Description
WH CC Cable Link GTY-1 Electro-Tinned Copper Tubular Compression Splice (1.5mm² to 400 mm²) Excellent Power Cable Through-Connector for Exceptional Reliability
The CC GTY-1 Copper Cable Link series provides a heavy-duty, high-conductivity straight-through compression splicing solution engineered specifically for joining copper conductor cables end-to-end in power distribution and electrical wiring applications.
Designed to establish a continuous mechanical and electrical joint between two copper cables, these tubular copper links allow power lines to be extended or repaired with minimal electrical resistance and minimal voltage drop.
Manufactured from high-purity electrolytic seamless copper tubing, each cable link is built to maintain structural integrity under heavy crimping forces.
The surface is fully electro-tinned to prevent copper oxidation, chemical degradation, and surface corrosion when exposed to high humidity or harsh industrial environments.
Each link features an integrated internal wire stop (center dimple/barrier) that ensures both conductor ends are inserted to equal depths, guaranteeing balanced current distribution and optimal mechanical grip across the splice barrel.
Key structural and functional features of the CC GTY-1 Cable Link series include:
-
High-Purity Copper Construction: Drawn from seamless copper tube ensuring maximum electrical conductivity and strength during mechanical compression.
-
Electro-Tinned Surface Protection: Tin plating protects against atmospheric oxidation and maintains low contact resistance over long service periods.
-
Integrated Center Wire Stop: Center dimple design ensures equal conductor insertion depth for both cable ends.
-
Comprehensive Range of Sizes: Available in 17 distinct sizes covering conductor cross-sections from 1.5mm² up to 400mm² with precise outer diameters (D), inner diameters (d), and total lengths (L).
Whether performing inline cable joints, underground power line extensions, or switchgear wiring repairs, the CC GTY-1 Cable Link series ensures safe and durable electrical connectivity.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of a GTY-1 copper cable link?
A : A GTY-1 cable link is a straight-through tubular connector used to join two copper cables end-to-end. It allows for wire extensions, repairs of damaged cable sections, or inline splicing without requiring screw terminals.
Q2: What is the purpose of the dimple/stop in the middle of the GTY-1 link?
A : The center stop dimple prevents stripped wires from passing through to the opposite side. This ensures that both inserted copper cables occupy exactly 50% of the barrel length ($L/2$), providing equal mechanical contact and balanced electrical conductivity across the joint.
Q3: Why are GTY-1 copper cable links electro-tinned?
A : Bare copper oxidizes over time, producing a non-conductive layer that increases joint resistance and heat.
Electro-tin plating creates a protective barrier against oxidation, moisture, and chemical exposure, preserving low electrical contact resistance throughout the splice lifetime.
Q4: Can GTY-1 copper cable links be used to join aluminum wires?
A ; No. Connecting aluminum wires directly to a copper link causes galvanic corrosion due to dissimilar metal contact, leading to joint degradation.
GTY-1 links should strictly be used with copper conductors. For aluminum-to-aluminum joints, aluminum links (GL) should be used, and for copper-to-aluminum joints, bimetallic links (GTL) are required.
Q5: What crimping tools should be used for installing GTY-1 cable links?
A : For small sizes (1.5 mm² to 10mm²), standard mechanical ratchet crimping pliers work well.
For sizes 16mm² and above, a calibrated hydraulic crimping tool with hexagonal dies matching the specified outer diameter (D) should be used to ensure full compaction and maximum pull-out strength.
