Revision F November 2021 

 
 

To reduce the amount of the cable damage during cutting and limit fraying, tape must be wrapped 
around the cable and the cut made through the tape. 

Some agencies have also cut through 

the  turnbuckle  itself.

 

This  may  help  to  reduce  the  maintenance/repair  effort.  When  cutting 

through a turnbuckle, ensure that all posts, both upstream and downstream for a distance of 50’-
0” [15 m], are removed in order to prevent turnbuckle or fitting interference. 

If time permits, the tension can be released by pushing over one or more of the CRP(s) with a 
piece of equipment. 

Removing Entangled Cable from a Vehicle 

When the cable is entangled with a vehicle that must be towed away, remove the entangled cable 
by lifting one or more of the cables up over the vehicle. During this operation, if any of the line 
posts entangled with the cable start to lift up out of the sleeves, the lifting must be stopped and 
the posts removed from the cable. Once the posts are removed, the cable can be lifted up over 
the vehicle. 
In addition, if the entangled vehicle is located near the CCT end, it is possible to reduce tension 
by loosening the two large nuts on the terminal cable end.  The nuts can be backed off to the end 
of the fitting.  

DO NOT COMPLETELY REMOVE EITHER OF THE NUTS!

 

Repairing a Cut or Damaged Cable 

Following are various methods to repair cables that have been cut or damaged: 

 

Method 1 – Splicing the Cable  

 

Splicing the cable may be necessary if a cable is cut or damaged during an impact.  The length 
of the cable must be 50’-0” [15 m] or longer to make the splice. 

1.  Re-cut the ends of the cable to ensure the ends are clean and smooth. 
2.  Refer to the 

“Cable Splices

” Section when making a cable splice connection. 

3.  If  an  accurate  length  of  cable  is  used  for  the  splice  section,  two  cable  splice 

connectors will be required to connect the cables together. 

4.  Connect one end of the splice cable to one end of the cut cable with a connector. 
5.  Apply another connector to the other end of the splice cable and the end of the 

cut cable. 

6.  Assemble the cable splice connector using a backhoe or other mechanical means. 
7.  Check the tension on the cable with the tension meter and adjust the turnbuckles 

to bring the cable to the correct tension based on the infrared thermometer cable 
temperature  reading  and  the  values  on  the  CASS

®

  S3  Temperature/Tension 

Chart. 

Note: 

If the cable splice has been cut accurately, the tension may be obtained by turning the 

turnbuckles at each side of the cut. 
If the tension cannot be obtained at the turnbuckles at each side of the splice, it may be necessary 
to follow the procedures in the 

“Tension and Tension Meter

” Section.  Some assemblies may 

have field splices at all locations. If this is the case, the measuring, cutting, and re-connecting can 
be done at any location. 
 

Method 2 – 5’-0” [1.5 m] Section 

A second method to reconnect the cables is to use a 5’-0” [1.5 m] Cable Field Repair Section 
(PN-5840G) of cable with a factory applied fitting on each end. This method will also require two 
turnbuckles and a left-hand and right-hand threaded fitting to complete the connection. 

1.  Remove approximately 9’-8” [2.9 m] of cable from the cut cable.
