Mechanical lugs or compression lugs can be used as stated above. When using the different types of lugs, make sure they are
being installed in the proper manner. Mechanical lugs use set screws for clamping onto the wire, where crimp lugs are
physically crimped to the cable with an approved tool from the compression lug manufacturer. Once the lugs are fixed to the
cable, install the lug onto the provided lug pads using required hardware. Torque the hardware based on the values in Table
7.1 on page43 .
Lashing
Cable lashing is recommended, but not required. The installer is allowed to do cable lashing if desired. The process of lashing
is laid out below.
Lashing should be performed by bundling the individual line cables and tap cables together using nominal 0.375 in. nylon rope
(or rope having a minimum tensile strength of 2000 lbs) at 6 in., and then after every 12 in. see Figure 4.33 below .
