How to Install a 600/900 AMP Deadbreak Bushing Extension

This guide provides instructions for the safe installation, connection, and grounding of a 600/900 AMP Deadbreak Bushing Extension, including proper cleaning, lubrication, and torquing procedures for various mating components.

Estimated time: 1h

Tools needed:

Torque wrench, ELASTIMOLD 600SW spanner wrench (if applicable), 600-AT (if applicable), 600ATM (if applicable), Suitable hex tool (if applicable), Wire strippers

Supplies needed:

Bushing Extension, Lubricant (supplied or ELASTIMOLD approved), Double ended stud, Mating electrical connector/plug/well, Compression lug (if applicable for rubber connecting plug), Insulating plug (if applicable for rubber connecting plug), Protective cap (if applicable), #14 AWG copper wire or equivalent, Suitable ground connector

  1. Ensure Safety and Prepare Components

    Before beginning, ensure all apparatus are de-energized. This product must be installed only by competent personnel trained in high voltage electrical equipment. Inspect all parts for damage, proper rating, and compatibility with mating components. Remove any protective shipping covers from the bushing extension.

  2. Clean and Lubricate Bushing Extension Interface

    Remove protective caps from the bushing extension. Thoroughly clean the entire bushing extension interface and lubricate it with the supplied or ELASTIMOLD approved lubricant. Ensure all mating surfaces remain clean.

  3. Connect and Hand-Tighten Mating Product

    Clean the interface of your chosen mating product (e.g., connecting plug, deadend plug, reducing tap plug, reducing tap well, or elbow tap plug) and lubricate it with the supplied or ELASTIMOLD approved lubricant. Finger tighten the supplied double-ended stud into this mating product. Carefully insert the assembled product into the bushing extension, engage the threads, and hand-tighten the connection.

  4. Torque the Assembly to Specification

    Using a torque wrench, tighten the assembly. For Insulating Plugs, torque to 50-60 foot-pounds. For Epoxy Connecting Plugs, Reducing Tap Plugs, or Tap Wells, use an ELASTIMOLD 600SW spanner wrench and torque to 40-48 foot-pounds. For Retainer Sleeve/Pin Contacts, use a 600-AT and torque to 50-60 foot-pounds with a suitable hex tool. For Elbow Tap Plugs, use a 600ATM and torque to 50-60 foot-pounds. For Rubber Connecting Plugs, temporarily install a compression lug and insulating plug, then torque the insulating plug nut to 50-60 foot-pounds. Hold the compression lug to prevent loosening when removing the temporary components.

  5. Complete Mating Component Assembly

    Clean and lubricate any remaining interfaces of the connected plug or well. Assemble any additional appropriate mating components according to their specific instructions. If using an insulating plug, assemble its provided protective cap as per its instructions.

  6. Ground the Bushing Extension

    Connect a short length of #14 AWG copper wire or equivalent to the grounding eye of the bushing extension, forming a small, tight loop without damaging the eye. Securely connect this wire to ground using a suitable connector. Any mating components requiring a ground should also be connected in this manner.
