Our take on the 2-2-2 Ramapo Triplex Aluminum Conductor Underground Direct Burial 600V URD Cable

This is a 600V aluminum triplex cable for single-phase underground secondary distribution, such as service drops from a transformer to a building. It has two 2 AWG phase conductors and a 2 AWG neutral, XLPE insulation, and is rated for direct burial or duct installation. Ampacity is 165 A direct-buried and 120 A in duct, with a 90°C maximum conductor temperature. It suits contractors and property owners running buried service feeders where aluminum triplex is accepted, and it competes with copper URD on weight and ease of handling rather than conductivity.

Pros
  • Rated for direct burial and duct use
  • XLPE insulation resists moisture and heat
  • 90°C maximum operating temperature
  • Triplex construction pulls and handles as one assembly
  • Aluminum conductors are lighter than equivalent copper
Cons
  • Aluminum needs proper connectors and anti-oxidant compound
  • Lower conductivity than copper of the same gauge
  • Ampacity drops to 120 A when run in duct
  • Not for overhead or higher-voltage primary work

What reviewers say

  • 5 / 5127 ratings

Buyers rate it highly and describe it as a solid, easy-to-handle triplex for buried service runs. Complaints are limited and tend to concern handling aluminum terminations correctly rather than the cable itself.

What people mention
  • HandlingPraisedOwners say the triplex assembly pulls and routes easily for a buried run.
  • Burial durabilityPraisedBuyers report the XLPE jacket and insulation hold up in wet direct-burial installations.
  • AmpacityPraisedReviewers say the current ratings match what they need for single-phase service drops.
  • Aluminum terminationsMixedSome note aluminum conductors demand correct connectors and anti-oxidant compound at each end.
  • Cold-weather stiffnessCriticisedA few find the cable stiff and harder to bend in cold conditions.

About the 2-2-2 Ramapo Triplex Aluminum Conductor Underground Direct Burial 600V URD Cable

This is a 2-2-2 Ramapo triplex URD cable with three aluminum conductors. It is rated 600V and made for single-phase secondary power distribution in underground electrical systems. It can be direct buried or installed in duct.

The triplex layout has two 2 AWG phase conductors and one 2 AWG neutral. The conductors are insulated with cross-linked black polyethylene (XLPE). The insulation is water tight and resists corrosive substances, oil, heat and flame. The cable is moisture-resistant and heat-resistant, and it works in wet and dry environments at up to 90°C.

The cable is used for single-phase service drops from transformers to buildings. Uses include service meters in residential and rural areas, small commercial buildings and municipal facilities, single-family homes and small multi-unit residences, street lighting, and residential solar and battery storage connections. It also supports temporary power for construction, events and backups.

Questions and answers

Can this cable be buried directly in the ground?
Yes. It is rated for direct burial as well as installation in duct, with 165 A allowable ampacity when buried and 120 A in duct.
What are the three conductors?
Two 2 AWG phase conductors and one 2 AWG neutral, arranged in a triplex configuration for single-phase service.
What voltage is it rated for?
600V, for single-phase secondary distribution in underground systems.
What temperature can it handle?
A maximum operating temperature of 90°C, and it is rated for wet and dry locations.
Is aluminum triplex as good as copper?
It carries less current than the same gauge in copper and needs proper aluminum-rated connectors, but it is lighter and accepted for most buried service drops.
Can it be used for overhead lines?
No. It is designed for underground direct burial or duct installation, not overhead service.
