DTL-2-120 Copper-Aluminum Bimetal Lug – Reliable Connection for 120mm² Aluminum Cable 🔌

I. Introduction to DTL-2-120 Bimetal Lug 📌

DTL-2-120 bimetal lug is a high-demand bi-metal (Cu–Al) connector designed to terminate 120mm² aluminum cable onto copper terminals or copper busbars in electrical systems.

Built to support stable contact performance, this lug helps reduce the chance of overheating at the joint when the correct crimping method and bolt tightening are applied.

II. Technical specifications of DTL-2-120 📋

(See the detailed table below. If you need exact barrel diameter (D), overall length (L), thickness (T) based on your batch, please provide them so we can publish 100% accurate dimensions.)

III. Key advantages of DTL-2-120 🌟

🔋 Stable current transfer: Supports a firm connection between aluminum conductors and copper equipment, helping reduce contact resistance.
🛠️ Easy installation: Designed for proper crimping with suitable dies, minimizing deformation when installed correctly.
🛡️ Helps resist oxidation/corrosion: Bimetal structure supports longer-lasting performance in industrial environments.
🏗️ Wide applications: Works well in switchboards, substations, factories, and many heavy-duty electrical projects.


IV. Real-life applications 🏗️

In industrial electrical installations, connecting aluminum cable to copper terminals/busbars is a sensitive point because mixed metals can increase contact resistance if done incorrectly. DTL-2-120 is commonly used for 120mm² aluminum cable runs that need to terminate into MCCB/ACB terminals, copper busbars, capacitor banks, distribution boards, and substation panels.

It is also suitable for long-term operations in factories, commercial buildings, pumping stations, and expansion projects where stable load performance is required. When you choose the correct lug code + bolt-hole size + proper crimping, the joint stays tight, reduces local heating risks, and makes periodic maintenance checks easier.

V. How to choose the correct DTL-2-120 ✅

Use the checklist below to avoid wrong selection and rework:

  1. 🔎 Cable size: must match 120mm² (do not estimate).

  2. 🕳️ Bolt-hole size: 13mm hole for matching bolts/studs.

  3. ⚙️ Series type: ensure it is DTL-2 (geometry may differ vs. other series).

  4. 🛠️ Crimp tool & die: use the correct die for 120mm² to ensure strong compression.

  5. 🧴 Anti-oxidation compound: consider if the project procedure requires it for aluminum conductors.

  6. 📍 Environment: humid/corrosive areas need better sealing and scheduled retightening checks.

  7. 📦 Documentation needs: confirm CO/CQ & VAT invoice if required by your project.

✅ Quick order checklist:

  • Aluminum cable: 120mm²

  • Bolt hole: 13mm

  • Correct series: DTL-2

  • Correct crimp die for 120mm²

  • CO/CQ – VAT required (if any)


VI. Installation / crimping guide 🛠️

  1. ✂️ Strip insulation to match the lug barrel length (avoid over/under stripping).

  2. 🧽 Clean and dry aluminum strands; remove dust/oil for better contact.

  3. 🧴 (If required) apply anti-oxidation compound per your site procedure.

  4. 🔩 Insert the conductor fully into the barrel and align straight.

  5. 🛠️ Crimp using the correct die and required crimp points per tool guideline.

  6. 🔧 Bolt onto the copper terminal/busbar using suitable hardware for a 13mm hole; tighten properly.

  7. ✅ Final check: no cracks, no misalignment, clean contact area; monitor temperature at the joint if possible.


VII. Common mistakes & how to avoid them ⚠️

Wrong bolt-hole size: causes loose fit or forced drilling → always verify the stud/bolt size first.
Wrong die / weak crimp: leads to high resistance and heating → use the proper 120mm² die.
Incorrect stripping length: exposed strands or insufficient contact → match barrel length.
Dirty/wet contact surfaces: increases resistance and oxidation → clean and keep dry before crimping.
Over/under tightening bolts: loose joints heat up; excessive torque may deform → tighten to appropriate torque.
Skipping periodic inspection: heavy-current joints need scheduled checks → include in maintenance plan.


VIII. Frequently Asked Questions (FAQ) ❓

  1. What cable size is DTL-2-120 for?
