How to Install the 373FTV Feed-Thru/Junction Device
This guide provides instructions for the safe installation and initial setup of the ELASTIMOLD 373FTV Feed-Thru/Grounding Device, detailing its use as a junction point for 35kV class loadbreak connectors. It also outlines the initial steps common to its use as a grounding point.
Estimated time: 1h
Tools needed:
Hotstick (live-line tool), Screwdriver
Supplies needed:
Electrostatic grounding lead (No. 14 copper wire or equivalent), Silicone grease (supplied with product), Mating 35kV class loadbreak connectors
- De-energize and Ground the System
Before beginning installation, ensure all apparatus is de-energized. This product must only be installed by competent personnel trained in good safety practices involving high voltage electrical equipment. Insert an electrostatic grounding lead (No. 14 copper wire or equivalent) into the grounding lug provided on the mounting hardware and tighten the lug. Connect the opposite end of the lead to a reliable ground, leaving sufficient slack to operate with a hotstick. Keep the ground wire clear from operating interfaces.
- Prepare the Feed-Thru Bushings
Remove the protective covers from the bushings of the feed-thru. WARNING: Protective covers must not be on the bushing of the feed-thru when the feed-thru is energized. Clean the bushing surfaces thoroughly and lubricate them with the supplied silicone grease. Do not substitute other lubricants, as they may be harmful to this product and its mating product(s).
- Mount the Feed-Thru onto a Parking Stand
Firmly attach the feed-thru eye to a hotstick. Using the hotstick, slide the feed-thru onto a parking stand. Unlock the hotstick and back off, allowing space for the eyebolt to be tightened. Tighten the eyebolt by rotating the hotstick clockwise until snug, but do not overtighten. Release the hotstick.
- Connect the First Loadbreak Elbow
Following the applicable operating instructions (IS-375/376LR), remove one loadbreak elbow from its apparatus bushing insert and carefully place it onto one of the feed-thru interfaces using a hotstick.
- Connect the Second Loadbreak Elbow (Junction Point)
For a junction point application, following the applicable operating instructions (IS-375/376LR), remove the second loadbreak elbow from its apparatus bushing insert and place it onto the remaining feed-thru interface using a hotstick. The 373FTV is now configured as a junction point. To reconnect the elbow(s) to the apparatus bushing(s) later, first make certain no faults exist on the system, then reverse the operational sequence following the applicable loadbreak-loadmake operating instructions.
