D. A nonfreezing type of swivel, or swivel connection, shall be inserted between the pulling rope and the cable pulling eye, grip, or loop to prevent twisting under strain and to allow for free rotation of the cable during pulling.

E. Cable pulling compounds shall not contain microball spheres, ethylene glycol or mineral oil. Acceptable pulling compound shall be as manufactured by American Polywater Corp. (Polywater J) or FFGD approved equal.

F. As soon as the cable is pulled into place, the pulling eyes, cable grips, or pulling loops shall be removed. Any cable which was scaled shall be resealed.

1. Cables pulled with ends pulled to a point above normal grade elevation shall be resealed with a minimum of three (3) wraps of 2” Scotch #23 (or FFGD approved equal) rubber splicing tape. Exposed cables ends shall be carefully wrapped in such a manner as to prevent unintentional water entry from weather exposure. Exposed cable ends shall be wrapped prior to the end of the work day.

2. Cables pulled with ends pulled to a point below normal grade elevation (manholes or vaults) shall be resealed with appropriately sized RayChem heat shrink end seal boots. Exposed cables ends shall be sealed in such a manner as to prevent unintentional water entry from weather or water filled manholes or vaults. Exposed cable ends shall be sealed prior to the end of the workday.

Whenever the capacity of the pulling mechanism exceeds the recommended pulling tension of the cable as given by the cable manufacturer, a dynamometer shall be used to show the tension on the cable and the indicator shall be constantly watched. If any excessive strain develops, the pulling operation shall be stopped at once and the difficulty determined and corrected.

3.09 Sidewall Pressure:

A. To avoid insulation damage from excessive sidewall pressure at bends, the pulling tension in pounds at a bend shall not exceed 300 times the radius of the bend in feet.
