The Copper Tube Terminal (SC-Type) is an essential heavy-duty electrical connector designed for terminating large-gauge power cables and securely connecting them to electrical appliances, distribution blocks, and batteries. Whether you are assembling complex switchgear or wiring industrial machinery, a reliable termination is critical to preventing electrical resistance and dangerous heat buildup.
The Copper Tube Terminals of 1.5 mm²to 500 mm²copper conductors are made of copper 99.9%.
As standard, we manufacture tube terminals through connectors (type SC), but also custom connectors in large quantities. The Unique electric fits IEC 62321 stranded conductors.
Our SC-Type Copper Tube Terminals feature a terminal body forged from high-purity copper, ensuring maximum current flow and strong conductivity. To combat harsh environments and prevent oxidation, each terminal undergoes a professional tin plating process. Known for their thickened material and inspection hole design, these premium copper lugs guarantee a secure, low-resistance connection that meets the strict safety demands of modern electrical engineering.

In our standard range, there are Copper Tube Terminals with one or two holes.
In addition, there are straight-through connectors for service and road lighting cables and pipe terminals. Normally, one crimp needs to be 150 mm²and two or three crimp needs more cross-sectional area.
Before crimping, check the recommended crimping quantity on the package label.
Because of their rugged construction and high-current capacity, SC-Type Copper Tube Terminals are widely used across heavy-duty electrical sectors:
Power Distribution: Terminating thick main feeder cables in low and medium voltage switchgear cabinets.
Renewable Energy: Connecting large battery banks and inverters in solar and wind power storage systems.
Industrial Machinery: Providing vibration-resistant power connections for heavy CNC machines and factory automation equipment.
Automotive & Marine: Splicing heavy-duty battery cables and grounding wires in commercial vehicles and marine vessels.
Our Copper Tube Terminals are designed for convenient installation ensuring a professional result every time:
Cable Preparation: Strip the insulation off the end of your heavy-duty cable, matching the length of the terminal’s barrel.
Insertion & Inspection: Insert the bare copper strands into the terminal. Use the inspection hole at the base of the barrel to confirm the wire is fully seated against the end.
Hydraulic Crimping: Use a heavy-duty hydraulic crimping tool with the appropriate die size to tightly compress the thickened copper barrel around the wire.
Bolting: Slide the flat ringed end over your mounting stud and secure it tightly with a nut and washer.
Unmatched Durability: Our Copper Tube Terminals use thickened material to prevent crimp failure, ensuring your connections are safe and permanent.
One-Stop Procurement: With complete specifications covering the entire SC series (from SC4-5 to SC400-20), you can source all your terminal needs from a single, reliable supplier.
Tailored Engineering: If our standard sizes do not fit your specific application, our factory can manufacture custom non-standard products exactly to your blueprints.
Factory-Direct Value: By purchasing directly from the manufacturer, you receive premium, high-conductivity electrical components at highly competitive wholesale prices.
