Typically the two most common cables we consider for use in industrial and heavy duty applications are diesel locomotive cable (DLO) and welding cable. These two types of cables are often lumped together in the same category, but they are both designed with different uses and characteristics in mind.
So which cable type is the one you need? Read the differences between DLO cables and welding cables below for a clearer understanding and choice!
What is DLO cable?
Diesel Locomotive Cable (DLO) is a highly flexible cable designed for increased durability and performance. The cable features tinned copper stranded conductors, ethylene propylene rubber (EPR) insulation and a thermoset chlorinated polyethylene rubber (CPE) jacket. It is rated at 2000 volts, well-suited for heavy-duty, high-voltage applications. It also operates efficiently in both wet and dry environments. The maximum conductor temperature is 90°C in dry environments and 75°C in humid environments. DLO is typically UL approved. In addition, DLO cables from leading manufacturers such as ZW CABLE have a UL RHW-2 rating.
When to use DLO cable?
DLO cables have excellent resistance to oil, heat, fire and abrasion. Whether in industrial machinery, motor leads, drilling rigs, mining equipment, locomotives or power systems, DLO cables provide the strength and flexibility needed to withstand harsh conditions.
What is welding cable?
Welding cable is a highly portable and versatile cable designed for welding applications. It typically utilizes a copper conductor, which provides excellent electrical conductivity and flexibility. The cable is also encased in a rugged insulation, usually made of EPDM rubber, which features excellent durability and resistance to harsh conditions. Welding cables have a voltage capacity of 600 volts and can handle a variety of direct current (DC) and alternating current (AC) welding tasks. These cables stand up to abrasion, tearing, and cutting.
When to use welding cable?
Welding cables are very versatile and can be used in a wide range of applications other than welding. They are commonly used for starting automobiles, providing reliable battery grounding, and as a reliable power source in a variety of environments. They are also suitable for marine applications, where their durability and flexibility are particularly beneficial.
DLO vs Welding Cable: Which one is more suitable for the required?
Next, let’s dive into an important topic: “Which is better for your application, DLO or welding wire?” We’ll look at four key differences between diesel locomotive cable and welding wire and see if they’re interchangeable. Hopefully, you’ll find the answers you’re looking for in the following overview.
Difference #1: Sheath color and durability
Welding cables are usually sheathed in red or black, but other colors are available upon request. It should be noted that the orange color of the sheath indicates a particularly durable construction.
DLO cables are only available in black. The difference in sheath color matters for certain jobs where you need something tough and easy to see!
Difference #2: Conductor Material and Flexibility
Both Welding Cable and DLO Cable utilize stranded copper conductors. However, Welding Cable uses bare copper, which has more strands and is therefore more flexible, but difficult to terminate. In contrast, DLO Cable uses tinned copper conductors. The material is more resistant to corrosion and is more durable in harsh environmental conditions.
Difference #3: Ratings and Certifications
Welding cable and DLO cable have very different ratings and certifications; DLO cable has dual ratings, including UL RHH/RHW-2 (600V) and CSA R90 (1000V), while Welding Cable does not. Applications with higher voltages and specific regulatory approvals tend to require DLO wires.
Difference #4: Application Suitability
Depending on the particular needs of your application, you may choose between DLO and welding cables. Because of its single jacket and finely stranded conductors, welding cable is more flexible and appropriate for confined locations. In contrast, DLO cables are more frequently used in heavy-duty and industrial applications and feature tinned conductors, insulation, and jacketing.
Can DLO and Welding Cables Be Used Interchangeably?
In high current applications, DLO cables can replace welding cables due to their excellent load performance and durable insulation. However, DLO wires should not be used in situations where additional flexibility is required, as welding cables offer greater flexibility in such situations.
On the contrary, welding cables are not a suitable replacement for DLO cables in most industrial applications. It mainly supplies power to the secondary circuit of the welding machine. Because of their lower voltage ratings, their use in industry is limited. Under high voltage and severe abrasion conditions, DLO cables are more versatile and reliable.
Conclusion
Welding cables and DLO cables have both similarities and differences in industrial electrical cable applications. Therefore, when choosing between these two types of cables, it is important to accurately consider the needs of your application.
