Product Overview
DLO Cable (Diesel Locomotive Cable) is a heavy-duty, single-conductor portable power cable engineered for extreme flexibility, durability, and performance in demanding industrial environments. Rated for 2000V and 90°C operation (wet or dry), it features a dual-layer CPE/EPR insulation system, tinned copper conductors, and compliance with UL 44, UL 1685, MSHA, and RoHS standards. Ideal for locomotives, renewable energy systems, marine applications, and heavy machinery, this cable excels in high-flex, high-abrasion, and hazardous conditions.
Key Features
-
Ultra-Flexible Design: Rope-lay-stranded tinned copper conductors (ASTM B-33/B-172) for superior bend radius and flex life.
-
Dual-Layer Insulation: Flame-retardant CPE outer jacket + EPR inner layer for oil, UV, and abrasion resistance.
-
Hazardous Environment Rated: MSHA P-184 compliant for mining and FT4/IEEE 1202 flame-resistant.
-
Multi-Certification: UL-listed as RHH/RHW-2, sunlight-resistant, and marine shipboard (4/0+).
-
Eco-Compliance: RoHS-certified, meets 40CFR261 hazardous waste regulations.

Installation Guidelines
-
Bending Radius: Minimum 8x cable diameter to maintain insulation integrity.
-
Temperature Handling: Avoid installation below -40°C without pre-conditioning.
-
Securing: Use abrasion-resistant clamps in high-movement applications.
-
Termination: Use tinned lugs for corrosion resistance in marine environments.
-
Prohibited Uses: Not for permanent fixed installations or continuous immersion.
Why Choose DLO Cable?
-
Unmatched Flexibility: Rope-lay stranding withstands repeated bending and vibration.
-
Durability: Dual-layer CPE/EPR insulation resuts oil, UV, and mechanical wear.
-
Safety Compliance: UL, MSHA, and FT4 certifications ensure reliability in critical environments.
-
Space Efficiency: Compact design reduces bulk in tight installations.
-
Cost Savings: Long service life reduces downtime and replacement costs.
