4.6.1 Non-metallIc sheathed cables
The smaller sizes of non-metallic sheathed cables arc usually gripped directly by the conductors by forming them into a loop to which the pull wire or rope can be attached. The insulation on each conductor is removed before the loop is formed. Larger sizes are more easily handled by applying a pulling grip over the cable or cables, provided the pull is not too severe.
If more than one cable is involved, the ends should be bound together with friction tape before applying the grip overall. Long. hard pulls will necessitate the use of pulling eyes.
4.6.2 Lead sheathed cables
Pulling eyes for lead sheathed cables can be applied either at the factory or in the field. They must be wiped or sealed by other suitable means to the lead sheath to prevent the entrance of moisture. For shorter pulls a basketweave grip may be applied over the lead sheath or over the jacket if one is present over the lead sheath.
4.6.3 Metal clad cables
In pulling metal clad cable it is necessary to grip the armor and the conductors. This can be accomplished in a number of ways. One method requires that a portion of the armor be removed. Friction tape is then applied over the armor and down over the conductors, and a long hasketweavc grip is applied in such a way that it grips both the armor and the conductors. Another method requires that two holes be drilled through the cable annor and conductors) at right angles to each other and that a loop be formed by passing steel wires through the holes and out over the end of the cable. A third approach would be to use a pulling eye and a grip together. the grip being applied over the armor to prevent its slipping hack. The armor is not a tension member. Be certain pulling load is taken by the conductors.
5. Sidewall pressure
The sidewall pressure in general is expressed as the tension out of a bend expressed in newtons (pounds) divided by the inside radius of the bend expressed in meters (feet). Equation 5 is for one cable. Equations Sa and 5b are for the “worst ease” condition with three single cables.
