DLO 2kV Flexible Diesel Locomotive Cable | TEBAOFLEX

TEBAOFLEX DLO Cable is a heavy-duty 2kV flexible power cable for diesel-electric locomotives, traction power systems, mining equipment, drilling rigs, marine power circuits and industrial mobile machinery. Built with a flexible copper conductor, rubber insulation and a tough protective jacket, it is suitable for demanding power connections where flexibility, abrasion resistance and oil resistance are required.

DLO Cable for Heavy-Duty Flexible Power Connections

DLO Cable, short for Diesel Locomotive Cable, is widely used in applications where a standard building wire or ordinary flexible cable cannot handle the working environment. TEBAOFLEX DLO Cable is designed for heavy-duty low-voltage power circuits that require flexibility, mechanical strength and long service life.

Although originally developed for diesel-electric locomotives, DLO cable is now used in many industrial power systems, including mining machinery, drilling equipment, shipyards, power conversion systems, motor leads, generators, battery banks and mobile equipment. It is a practical choice when the cable needs to carry high current while remaining flexible enough for installation in confined or equipment-mounted spaces.

Where DLO Cable Is Commonly Used

TEBAOFLEX DLO Cable can be considered for equipment power wiring in the following environments:

  • Diesel-electric locomotives and traction power circuits
  • Mining machines, shuttle cars and mobile industrial equipment
  • Oil and gas drilling rigs, generator sets and power skids
  • Marine equipment, shipyard power systems and dockside power connections
  • Motor leads, battery cables, rectifier wiring and inverter connections
  • Industrial plants where flexible 2kV power cable is required

Construction Overview

The DLO cable construction is built around three things: current-carrying capacity, flexibility and protection against harsh working conditions.

Why Engineers Choose DLO Cable

DLO cable is often selected when the installation needs more than basic electrical performance. In locomotive, mining, drilling and marine power systems, cables may face vibration, heat, oil exposure, tight routing and repeated handling during maintenance. A DLO construction helps solve these problems with a flexible conductor and a rugged jacket system.

For power circuits near motors, generators, batteries or rectifiers, DLO cable also offers easier routing than many rigid power cables. This makes installation and maintenance more manageable, especially inside crowded equipment compartments.

DLO Cable vs Welding Cable

DLO cable and welding cable can look similar because both are flexible single-conductor cables. However, they are not the same product. DLO cable is normally designed as a 2kV power cable with industrial ratings such as RHH / RHW-2 or RW90 depending on specification. Welding cable is mainly intended for welding leads and may not have the same voltage rating, jacket performance or approval package.

For fixed or equipment-mounted power wiring, engineers should confirm the required voltage, temperature rating, approvals, oil resistance, installation method and bending requirements before choosing between DLO cable and welding cable.

Frequently Asked Questions

What is DLO cable used for?

DLO cable is used for heavy-duty flexible power connections in diesel-electric locomotives, mining equipment, drilling rigs, marine systems, generators, motor leads, battery systems and industrial mobile machinery.

Is DLO cable the same as welding cable?

No. DLO cable and welding cable may look similar, but DLO cable is generally designed for 2kV industrial power circuits and may carry different approvals and jacket performance requirements. Welding cable is mainly used for welding equipment leads.

Can TEBAOFLEX supply customized DLO cable?

Yes. TEBAOFLEX can support different conductor sizes, jacket materials, cable markings, packing lengths and project-specific requirements. Share the current load, voltage, installation route and working environment for a more accurate recommendation.
