CPI ™ Connector Products Ground Grid Connectors CPI ™ Ground Grid Connectors Accommodates .679” - .813” Diameter Range (Vertical) .368” - .813” Diameter Range (Horizontal) CPI Ground Grid Connectors are a safe, fast, and dependable method of making permanent wire-to-wire and wire-to-rod connections for a variety of grounding applications. Using a special shear-head bolt to drive a wedge into the connector activates the connector. When the proper torque and spring tension is achieved, the bolt head shears off, giving the installer a positive indication of an optimum connection. Features and Benefits • No special molds, chemicals, tools, dies or fired-on charges necessary for installation; installed with a common socket, impact or ratchet wrench • No temperature or weather restrictions for installation; can be installed no matter what environment exists at the job site • Shear-head bolt ensures consistency of application and positive verification of a completed connection • Fully tested to IEEE standard 837 for: • Mechanical Pullout • Electromagnetic Force • Current-Temperature Cycling • Freeze-Thaw • Corrosion-Nitric Acid • Fault Current, 35 kA rms. sym. at .02 sec. • Thermal Shock and Accelerated Corrosion • Typical applications: • Substation ground grids • Pole grounds transmision line grounding • Industrial/Residential service grounds • Pad Mount Transformers • Telco distribution / CATV grounds • Wind Farms
