Compression Grounding

HYGROUND ® Compression System Features and Benefits

The HYGROUND ® Irreversible Compression System (Continued) Features & Benefits • Irreversible compression system; meets NEC code, section 250 • Pure wrought copper extrusions, rod, and seamless tubing (identical material to the conductor), completely eliminates the possibility of galvanic corrosion due to dissimilar metals • Heavy duty connector designs; all connectors will carry the equivalent or greater current carrying capacity of the conductor while maintaining high mechanical strength and electrical integrity • Range take designs for a minimum number of connector combinations required to install a conductor range of #6 solid to 500 kcmil plus 1/2”, 5/8”, 3/4”, and 1” ground rods, and rebar; inventories are kept to a minimum and product selection is simplified • System engineered tooling; each tooling recommendation ensures reliability of the connection • Irreversible compression connectors can be installed in all kinsd of weather, eliminating costly delays and enables the installer to better schedule the job • May be installed without special training or special tools, the 750 Series of tools crimps the entire range providing a low installed cost with simplified installation • Each connection can be made in less than 3 minutes • Each connector is clearly marked with catalog number, conductor size, and installation die information for easy and accurate identification • Inspection ports are provided to assure proper insertion of the conductor for built-in quality assurance • The die index number is embossed on the connector after completion of the crimp facilitating speedy inspection of installed connectors to ensure consistantly reliable and sound connections

• Most HYGROUND ® irreversible compression elements are prefilled with PENETROX™ oxide inhibitor and individually sealed to keep all contact surfaces in the proper condition for installation as well as ensuring the electrical integrity of the finished connection by inhibiting moisture and contaminates from entering the contact area • All HYGROUND ® irreversible compression connectors are Listed in conformance with Underwriters Laboratories Standard UL467 and conform to applicable sections of the National Electrical Code; HYGROUND ® connectors may be used in direct burial or concrete embedded grounding applications • All HYGROUND ® irreversible connectors (with the exception of Types YGA and YGS) have been tested successfully according to requirements of Standard IEEE 837 meeting tough industry performance requirements • UPRECRIMP dies give added mechanical strength; UPRECRIMP34 is recommended for 3/4” rod; UPRECRIMP12 for 1/2” rod; and UPRECRIMP58 for 5/8” rod (now includes undersized U.S. marketplace rods) • HYGROUND ® connectors allow connection to most sizes of structural steel with no drilling, tapping, or welding — safely installed at low cost and hot work permits are not required to install in hazardous areas Please contact Customer Service for applications requiring IEEE-837 2014.
