Jacketed versus Unjacketed Cable

     When looking at the different Raychem heat shrink kit options for medium voltage cable splicing, it quickly becomes apparent that there are a number of possible cable configurations in the market today...and that knowing which cable configuration you have is an absolute necessity when attempting to select the correct Raychem Medium Voltage Splice kit for your specific job.

     Over the next few days, I will be looking at some of these different 'options'.  These details are incredibly important.  When making a medium voltage splice (or any splice for that matter), the goal is recreate the structure of the manufactured cable in the splice area.  We want the cable configuration to be identical, whether looking at a manufacture portion or at the spliced section.

     Today I'm looking at what is probably the simplest one, jacketed cable and unjacketed cables.  This is most easily demonstrated through photos:
medium voltage cable splice.
This is a jacketed cable; notice multiple cables all surrounded by an outer PE jacket.

This is an unjacketed cable; notice that though the individual cables do have a PE jacket; they are not all housed within a single, outer PE jacket.
     Which ever type of cable you have, you want to make sure you purchase the correct corresponding Raychem splice kit in order to be sure you have all of the components you will need.
