How to Install the K656DR/K676DR Deadbreak Insulated Cap
This guide provides step-by-step instructions for safely installing the K656DR and K676DR deadbreak insulated caps on 15kV and 28kV class deadbreak bushing interfaces, ensuring proper grounding and connection.
Tools needed:
Hotstick tool, High impedance testing device
Supplies needed:
K656DR or K676DR Insulated Cap, Lubricant, Stud (if applicable), No. 14 AWG (2.5mm2) copper wire, Grounding wire connector
- Verify De-energized State
DANGER: All apparatus must be de-energized during installation. Remove the voltage detection point cap from the deadbreak elbow connector using a hotstick, peeling it off at an angle. WARNING: Use a specially designed high impedance testing device for capacitive test points; do not use conventional voltage measuring equipment. Follow the meter's directions. Treat the elbow as energized until the 'no voltage' indication is confirmed by other means. After testing, clean and lubricate the inside surface of the cap with lubricant and replace it on the test point.
- Prepare Grounding Wire and Stud
Insert a length of No. 14 AWG (2.5mm2) copper wire through the grounding eye of the insulated cap. Form a small loop and twist it tight, taking care not to damage the grounding eye. Connect the free end of the grounding wire to the system ground using a utility-specified connector, ensuring sufficient length. If the bushing is not equipped with a stud, hand assemble the supplied stud into the insulated cap; otherwise, discard the supplied stud.
- Clean and Lubricate Interfaces
For new installations where the bushing is known to be de-energized, thoroughly wipe both the bushing interface and the insulated cap interface clean of all contaminants. Lubricate these cleaned surfaces with the supplied lubricant or an Elastimold approved lubricant. For circuits previously energized, clean and lubricate only the interface of the insulated cap.
- Install the Insulated Cap
WARNING: A second hotstick will be required to control the grounding wire during installation. Attach the first hotstick tool to the pulling ring of the insulated cap and push the receptacle onto the bushing interface as far as it will go. Using the second hotstick, engage the grounding wire and establish slight tension, wrapping the wire loosely around the center of the insulated cap body. While pushing against the bushing interface with the first hotstick, twist clockwise until threads engage. Continue turning clockwise without pushing until resistance is felt. DO NOT OVERTIGHTEN.
