4c Central aluminum phase conductors shall be one on the following:
(3) - This part should be changed to 4d which would require the
conductor to be filled whether copper or aluminum.
The requirement to fill the conductor interstices so as not to allow moisture to
migrate through the conductor should be for both aluminum and copper conductor
and not just for aluminum conductor. Filling the strands of a conductor is done to
pick moisture out of the conductor and whereby limiting the moisture that can
migrate into the insulation.
4c (4) ? Remove requirement for indent printing on a solid conductor.
Requiring indent print on solid conductors does seem consistent with keeping the
interface of the conductor and extruded components smooth. Using indent on a
solid conductor will cause the surface of the conductor have some metal
displacement and create irregularities on the conductor surface. Indent printing
on the center strand of a stranded conductor is being used today on cables and
this type of identification should be limited to stranded conductor and not used on
solid conductor use for medium voltage cables.
7c ? The requirement of stripping tension for TR-XLPE cable should be changed to
the industry standard of a maximum of 24 lb.
Limiting the maximum stripping tension to 18 lb will cause quality
cable to be rejected based on a difference of 6 lb. The industry standards require
that the cables be able to be stripped at temperatures between -10C and 40C with
out tearing based on a defined test procedure regardless of the actual stripping
tension.
10. Dimensional Tolerances
Remove this section since diameter tables referred to in this
specification do not have nominal diameters. The ICEA diameter tables now state
minimum and maximum diameters, therefore this statement in 10. is no longer
needed or relevant.
11 b Partial Discharge Tests:
Changed wording to:
Discharge Tests: Manufacturers shall demonstrate that their cable meets either
the partial discharge test for Discharge Free cable design or the Discharge
Resistance test for Discharge Resistant cable designs as required per ICEA S-94-
649 and as described in b(1) or b(2) of this bulletin.
11 c (1) Jacket tests
This requirement should be omitted.
Since polyethylene?s (low, medium and high density) have excellent cold
temperature properties, there is no need to do cold bend test. ICEA standards do
not require a cold bend test for these jacket materials for the reason stated
above. Jacket materials such as Polyvinyl Chloride (PVC) and Chlorinated
Polyethylene (CPE) do require a cold bend test but are not allowed to be used in
this specification.
