Description
WH CC Copper Cable Lug SCA(JGK) Heavy-Duty Electro-Tinned Compression Terminal (1.5mm² to 630 mm²) Excellent Power Cable Termination for Exceptional Reliability
The CC SCA(JGK) Copper Cable Lug series provides a heavy-duty, high-conductivity crimp termination solution engineered specifically for copper conductor cables in power distribution and electrical equipment assemblies.
Designed to establish a seamless mechanical and electrical connection between multi-strand power cables and electrical apparatus studs, these tubular cable lugs ensure efficient electrical power transfer with minimal resistance and voltage drop.
Manufactured from high-purity electrolytic grade copper (T2/Cu > 99.9%), each lug undergoes precision seamless extrusion to maintain structural strength across its entire length.
The outer surface is electro-tinned to provide superior protection against atmospheric oxidation, chemical corrosion, and galvanic degradation over extended operational lifespans.
This makes the SCA(JGK) series highly suitable for harsh industrial plants, marine environments, outdoor switchgear panels, and main power distribution boards.
Key structural and functional advantages of the CC SCA(JGK) Cable Lug series include:
-
High-Purity Copper Construction: Built from seamless copper tube ensuring optimal conductivity, high mechanical strength, and structural integrity during heavy crimping.
-
Electro-Tinned Surface Protection: Tin-plated finish prevents oxidation and maintains low contact resistance in high-humidity or corrosive industrial settings.
-
Precision Internal Chamfering: Features a smooth bell-mouth or chamfered barrel entrance for effortless insertion of fine and multi-stranded copper conductors.
-
Extensive Size Matrix: Available in 19 core cable cross-section models ranging from 1.5 mm² up to 630mm² with multiple stud hole options (D), barrel inner diameters (d), barrel outer diameters (D), total lengths (L), and wall thicknesses (S).
Whether completing connections on main circuit breakers, transformer bushings, busbar links, or commercial distribution panels, the CC SCA(JGK) Copper Cable Lug series ensures dependable electrical safety and termination performance

Frequently Asked Questions (FAQ)
Q1: What does the designation SCA(JGK) mean?
A : SCA(JGK) refers to a standard series of electro-tinned tubular copper cable lugs designed for compression crimping onto copper cables.
The number following the item code (e.g., SCA(JGK)-50) indicates the cross-sectional cable conductor size in mm².
Q2: Why is electro-tin plating important for copper cable lugs?
A : Bare copper reacts with oxygen and ambient humidity to form non-conductive copper oxide.
Electro-tin plating creates a protective chemical barrier that prevents oxidation, inhibits galvanic corrosion when connected to metallic terminals, and preserves low electrical contact resistance.
Q3: How do I select the right stud hole size (D) for my application?
A : The stud hole diameter ($D$) corresponds to the bolt size on your switchgear or busbar:
-
6.4 mm: M6 bolt
-
8.4 mm: M8 bolt
-
10.4 mm: M10 bolt
-
12.4 mm: M12 bolt
-
16.4 mm: M16 bolt
-
20.5 mm: M20 bolt
Q4: Can aluminum conductors be crimped into these copper cable lugs?
A : No. Directly connecting aluminum conductors to copper lugs causes bimetallic galvanic corrosion, which degrades the electrical joint.
These lugs are specifically designed for copper cables. For aluminum cables, bimetallic (DTL) cable lugs should be used.
Q5: What crimping tools should be used to install SCA(JGK) cable lugs?
A : For small cable sizes (1.5mm² to 10 mm²), standard mechanical ratchet crimping pliers are suitable.
For sizes 16 mm² and above, use a calibrated hydraulic crimping tool with hexagonal dies matching the specified outer barrel diameter (D) to achieve maximum compaction and pull-out strength.
