Raceway ampacities are based on NEC (NFPA 70) Table 310.16 for not more than three current-carrying conductors in raceway, cable or earth at 30 °C ambient.
Free-air ampacities are based on single-conductor installation in free air at 30 °C ambient and 90 °C conductor temperature per NEC Table 310.17 / ICEA P-54-440.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why is DLO cable dual-rated as UL Type RHH/RHW-2 as well as locomotive cable?

Originally developed under AAR RP-585 for diesel-electric locomotives, modern DLO 2 kV is dual-listed to UL 44 Type RHH/RHW-2 (600 V / 2,000 V, 90 °C wet or dry) and CSA RW90. This allows the same extra-flexible cable to be installed in NEC-compliant industrial raceways, cable trays (1/0 AWG and larger), battery energy storage racks and VFD cabinets without requiring separate building wire transitions.

Can standard compression lugs for Class B building wire be used on DLO 2 kV conductors?

No. DLO uses extra-flexible Class I / Class K rope-lay stranding made from fine 24 AWG (0.51 mm) tinned copper wires, resulting in a slightly larger compacted conductor diameter and much softer bundle than 7- or 19-strand Class B copper. Always use flared-barrel compression lugs and dies specifically UL-listed for flex / DLO stranding to prevent strand cutting or high-resistance hot spots.

Which sizes of DLO 2 kV are permitted in open industrial cable trays?

Under NEC Article 392, single-conductor cables installed in open ladder or ventilated trough cable trays must be 1/0 AWG (53.5 mm²) or larger and carry the surface marking 'For CT Use'. TEBAOFLEX DLO sizes from 1/0 AWG through 1111.1 kcmil pass the IEEE 1202 / FT4 (70,000 BTU/hr) vertical tray flame test and carry the CT rating.

How does the two-layer EPR / XL-CPE construction perform in diesel oil and sub-zero cold?

The inner thermoset EPR layer provides high dielectric strength, corona resistance and a +90 °C continuous (+130 °C overload, +250 °C short-circuit) thermal profile, while the outer cross-linked chlorinated polyethylene (XL-CPE) sheath resists hot diesel fuel, hydraulic oils (UL Oil Resistant I & II), abrasion and UV sunlight while remaining flexible down to −40 °C.
