1111 MCM Diesel Locomotive Cable, 2000V

1111 MCM Diesel Locomotive Cable (DLO) is an ultra-heavy-duty, single-conductor portable power cable designed for massive industrial power distribution networks and maximum high-stress electrical setups. Engineered to safely manage a continuous electrical pressure of 2000 Volts, this high-capacity power line is built to survive heavy vibration, aggressive mechanical handling, and unforgiving field conditions.

While originally developed to feed high-voltage electrical energy from traction generators to the drive motors of heavy diesel-electric locomotives, its raw strength and exceptional flexibility make it a top choice for stationary and mobile applications. It serves as an ultra-flexible alternative to standard, stiff commercial building wire (such as THHN or XHHW-2) in complex commercial installations requiring tight bends or continuous dynamic motion.

ELECTRICAL AMPACITY & PERFORMANCE DATA

Thanks to its dense network of fine-drawn strands and a thick dual-layer insulation assembly, 1111 MCM DLO exhibits outstanding thermal dissipation properties and ultra-high-current handling limits:

• Maximum Current Capacity (30 degrees C Ambient Air): 1225 AMPS This premium capacity rating is evaluated based on a continuous 90 degrees C conductor temperature operating in an open-air cable tray environment.

• National Electrical Code Adjustments: When packing multiple single-conductor 1111 MCM DLO lines inside a closed structural conduit, wire trough, or enclosed raceway, electricians must apply NEC Article 310 derating adjustments based on ambient room temperatures and total enclosed conductor counts.

Key Features

• Extreme-Flexibility Class I Tinned Copper Conductor: Composed of 2755 individual strands of fully annealed tinned copper. This ultra-fine layout allows a massive 1,111,000 circular mil (MCM) conductor to bend smoothly around architectural structures without kinking, while the outer tin layer neutralizes copper oxidation and simplifies lug terminations.

• Premium EPR (Ethylene Propylene Rubber) Insulation: Shielded by a thick layer of high-dielectric EPR insulation. This thermoset material resists softening, melting, or cracking under extreme temperature fluctuations and protects the core against internal voltage tracking failures under 2000V loads.

• Heavy-Duty CPE (Chlorinated Polyethylene) Outer Jacket: Wrapped in an industrial-grade, abrasion-resistant black CPE jacket. It stands up to grease, fuel oils, petrochemical solvents, ozone, severe structural impacts, and nonstop open-air sunlight exposure.

• Multi-Certified Safety Standard Ratings: Dual-listed as Type RHH/RHW-2 under UL 44, making it fully code-compliant for continuous permanent installation at 90 degrees C in both wet and dry architectural applications.

Common Applications

• Diesel-Electric Locomotive Networks: Distributing high-amp energy paths between central engine generator blocks, dynamic braking grids, and heavy-duty wheel traction motors.

• Oil and Gas Drilling Rigs: Powering massive mud pumps, top drives, drawworks equipment, and offshore marine drilling platforms.

• Data Centers & Bulk Battery Storage Hubs: Interconnecting massive Uninterruptible Power Supply (UPS) systems, utility-scale battery storage arrays, and high-voltage emergency backup setups.

• Industrial Motor & Generator Leads: Acting as a flexible, high-current feeder line on mining shovels, heavy manufacturing motors, and large mobile generator sets.

• Shipboard & Marine Power Distribution: Supplying heavy-duty flexible power trunks across shipyards, commercial transport vessels, and marine docks.

Cable Layer Architecture (From Core to Jacket)

1. Central Conductor: 1111 MCM rope-lay, bunch-stranded tinned copper core (2755/24 layout configuration).

2. Separator Layer: Clear polyester or paper binding tape to prevent the fine copper strands from sticking to the primary insulation layer during high-heat stripping and termination work.

3. Primary Insulation: Premium-grade Ethylene Propylene Rubber (EPR).

4. Outer Protective Armor: Rugged, thermoset, weather-proof Black Chlorinated Polyethylene (CPE) jacket.

Technical Note Regarding Lugs: Because 1111 MCM DLO cable is engineered with extra-fine Class I stranding, standard mechanical compression lugs or standard commercial building wire barrels must never be used. Trying to crush fine stranding into a standard building wire lug will tear the individual copper fibers and create a serious fire hazard due to loose electrical connections. Installers must exclusively use specialty chamfered compression lugs explicitly stamped and rated for "Flexible Strand, Class I, or DLO Cable" and secure them using calibrated crimping dies.
