Manufactured as a one-piece, seamless, high-conductivity copper unit, it is designed for secure, low-resistance terminations in medium-voltage electrical systems. The connector accepts 2\/0 AWG conductors, features a 0.439-inch inner diameter, and measures 3.13 inches in length. It is installed by licensed electricians working on medium-voltage distribution, underground feeder, and cable splicing applications where long-barrel geometry provides added contact area and pull-out resistance.\u003c\/p\u003e\n\u003cp\u003eThis connector is suited for medium-voltage copper conductor terminations in utility, industrial, and commercial electrical installations rated up to 35 kV. The long-barrel design accommodates applications where extended crimp length is required for mechanical and electrical integrity. It is typically used in cable jointing, switchgear connections, and underground distribution work where reliable, high-conductivity terminations are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated up to 35 kV for medium-voltage applications\u003c\/li\u003e\n  \u003cli\u003eOne-piece, seamless construction in high-conductivity copper\u003c\/li\u003e\n  \u003cli\u003eAccepts 2\/0 AWG copper conductors only\u003c\/li\u003e\n  \u003cli\u003eInner diameter of 0.439 inches for consistent conductor fit\u003c\/li\u003e\n  \u003cli\u003eLong-barrel design provides extended crimp zone for added pull-out resistance\u003c\/li\u003e\n  \u003cli\u003eLength of 3.13 inches for compatibility with standard medium-voltage tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with copper conductors only at 2\/0 AWG.

De-energize and verify the absence of voltage on all conductors before beginning termination work. Use only manufacturer-specified compression tooling and die sets appropriate for 2\/0 AWG long-barrel connectors to ensure a proper crimp. Do not use this connector on aluminum conductors.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 2\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: Up to 35 kV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.439 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-conductivity copper, one-piece seamless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000031380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343483797810,"sku":"7000031380","price":165.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535366.jpg?v=1782021990","url":"https:\/\/voomisupply.com\/products\/3m-7000031380-copper-long-barrel-connector-2-0-awg","provider":"Voomi Supply","version":"1.0","type":"link"}
