Construction & Materials

Premium Copper Material:
TX Copper Lugs are manufactured from high-purity electrolytic copper (99.9%), ensuring excellent electrical conductivity and low resistance. This material selection guarantees superior performance under high-current applications.

Seamless Tube Design:
Each lug is produced using a one-piece seamless construction, eliminating weak points and providing uniform wall thickness. This ensures mechanical strength, reliability, and long-term connection stability.

Surface Treatments:

  • Tin-Plated Option: Enhances corrosion resistance in harsh and outdoor environments.

  • Acid-Treated Option: Improves surface durability and adhesion for additional protection.

Precision Manufacturing:
The TX series lugs undergo precision machining to maintain exact dimensions, clean edges, and optimized barrel design. This ensures proper conductor insertion, consistent crimping, and reliable electrical connections.

Thermal & Mechanical Performance:
The T2 copper material provides excellent heat dissipation and maintains connection integrity across a wide temperature range (-50°C to +150°C). It also offers high tensile strength and resistance to creep, reducing maintenance needs over time.

Installation Guide

  1. Select Correct Size: Match the DT(G) lug to the conductor cross-section.

  2. Prepare Conductor: Clean, strip, and ensure the conductor is damage-free.

  3. Insert Fully: Slide the conductor to the barrel’s end or inspection window.

  4. Crimp Properly: Use a compatible crimping tool and die; follow the recommended sequence.

  5. Securely Mount: Apply torque using calibrated tools according to the guidelines.

  6. Protect Connections: Use joint compounds or protective coverings in corrosive environments to prevent damage.
