ACL
Mingxu
The ACL copper-aluminum terminal is a high-performance bi-metallic connector purpose-built for reliable electrical connections in molded case circuit breakers (MCCBs), switchgear, and power distribution systems. Its seamless copper-aluminum transition joint eliminates galvanic corrosion risks, ensuring stable current transmission and minimal contact resistance over decades of service.
Key Features & Benefits:
Dual-Material Construction: Aluminum barrel accommodates 10–630 sqmm aluminum cables, while the copper lug end provides optimal conductivity for connection to copper busbars or equipment terminals.
Precision Engineering: Standardized bolt hole sizes (Ø6–Ø17) align with industry mounting requirements, and crimp depth markings ensure consistent, secure installations.
Corrosion Resistance: High purity copper lug and oxidation-resistant aluminum barrel extend service life in harsh industrial, coastal, or high-humidity environments.
Installation Guide:Strip the aluminum cable insulation to the length marked on the ACL terminal barrel.
Insert the stripped cable fully into the aluminum barrel, ensuring no exposed strands remain.
Use a hydraulic crimping tool with matching dies to compress the barrel at 2–3 evenly spaced points.
Align the copper lug’s bolt hole with the MCCB or busbar terminal, then secure with a torque-controlled bolt to meet specified torque values.
Selection Tips:
Match the terminal’s cross-sectional range (e.g., ACL-185sqmm) to your cable size.
Select a bolt hole diameter (Ø6–Ø17) compatible with your equipment’s mounting studs.
Prioritize ACL terminals for systems where aluminum cables connect to copper-based MCCBs or distribution panels.
Applications:Widely used in industrial power plants, commercial building electrical systems, renewable energy inverters, and utility distribution networks, where reliable connections between aluminum cables and copper equipment are critical.
