Manufactured from one-piece, seamless, high-conductivity copper, this lug delivers low-resistance, reliable terminations in demanding power distribution applications. It features a 1\/2 inch stud size, a 0.836 inch inner diameter, and an overall length of 4.500 inches. The seamless construction eliminates weak points associated with seamed or brazed barrel lugs, making it a dependable choice for licensed electricians and utility contractors working on medium-voltage cable terminations.\u003c\/p\u003e\n\u003cp\u003eThis lug is suited for medium-voltage power distribution installations, including utility, industrial, and commercial applications where copper conductors at 500 kcmil are terminated to switchgear, transformers, or bus connections. It is rated for use on copper conductors only and is appropriate for systems operating up to 35 kV. Licensed electricians and power system technicians typically install this lug in applications requiring secure, high-conductivity terminations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece seamless high-conductivity copper construction for reliable, low-resistance terminations\u003c\/li\u003e\n  \u003cli\u003eRated for medium-voltage systems up to 35 kV\u003c\/li\u003e\n  \u003cli\u003eCompatible with 500 kcmil copper conductors\u003c\/li\u003e\n  \u003cli\u003e0.836 inch inner diameter barrel for proper conductor seating\u003c\/li\u003e\n  \u003cli\u003e4.500 inch barrel length provides extended contact surface area\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch stud hole for secure mechanical connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 500 kcmil copper conductors only in medium-voltage electrical systems rated up to 35 kV.

De-energize and verify absence of voltage on the circuit before beginning any termination work. Use a properly calibrated compression tool rated for the lug size to ensure a full, uniform crimp. Avoid over-crimping or under-crimping, as improper compression can compromise conductivity and mechanical integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Type\u003c\/strong\u003e: Copper only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 500 kcmil\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\u003eStud Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.836 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length\u003c\/strong\u003e: 4.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Seamless high-conductivity copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 7000031405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346959368498,"sku":"7000031405","price":331.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535384.jpg?v=1782095219","url":"https:\/\/voomisupply.com\/products\/3m-7000031405-copper-long-barrel-lug-500-kcmil-35-kv","provider":"Voomi Supply","version":"1.0","type":"link"}
