I. Scope
This specification covers single conductor wire and cable rated at 600/1000 volts or 2000/1000 volts, AC or DC, insulated with
General Cable’s Polyrad XT-125 Type P Marine insulation, a thermosetting irradiation cross-linked polyolefin which is flame
retardant, moisture- and oil-resistant, and mechanically tough. Armor of aluminum or bronze and an arctic-grade overall sheath in
accordance with IEEE Standard 45/ IEEE Standard 1580-2010 is available at the option of the purchaser.
IEEE 1580 Type P cables should be designed, engineered and produced by cable manufacturers that have manufactured these
specific cables for a minimum of 15 years. These manufacturers should be actively involved in the standards organizations that
support the continued development, safety and quality of IEEE 1580 Type P cables.

tube. A copper coated glass mirror shall be suspended 6 inches over the sample by a thin copper wire. The lower two
inches of the test tube shall be heated to 175°C for 16 hours.
Requirement: Remove less than 5% of the copper film.
b) Acid Gas Detection: A 1.0 mg sample shall be heated to combustion in a closed quartz tube. The resulting gases
are drawn through a detector tube (MSA #91636) using a special air sampling pump manufactured by Mine Safety
Apparatus Company. The amount of acid gas is determined by measuring the length of the color change in the
detector tube.
Requirement: 220 PPM/MG typical.
