deforming during tightening * Biting, box-side teeth ensure electrical ground with enclosure and allow draining of trapped moisture to prevent corrosion * O-ring seated in a recessed shoulder prevents over-compression of sealing bushing * Distinctive domed profile * High-strength, corrosion-resistant copper-free aluminum construction (less than 0.4%) * Heavy-duty, wide hex design for ease of installation * Smooth, snag-free contour design prevents injury and sheds water * Laser-etched certification markings are visible no matter where it is installed Sealing Bushing * High-tech silicon polymer performs in extreme temperature conditions (-50C to +110C) * Wide surface of engagement provides dependable seal against dust and liquids * Excellent engagement even on irregular cable shapes Interface Sealing O-Ring * Wide and flexible - adapts easily to variations in knockout dimensions * Wide sealing footprint to prevent moisture and dust from migrating into enclosure Kopex-ExTM ISRTM Fitting Meet 100% of cable pullout requirements with no need for external clamping Developed for the drill rig industry, with input from industry end users. Thomas & Betts is proud to introduce the next generation of globally-certified industrial strain-relief fittings: Kopex-ExTM ISRTM Fittings The latest in Thomas & Betts' long line of renowned industrial cable termination products, the Kopex-ExTM ISRTM fitting was developed in Canada with input from end users in the oil and gas industry. This is a high-level solution for industrial end users looking for a superior-quality fitting that reduces installation time and costs while surpassing global standards for pullout requirements. The majority of strain-relief fittings on the market today are designed to meet 25% of the IEC pullout requirements for surface applications and, as per IEC standard 60079, require that the installer provide additional clamping as close as possible to the point at which cables exit the enclosure to ensure that pulling and twisting is not transferred to the terminations. The external clamping requirement adds time, complexity and cost to the installation process. In the event that additional clamping is not provided, the integrity of electrical systems as well as compliance with IEC standards are compromised. With its unique design and integral clamping mechanism, the new Kopex-ExTM ISRTM fitting allows you to meet 100% of IEC cable pullout requirements with no external clamping, thereby reducing installation time, complexity and costs. Meet 100% of cable pullout requirements with no need for external clamping. Competition Kopex-ExTM ISRTM Fitting 25% pullout resistance External clamping required 100% pullout resistance No external clamping required Applications Tray Cable Complies with IEC requirements when used with enclosures containing no arcing or sparking devices. For enclosures with arcing or sparking devices, Kopex-ExTM ISRTM fittings must be used in combination with a certified Class I hazardous location sealing fitting. N.B. Tray cable is not suitable for use in Zone 1 locations. Portable Cord Complies with IEC requirements when used with enclosures containing no arcing or sparking devices. For enclosures with arcing or sparking devices, Kopex-ExTM ISRTM fittings must be used in combination with a certified Class I hazardous location sealing fitting. Portable cord can be used in Zone 1 applications only when installed on portable equipment. Utilization For use with unarmored cable types suitable for use in Class I, Zone 1 (e.g. Extra Hard Usage Cord). When used with tray cables, Series ISRTM cable glands are suitable to be installed in Class I, Zone 2/Div. 2 classified hazardous location area according to CEC/NEC wiring method, or subject to local inspection authority having jurisdiction. NEC or USA requirements For installations in accordance with the NEC in Class I Zone 1, the ISRTM fitting can be used only with listed extra-hard usage cord or listed TC-ER-HL cable having a diameter up to and including 1 inch. Additionally, for Zone 20 applications, only extra-hard usage cord can be used. Refer to NEC wiring methods for additional details and local inspection authority for more information.
