HW291

Application:

Designed and constructed to be a flexible alternative to Type MC cable where crush and impact protection in arctic conditions is required.

Features

  • Complies with the requirements for TC-ER-HL* per UL 2225
  • Gas & vapor tight – impervious to water and air
  • Smaller bend radius (up to 40% smaller) than Type MC
  • Reduced tray fill (up to 35% less) compared to Type MC
  • Considerably more flexible than Type MC
  • Brittle point as per ASTM D 746-07 exceeds -65°C for Jacket and -75°C for Insulation
  • Exceeds CSA cold bend / cold impact (-40°C / -35°C)

Conductor

  • Soft annealed flexible stranded tinned copper per IEEE 1580 Table 11.

Insulation

  • Gexol cross-linked flame retardant polyolefin, meets requirements for Type P of IEEE 1580 and Type X110 of UL 1309/CSA 245. 600V/IEC 1000V.

Shielding

  • Each pair/triad is twisted with a bare tinned drain wire. Each pair/triad is shielded with polyester-backed aluminum foil tape to afford 100% coverage. Pair to pair or triad to triad, isolation – plus overall shielding – is provided.

Grounding Conductor

  • Soft annealed, flexible stranded, uninsulated, tinned copper sized in accordance with UL 1277.

Jacket

  • A black, flame retardant, oil, abrasion, chemical and sunlight resistant thermoset compound meeting UL 1309/CSA 245 and IEEE 1580.

Ratings and Approvals

  • 90°C temperature rating
  • UL Listed as Marine Shipboard Cable (E111461)
  • UL Listed as Type TC-ER
  • UL Listed as Type TC-ER-HL*
  • American Bureau of Shipping (ABS) (99-BT5905-X)
  • Flame Retardant – IEEE 1202
  • Suitable for use in Class I, Div 2 & Zone 2 environments
  • Suitable for use in Class I, Div 1 & Zone 1 environments*
  • *Cables up to 1” in OD

Notes

Ampacities are based on Table 310.16 of the National Electrical Code (NEC) for conductors rate 90°C, in a multi-conductor cable, at an ambient temperature of 30°C. The 75°C column is provided for additional information. The ampacities shown apply to open runs of cable, installation in any approved raceway. Derating for more than three current carrying conductors within the cable is in accordance with NEC Table 310.15 (B) (2) (a). Ampacities shown also apply to cables installed in cable tray in accordance with NEC Section 392.11.
