    Compression Splices

    Most of the time spec calls for mechanical splices but have to use compression in this case. Do compression take longer than mechanical and is so why? Any particular compression splice you guys favor? Thanks.

    We use Burndy with battery operated crimpers. Yes they take a little longer because you need to crimp both sides of the splice (anywhere from 2-5 per side) and then install a cold shrink. A Polaris type splice you just strip, insert, and torque. Done.

    Thanks. Why cold shrink and not heat shrink? Only familiar with heat shrink.

    Not sure what you're crimping but I use these for electric services :

    If you have $$ to burn like Infinity does you can use a $600 - $700 Greenlee battery operated power crimper or you can get one of these for about $150:

    Cold shrinks require no tools and are somewhat more foolproof. In over 30 years I have never used heat shrinks on compression splices.

    At Mrluckys labor rate two journeymen using that battery crimper for two or three days will pay for itself over a manual crimper.

    If you're planning on making a lot of crimps maybe you're right. While I'd love to have one of those power crimpers the job would have to justify the cost.

    I agree completely, for a few crimps on an occasional service the manual ones are fine but for any type of large work, big riser boxes or services, etc. the battery ones are the way to go. Would hate to do this by hand.

    I agree. Nice work BTW !!! I've already had carpal tunnel surgery and my fingers occasionally lock up just from squeezing pliers for so many years.

    yeah, it will.

    the cold shrinks are faster by far
    than heat shrinks, but far more expensive.

    i've used the panduit heavy walled heat shrinks
    a lot. it's UL listed for direct burial @600 volts.
    the panduit stuff is in 3' and 4' lengths. you cut
    to fit.

    it's 10%~20% of the cost of 3m cold shrinks.

    No tools? How is it done?
