Brass Parts India is a leading manufacturer and exporter of Copper Lugs and Copper Tubular Lugs from Jamnagar, India — supplying OEMs, electrical contractors, utilities, and distributors across the USA, Canada, and worldwide. Our copper lugs are precision-manufactured from high-conductivity electrolytic copper (99.9% pure), delivering maximum electrical performance, corrosion resistance, and long service life in even the most demanding environments.
Whether you need standard DIN-type cable lugs, NEMA-compliant tubular lugs, compression lugs, or custom-engineered copper terminations, Brass Parts India delivers consistent quality at competitive ex-works pricing — typically USD 0.20 to USD 4.50 per piece depending on barrel size and configuration, CIF US seaport.
What Are Copper Lugs and Copper Tubular Lugs?
A copper lug (also called a cable lug or wire lug) is an electrical termination device used to connect copper cables to equipment terminals, busbars, switchgear, transformers, and earthing systems. The barrel accepts a stripped cable end, which is then crimped or soldered, while the palm/tongue is bolted to the terminal. Copper tubular lugs are the cylindrical barrel-type variant — the most common form used globally for medium and heavy cable terminations.
Types of Copper Lugs We Manufacture
Copper Tubular Cable Lugs (Ring Type)
Standard ring-tongue tubular lugs with single or double barrel hole. Available in conductor sizes from 1.5 mm² up to 630 mm² (AWG 16 to 1500 kcmil). Hole diameters: M4 through M16. Manufactured per DIN 46235, BS 4579, and equivalent ANSI/UL standards. Used extensively in power distribution panels, MV/LV switchgear, and solar PV installations.
Long Barrel Copper Lugs
Extended barrel length for enhanced crimping grip and superior pull-out resistance. Preferred for vibration-prone environments such as marine, rail traction, and industrial motor connections. Barrel lengths up to 120 mm available.
Copper Compression Lugs (Indent Type)
Designed for hydraulic or mechanical indent crimping tools. Multiple indent zones for secure multi-point compression. Widely used by US utilities and electrical contractors following NEMA CC1 or ANSI C119.4 guidelines.
Copper Bi-Metallic Lugs (Copper–Aluminum)
Friction-welded bi-metallic lugs with an aluminum barrel for aluminum cables and a copper palm for copper equipment terminals — eliminating galvanic corrosion at the joint. Essential in modern power utility and solar farm wiring where mixed cable materials are used.
Tinned Copper Lugs
Electroplated with a uniform tin layer (5–15 µm) for enhanced corrosion resistance in coastal, marine, and chemical environments. Also improves solderability and prevents oxidation during storage.
Copper Pin / Ferrule Lugs
Pin-type end sleeves (ferrules) for terminating flexible stranded cables into screw terminals and circuit breakers. Available with and without insulation collars. Produced per DIN 46228 Parts 1–4.
Copper Fork / Spade Lugs
U-shaped tongue for connections that require quick connect/disconnect without fully removing the bolt. Used in battery terminals, bus connections, and grounding applications.
Heavy-Duty Copper Lugs for Transformers and Busbars
Thick-walled lugs for transformer LV/HV bushings and busbar connections — conductors from 150 mm² to 1200 mm². Dual-hole palm configurations available per customer drawings.

Frequently Asked Questions
Q1: What is the difference between a copper lug and a copper tubular lug?
A: A copper lug is the general term for any copper cable termination fitting. A “tubular lug” refers specifically to the ring/tongue type with a cylindrical barrel — the most common form. Most people use the terms interchangeably.
Q2: What copper grade do you use?
A: We primarily use C11000 (ETP Copper / CW004A) with ≥99.9% copper and conductivity ≥100% IACS. For premium applications we supply C10200 (oxygen-free copper). All material comes with mill test certificates.
Q3: Do your copper lugs comply with UL and NEMA standards?
A: Our lugs are manufactured to meet dimensional and material requirements of UL 486A-486B and NEMA CC1. We can support formal third-party certification pathways per customer requirements.
Q4: What is your minimum order quantity?
A: For standard sizes: 500–1,000 pieces per size. For custom/non-standard lugs: 1,000 pieces minimum. Trial orders are welcome for new customers.
Q5: Can you supply tinned copper lugs?
A: Yes. Electro-tin plating (5–15 µm) is available on all standard and custom lug sizes. Tinned lugs are preferred for marine, coastal, and chemical plant environments.
Q6: What are your lead times to the USA?
A: Standard sizes: 3–4 weeks. Custom/large-volume: 5–7 weeks. Sea freight from Jamnagar/Mundra to US East or West Coast ports: 18–25 days. Air freight available for urgent requirements.
