2.3.3
Protective Coverings and Cable Jackets
Protective coverings and cable jackets in any single length of cable shall
be continuous and of the same material. The protective coverings shall be
free from holes, splits, blisters, and other imperfections. The covering
shall be flame retardant, moisture resistant, nontoxic, and electrically
nonconductive. All interior cables' insulation and jacketing material
shall not contain any poly vinyl chloride (PVC) compounds.
2.3.4
Underground Cable
Where cable is installed in buried conduit, the cable shall contain an
additional moisture barrier in the form of a flooding compound interspersed
between the outer polyethylene jacket and the sheath. The flooding
compound shall be electrically non-conductive, non-corrosive, and as
recommended by the cable manufacturer.
2.3.5
Direct Burial Cable
**************************************************************************
NOTE: The designer will use this Paragraph if a
rodent problem (such as gophers and prairie dogs)
has been verified at the installation site or if the
cable outer jacket might be damaged by adjacent
sharp rocks or debris when the cable is going to be
installed by direct burial.
**************************************************************************
Direct burial cable shall be protected with a steel armor (spiral wrap or
corrugated). The steel armor shall be plastic coated or chrome plated or
have a second polyethylene jacket protecting the steel from corrosion. The
steel armor shall be applied longitudinally and have an overlap of at least
5 mm 3/16 inch. An inner jacket for armored cable is required. Flooding
compound shall be applied to armored cable between the inner jacket and
sheath. The flooding compound shall be electrically non-conductive,
non-corrosive, and as recommended by the cable manufacturer.
2.3.6
Drop Cable
Drop cable used to connect distribution cable taps to terminal equipment
shall be 100 percent shielded with aluminum foil or aluminized plastic
covered by at least 40 percent aluminum braid and a polyvinyl chloride
jacket. The foil shield shall be bonded to the cable dielectric.
Shielding effectiveness shall be at least 80 dB at all frequencies from 50
