Installation Method
The silicone self-locking overhead line cover can be installed directly onto energized or de-energized conductors depending on operational procedures.
Position the cover along the exposed conductor.
Close the self-locking structure along the conductor surface.
Ensure the cover is securely locked and fully covering the conductor.
Installation is quick and does not require flame heating or special tools.
