What type of wire is Dlo?
Diesel Locomotive Cable which is commonly known as DLO Cable is a flexible (tinned copper Class I, 24 AWG strands) rubber insulated (EPR—Ethylene propylene rubber) and rubber jacketed (CPE-chlorinated polyethylene) 2000 volt UL rated cable originally developed for use in the wiring of Diesel Locomotives.
What is Dlo electrical?
Diesel locomotive cable, also known as DLO cable, is a flexible portable power cable designed for use in diesel-electric locomotive engines. Our DLO cable features a stranded tinned copper conductor, EPR insulation, and a CPE jacket.
What is 250 MCM wire?
For example, one common wire size used in the NEC has a cross-section of 250,000 circular mils, written as 250 kcmil or 250 MCM, which is the first size larger than 0000 AWG used within the NEC. 1000 circular mil equals 0.5067 mm2, so for many purposes, a ratio of 2 MCM ≈ 1 mm2 can be used with negligible (1.3%) error.

What is the maximum ampacity of a wire?
Maximum Ampacity: 25 Amps Note: These values are based on allowable ampacities of insulated conductors rated up to and including 2000 volts, not more than three current-carrying conductors in a raceway, cable, or Earth, single-insulated conductor in free air, and an ambient air temperature of 30°C (86°F).
What is the ampacity of diesal locomotive cable?
Diesal Locomotive Cable “Ampacity” is defined as the maximum current, in amperes, that a DLO Cable conductor can carry continuously under the conditions of use without exceeding its 90C temperature rating. This is also described as dlo cable current rating, its current-carrying capacity.
What is the ampacity of a DLO wire?
The ampacity of a DLO Wire conductor depends on its ability to dissipate heat without damage to the conductor or its EPDM Rubber insulation. DLO cable amps is a function of the insulation temperature rating, the electrical resistance of the conductor material, the ambient temperature, and the ability of the insulated conductor to dissipate heat.
