SC 70 LONG COPPER CABLE LUG – SECURE CONNECTION, STABLE POWER TRANSMISSION ⚡

SC 70 long copper cable lug is widely used in industrial and residential electrical systems. With its extended barrel design, this lug increases crimping surface area, ensuring strong electrical contact and minimizing heat generation during operation.

👉 Designed for connecting 70mm² power cables to:

  • Copper busbars

  • Terminal blocks

  • MCCB

  • Electrical switching devices inside control panels

Suitable for both medium-voltage and low-voltage systems.

🏭 PRACTICAL APPLICATIONS

In main distribution boards and power cabinets, 70mm² cables are commonly used for main feeder lines or high-load branches. Connection points are critical areas where overheating can occur if the crimp is insufficient.

The 41mm long barrel of SC 70 provides:

✔ Increased crimping surface for stronger grip
✔ Lower contact resistance
✔ Reduced risk of arcing
✔ Stable long-term performance

Commonly installed in:

  • Main power distribution panels

  • ATS cabinets

  • Capacitor banks

  • Motor control centers (MCC)


🛠 HOW TO SELECT THE RIGHT SC 70 LONG LUG

To ensure safe and reliable installation, check the following:

✅ Correct cable size: 70mm²
✅ Correct bolt hole diameter: Ø8.5mm (M8 bolt)
✅ Confirm equipment terminal hole size before ordering
✅ Use proper 70mm² hydraulic crimping die
✅ Avoid using oxidized or deformed lugs
✅ Tighten bolts to proper torque after installation

📌 Quick installation checklist:

  • Proper cable stripping length

  • Clean conductor surface

  • Full crimp compression achieved

  • Secure mechanical fastening


⚠ COMMON MISTAKES & HOW TO AVOID THEM

1️⃣ Using the wrong crimping die → Loose connection and overheating
2️⃣ Selecting incorrect cable size → Reduced current capacity
3️⃣ Insufficient bolt tightening → Risk of arcing
4️⃣ Short stripping length → Incomplete crimp area
5️⃣ Low-quality lugs → Fast oxidation and poor conductivity

Solution: Always verify the model SC-70 Long and confirm specifications before installation.
