DLO Cable Sizes, Ratings and Selection
TEBAOFLEX manufactures 2 kV DLO cable — sold interchangeably as DLO wire or diesel locomotive cable — from 14 AWG to 1111.1 kcmil for locomotive, mining, motor, generator, battery, UPS and industrial power applications.
Choose the conductor size from the actual load, installation method, ambient temperature, grouping, terminal rating and governing electrical rules. Fine-stranded DLO conductors also require compatible lugs or ferrules and the correct crimp tooling. DLO is not automatically interchangeable with welding cable, and it is not a continuous-reeling cable simply because it is flexible.
- Suitable for: flexible 2 kV single-conductor power links.
- Specify by: AWG/kcmil size, route, current basis, temperature and required marking.
- Confirm: termination system, wet/dry duty, tray or conduit requirements and documentation.
- Choose another cable when: the circuit needs multiple cores, shielding, armour or continuous drum reeling.

DLO Cable Manufacturer, Pricing Factors and Supply Terms
TEBAOFLEX (Jiangsu Tebaoflex Special Cable Co., Ltd.) manufactures DLO cable to order at its plant in Taicang, Suzhou, Jiangsu, China. The company was founded in 2014, holds an ISO 9001:2015 certificate for the production of power cables (certificate 244-24-QI-17425-R0-Q) and has an annual capacity of about 150,000 km of cable. Flexible cables from this plant have been exported to more than 20 countries across Africa, South America, Southeast Asia, Australia, Russia, Germany and the UAE. Every DLO enquiry is reviewed by the engineering team before a quotation is issued.
DLO cable price depends on conductor size, copper content, ordered length, certification/marking requirements, packing and destination. For a current quotation, send the required AWG/kcmil size, total length, quantity and destination country.
Project reference: 444.4 kcmil DLO cable was supplied with matching cast copper DLO cable lugs marked 1100/24 for locomotive traction motor leads. The lugs are available as a regular item with this cable.
Supply and ordering
- Minimum order quantity: 50 m, for standard and custom constructions.
- Cut lengths: supplied cut to the ordered length; state the required length per drum in the RFQ.
- Typical lead time: 7–45 working days depending on size, construction and order details; the written quotation governs.
- Jacket colour: black as standard; other colours on request.
- Packing and marking: drum size, cable marking and the document package are confirmed at quotation.
DLO Cable Construction
The DLO cable build combines a fine-stranded power conductor with separate thermoset insulation and jacket layers. This differs from a single-layer welding lead and gives the buyer a defined 2 kV power-cable construction with size-dependent building-wiring and tray-use markings.| Layer | Verified construction | Buyer value |
|---|---|---|
| Conductor | Flexible rope-lay Class I tinned annealed copper, manufactured using bunch-stranded components | Supports routing through compact locomotive, equipment and power-distribution layouts; tin coating assists corrosion control at the conductor surface. |
| Separator / binder | Non-hygroscopic separator tape over the conductor | Helps prevent the thermoset insulation from penetrating the fine strands and supports clean preparation for termination. |
| Insulation | Black thermoset ethylene propylene diene monomer (EPR) | Provides the primary 2 kV dielectric layer and supports 90°C operation in wet or dry locations. |
| Outer jacket | Thermoset chlorinated polyethylene (XL-CPE), black as standard; other colours by order | Provides resistance to oil, sunlight, abrasion, heat, flame exposure and routine industrial handling. |
| Identification | Surface, indent or sequential marking options showing the ordered model, size, voltage and applicable approval marks | Allows receiving inspectors and installers to verify that the delivered cable matches the approved submittal. |
Termination of the Fine-Stranded Conductor
Use compression lugs, ferrules or connectors specifically qualified for fine-stranded Class I/DLO conductors. A lug intended only for conventional building-wire stranding may not capture every strand or maintain the intended contact pressure. Strip the insulation without nicking or splaying the conductor, follow the connector manufacturer's die and crimp sequence, and verify the completed termination against the project procedure.TEBAOFLEX supplies matching cast copper DLO cable lugs with the cable; the 1100/24 lug case for 444.4 kcmil DLO shows the lug sizes and dimensions.
DLO Cable Applications
DLO cable is selected where a single flexible power conductor must carry substantial current through compact equipment, exposed industrial routes or connections that need easier handling than conventional rigidly stranded power cable.- Diesel-electric locomotives, railway vehicles and transit-car power wiring.
- Mining, drilling, earth-moving and other electrically driven industrial equipment.
- Flexible motor leads, generator leads, transformer connections and switchgear links.
- UPS systems, battery banks, energy-storage equipment and standby-power connections.
- Wind-turbine generator power leads and industrial plant power connections.
- Wet or dry conduit, duct and trough routes when the ordered marking and local electrical rules permit.
- Cable-tray installations for 1/0 AWG and larger when the delivered cable carries the required CT-use and flame-test marking.
For higher-voltage wind-turbine circuits beyond this DLO cable’s 2 kV class, compare (N)TSCGEHXOEU 12/20–20/35 kV twist cable, (N)TSCGEHXOEU 36/60–69 kV high-voltage cable and (N)TMCHXOEU 12/20 kV single-core cable. Select by voltage, core arrangement and movement duty; these are distinct constructions.
Selection Boundaries
DLO describes a flexible single-conductor cable family; it does not by itself approve every installation. Confirm the local electrical code, authority having jurisdiction, conductor ampacity, terminal temperature rating, grouping and ambient-temperature derating, and the exact sheath marking before installation. Use a purpose-designed reeling cable for continuous drum duty and a multi-core, screened or armoured cable where the circuit or mechanical risk requires those features.DLO Cable Is Not Automatically Interchangeable with Welding Cable
Welding cable is normally intended for welder secondary circuits. Substitution in either direction must be based on the voltage rating, insulation system, approved use, flame performance, environmental exposure and termination method—not conductor flexibility alone.DLO Cable FAQ
For what DLO cable is, what the acronym stands for and how its markings differ, read the explainer on what DLO cable is; the questions below cover selection and ordering from TEBAOFLEX.
What is the difference between DLO cable and Type W cable?
Both are 2 kV, 90°C flexible cables with tinned copper, EPR insulation and CPE jackets. DLO is a single-conductor cable with a thinner two-layer wall made for equipment leads and for conduit or tray routes where its marking permits. Type W is a portable power cable, single- or multi-conductor, with an extra-heavy-duty jacket for dragging and portable-equipment duty in mining. Choose by conductor count, mechanical duty and the marking the installation requires.
Can you bury DLO cable?
Not without a raceway. DLO is not a direct-burial cable type on its own; underground runs are normally made in conduit or duct where the wet-location marking and the local electrical rules permit. When the route requires burial without a raceway, specify a cable designed and marked for direct burial instead.
What are the minimum order quantity and lead time for DLO cable?
The minimum order is 50 m for standard and custom constructions. Lead time is typically 7–45 working days depending on conductor size, jacket colour, marking and quantity, and is confirmed in the written quotation. Cut lengths, reel or coil packing and custom print legends are available.
What should I send for a DLO cable quotation?
Send the size or sizes in AWG or kcmil, the length and quantity, the marking required (RHH/RHW-2, RW90, CT-use), jacket colour and print legend, packing (reels, coils, cut lengths), destination country or port, documentation needs such as test reports or inspection, and whether matching lugs are required. The engineering team returns a data sheet and quotation.
