Type P power
IEEE 1580 offshore power cable, XLPO, unarmoured, bronze braid armoured (B) or armoured and sheathed (BS), 0.6/1 kV
Type P is a flexible offshore and marine cable for 0.6/1 kV to IEEE 1580, listed to UL 1309 as Type X110. Flexible stranded tinned copper, XLPO insulation and a thermoset sheath. Unarmoured, with a bronze braid (B) or with braid and outer sheath (BS), in 2 to 5 cores from 18 AWG (0.96 mm²) to 777 kcmil (393.87 mm²). Supplied to order; the lead time is stated in the quote.
Type P is a flexible offshore and marine cable to IEEE 1580, listed to UL 1309 / CSA 245 as Type X110, rated 0.6/1 kV with a conductor temperature of up to +110 °C. The conductors are soft annealed, flexible stranded tinned copper to IEEE 1580 Table 11, insulated with cross-linked, flame-retardant polyolefin (XLPO). Over the cores lies a black, arctic-grade thermoset sheath that resists oil, abrasion, chemicals and sunlight. The cable comes in three versions: unarmoured, with a bronze basket-weave armour (B), and with that armour plus a thermoset outer sheath that also resists drilling mud (BS). The high strand count makes Type P flexible and resistant to vibration, which matters on drilling and production facilities. Only the BS version is suitable for Class I Division 1 and Zone 1. This page covers the two- to five-core power cable; for multi-core control cable, see Type P control.

Applications
- Power distribution and supply on drilling rigs, drill ships and production platforms.
- Installations designed to IEEE 45, or where the specification calls for Type P.
- Cable routes with vibration or tight bends, where a flexible cable makes the job easier.
What to look out for
- Only the BS version is suitable for Class I Division 1 and Zone 1. NEC Article 337 requires fittings listed for the location there. State the version in your enquiry.
- AWG sizes do not coincide with the IEC mm² series: in this cable 4/0 AWG is 108.91 mm², between 95 and 120 mm². Calculate current and voltage drop with the cross-section from the table.
- The datasheet does not state that the sheath is halogen-free. If the specification calls for halogen-free to IEC 60754, choose a NEK 606 type such as RFOU.
- Type P falls outside EN 50575 and so has no CPR class. Where the cable is exposed to indoor air in a building, the Bbl does require a class; choose another cable there.

Nominal manufacturer values, with a manufacturing tolerance of ±5%. The equivalent c.s.a. per size is the manufacturer’s value for its stranded conductor, not the nominal AWG cross-section (18 AWG: 19 strands of 0.0100 inch, 0.96 mm²; nominal 0.82 mm²). In a few sizes the weights on the sheet do not rise consistently with the size or the number of cores, especially in 16 AWG. We reproduce the values as published.

Current ratings from the datasheet. At +110 °C and +100 °C to IEEE Std 45, at 45 °C ambient with a single layer of cables per hanger; for two layers multiply by 0.8. At +95 °C to Table 4/3C.10 of the 1997 ABS MODU rules, also at 45 °C. The classification society decides which column applies: ABS allows +100 °C; DNV, Lloyd’s Register and Transport Canada allow +95 °C. The four-core ratings assume that one conductor carries no normal current, such as an earthed neutral or an earth conductor. In free air the IEEE Std 45 values may be divided by 0.85. For 3 × 535 kcmil at +110 °C we state the lower four-core value (463 A); at every other size the three-core and four-core ratings are equal.

Both are 0.6/1 kV offshore cables with tinned copper. Type P follows IEEE 1580 and UL 1309, with XLPO insulation and, in the B and BS versions, a bronze braid; sizes are in AWG and kcmil. RFOU follows NEK TS 606, with EPR insulation, a tinned copper braid and a halogen-free sheath; sizes are in mm². If the specification calls for Type P or IEEE 1580, choose Type P. If it calls for NEK 606 or halogen-free, choose RFOU.

Standard and versions are the same. Type P power is a power cable with two to five cores, also in large cross-sections, for supplying motors and distribution boards. Type P control has many cores of a small cross-section, for control and signalling; above 37 cores the cores are black with numbers. Choose power for supply and control for control circuits.
