1. Construction of DLO Cable

1. **Conductor:**
   - DLO cables use finely stranded annealed tinned copper conductors for:
     - High conductivity.
     - Flexibility.
     - Corrosion resistance.
   - **Stranding:** The fine stranding enhances flexibility, making the cable suitable for tight bends and moving parts.

2. **Insulation:**
   - The conductor is insulated with a layer of **ethylene propylene rubber (EPR)**, which offers:
     - Excellent heat resistance.
     - Superior electrical properties.
     - Resistance to moisture and chemicals.

3. **Jacket:**
   - The outer jacket is made of **chlorinated polyethylene (CPE)**, providing:
     - Abrasion resistance.
     - UV and weather resistance.
     - Flame retardance.
   - The rugged jacket makes DLO cables ideal for outdoor and industrial environments.

4. **Voltage Rating:**
   - Typically rated for **2000V**, allowing use in high-power applications.

5. **Temperature Rating:**
   - Operates efficiently in temperatures ranging from **-40°C to 90°C** in wet conditions and up to **130°C** in dry conditions.

2. Applications of DLO Cable

1. **Diesel-Electric Locomotives:**
   - Originally designed to transmit high currents in locomotive engines, powering motors and auxiliary systems.

2. **Industrial Applications:**
   - Used in mining equipment, oil rigs, and shipyards due to its durability and flexibility.
   - Powers heavy-duty equipment and generators in harsh environments.

3. **Renewable Energy:**
   - Ideal for solar and wind power systems, where flexibility and UV resistance are critical.

4. **Battery Connections:**
   - Commonly used for battery interconnections in data centers, telecommunications, and backup power systems.

5. **Marine Applications:**
   - Suitable for marine environments due to its resistance to moisture, oil, and saltwater.
