Compression Method Grounding Connectors Save 50-75% InTime and Labor Costs
This installation method results in a long last-ing low installed cost connection. You caninstall it ant forget it.Before compression, typical cable connectorcross section of cable and connector consistsof about 75% metal and 25% air. After Thomas& Belts method compression, the cross sectionshows 100% metal with virtually no air spaces.
Thomas & Betts introduces a system ofcompression method connections toreplace exothermic welding and itsassociated disadvantages. This com-pression method is designed to pro-vide quick, reliable connections forgrid grounding at significantly lowerinstalled costs since compression con-nectors install in less time, in anyweather, and are unaffected by mois-ture, reducing downtime. In addition,our compression connectors for gridgrounding require no special trainingfor installation. They are made of highconductivity wrought and cast copper,and are used for connecting and tap-ping cross grid, loop lines, and groundrods for direct burial or concreteembedded ground grid systems. TheThomas & Betts compression systemuses standard electrical connectorinstallation tools.
• Eliminates exothermic welding• Reduces labor and labor costs• Minimize possibility of poor
connections
Meets all applicablespecifications_________
Thomas & Betts grid and ground rodconnectors satisfy the requirements ofNEC 250-81 for connecting to theGrounding Electrode System. Theyalso meet the requirements of U.L. Std.467, U.L. Std. 486 CSA Std. C22.2 No.0.4 and CSA Std. C22.2 No. 65 beingacceptable as grounding and bondingequipment suitable for direct burial.Thomas & Betts grid and ground rodconnectors also satisfy the recom-mended practice for the selection ofgrounding connector joints describedin IEEE 837 standard for qualifyingpermanent connections used in sub-station grounding.The connectors conform to the follow-ing IEEE Standard 837 requirements:• 350°C current cycling• Freeze-thaw test• Accelerated aging - Nitric acid/salt
spray
• Mechanical, tensile and electromag-netic force (EMF) criteria
• Install in any weather - cut downtime• Enhance safety• Easy to install - no special training
The Thomas & Betts method, utilizingcompression tools with matching dies,forms the connector and conductorinto a solid, homogeneous mass toprovide an optimum electrical bondbetween connector and conductor.The dies are designed to produce acircumferential, hex-shaped compres-sion rather than a simple indent. Thecircumferential compression creates alarge area of high pressure contactbetween cable and connector which,in turn, assures high conductivity, lowresistance, and high pullout valuesexceeding all industry requirements.
