DTLL Mechanical Lug
Application:
Used for connecting conductors to flat-plate electrical equipment in power distribution lines with rated voltages of 35KV and below, serving as a copper-aluminum transition terminal. Suitable for aluminum and aluminum alloy conductors.
Feature:
·High Mechanical Strength: Made of high-strength aluminum alloy and T2 copper, heat-treated and welded, with a tensile strength of up to 260MPa.
·Excellent Electrical Performance: Passed 1,000 thermal cycles and 6 short-circuit tests.
·Span-Type Design: One model fits multiple cable diameters, reducing inventory requirements.
·Constant Crimping Force: Torque bolts feature a preset shear torque; the hex head automatically breaks when reached without damaging the conductor.
·Easy Installation: Can be installed using a wrench or socket wrench.
·Extended Lifespan: Oil-blocking design with internal conductive paste reduces contact resistance, resists oxidation, and prevents corrosion.
