ABSTRACT:
Long lengths of large diameter electric cable can be laid in underground ducts by supporting each cable to be laid in the duct on its own rotatable reel, introducing the cables simultaneously and separately from the reels to the duct, lubricating the cables, and pulling the cables simultaneously through the duct. A guide is used for introducing the cables into a conduit such as the duct and lubricating the cables. The guide comprises a body portion sized to fit within the conduit, the body having a plurality of longitudinal channels along its periphery for forming a plurality of spaced-apart cable guide passages in cooperation with the internal wall of the conduit. A lubricant can be introduced into each channel.
