2 Eliminates exothermic welding Reduces labor and labor costs Minimize possibility of poor connectionsThomas & Betts introduces a method of compression to replace exothermic welding and its associated disadvantages. This compression method is designed to provide Quick , reliable connections for grid Grounding at significantly lower installed costs becausecompression Connectors install in less time, in any weather, and are unaffected by moisture,reducing downtime. In addition, our compression Connectors for grid Grounding require nospecial training for installation. They are made of high-conductivity wrought and cast copper,and are used for connecting and tapping cross grid, loop lines and ground rods for direct burial or concrete embedded ground grid systems. The Thomas & Betts compression system usesstandard electrical connector installation all applicable specificationsThomas & Betts grid and ground rod Connectors satisfy the requirements of NEC 250-50 for connecting to the Grounding Electrode System.

3 They also meet the requirements of UL Std. 467, UL Std. 486 CSA Std. No. 41 and CSA Std. No. 65 being acceptable as groundingand bonding equipment suitable for direct burial. Thomas & Betts grid and ground rod Connectors also satisfy the recommended practice for the selection of Grounding connector joints described in IEEE 837 standardfor qualifying permanent connections used in substation Connectors conform to the following IEEE Standard 837 requirements: 350 C current cycling Freeze-thaw test Accelerated aging nitric acid/salt spray Mechanical, tensile and electromagnetic force (EMF) criteria Install in any weather cut downtime Enhance safety Easy to install no special trainingReliable installations throughcompression connectionsThe Thomas & Betts method, utilizing compression tools with matching dies, forms the connector and conductor into a solid, homogeneous mass to provide an optimum electrical bond between connector and conductor.

4 The dies are designed to produce a circumferential, hex-shaped compressionrather than a simple indent. The circumferential compression creates a largearea of high-pressure contact between cable and connector which, in turn,ensures high conductivity, low resistance and high pullout values exceedingall industry installation method results in a long-lasting low installed cost connection. You can install it and forget compression, typical cable connector cross section of cable and connectorconsists of about 75% metal and 25% air. After Thomas & Betts method compression, the cross section shows 100% metal with virtually no air Method GroundingConnectors save 50 75% in timeand labor Grounding ConnectorsC-53 United StatesTel: : ServicesTel: Grounding ConnectorsGroundingThomas & Betts offers its complete line of grid-ground compressionconnectors. Our E-Z-Ground Connectors are designed for direct burial andoffer a safe, efficient alternative to exothermic welding products.

5 Grid groundinstallations do not require explosive charges, and can be installed in variousclimate conditions. These range-taking products will reduce the number ofconnectors and dies needed for your installation. Thomas & Betts E-Z-Ground products meet all applicable standards(IEEE837, UL467, CSA ).
