Product Features & Engineering Logic
| Key Area | Feature | Advantage | Benefit |
| Mechanical Strength | 32mm Extra-Deep Barrel. | Provides 100% more surface area for crimping compared to standard SC lugs. | Maximum Safety: Significantly increases wire pull-out resistance, ensuring connections never fail under mechanical stress or vibration. |
| Electrical Integrity | Seamless T2 Copper Body. | Ensures uniform current distribution and zero risk of the barrel opening during high-pressure crimping. | System Efficiency: Maintains a low-resistance path, reducing voltage drop and preventing heat-related power loss. |
| Corrosion Defense | Full Electro-Tin Plating. | Acts as a sacrificial barrier against moisture, acids, and salt spray. | Longevity: Extends the service life of your electrical infrastructure, even in harsh marine or industrial environments. |
| Precision Sizing | Exact 12.6mm OD / 9.8mm ID geometry. | Perfectly matches the stranded profile of 1/0 AWG (50mm²) cables. | Reliable Crimp: Eliminates internal air pockets, creating a gas-tight bond that protects copper strands from aging. |
FAQs
Q1: What is the main advantage of the TPE series over the SC series?
The TPE series features a 32mm barrel, which is twice as deep as standard SC series lugs (typically 16mm for this wire size). This allows for three or even four crimp points, providing the highest possible pull-out strength for heavy-duty industrial or mobile applications.
Q2: Are these lugs suitable for marine use?
Yes. The 99.9% copper body is fully tin-plated. This plating prevents the copper from reacting with salt air and moisture, which is the leading cause of terminal failure and “green death” corrosion in marine wiring.
Q3: What type of tool should be used for the TPE50 series?
Due to the seamless thick-wall copper and the 32mm barrel depth, we recommend using a hydraulic crimper with a 50mm² hex die. This ensures enough pressure is applied across the entire deep-barrel surface to create a gas-tight electrical bond.
