T Copper Tube Terminals

Precision Connection, Maximum Protection – Engineered for Harsh Electrical Environments

✅ Pre-Insulated Nylon Sleeve
High-density Nylon sleeves pre-crimped onto terminals, withstand -20°C to +80°C, resisting oil, moisture, and vibration. No heat shrink needed – 50% faster installation.

✅ Military-Grade Conductivity
Tin-plated brass core, conductivity ≥28%. Tested at 20A continuous current, crimping resistance ≤0.5mΩ.

✅ Anti-Mismatch Color Coding
Red/blue/yellow sleeves follow industry polarity standards, reducing misconnection risks by 90%.

✅ 3-Second Crimping
Streamlined bullet shape works with standard crimpers (AWG 22-10). Solder-free, reliable connection in 3 seconds.

PRODUCT DESCRIPTION

T-shaped copper tube terminals (also known as T-type copper wire lugs) are electrical transition components used for efficient connections between copper conductors and device terminals. Their 'T' shaped structure provides both horizontal and vertical wiring channels and is widely used in busbar connections for multi-branch circuits, power distribution systems, industrial control cabinets, rail transit, and construction projects, enabling safe and reliable power transmission and signal transfer.The main purpose is to achieve standardized connections between wires and electrical equipment (circuit breakers, contactors, terminal blocks); to construct trunk and branch line junctions within distribution boxes/cabinets; to enhance high current carrying capacity, long-term connection stability, and to enable transition connections between wires of different gauges. The surface treatment process is tin plating, which is anti-oxidation and corrosion-resistant, suitable for humid environments.
