Transmission line cable fittings are essential connection components engineered to ensure safe, reliable, and efficient power transmission in electrical distribution systems. These critical components enable firm electrical connections between different conductors and equipment, resolving common compatibility and performance challenges in power distribution networks.
Widely applied in copper-aluminum transition connections and direct conductor-to-conductor connections, they offer robust solutions for various wiring configurations, including round, semi-circular, and fan-shaped conductors. Manufactured from premium-grade materials with advanced production techniques, they deliver outstanding electrical conductivity, high mechanical strength, and strong resistance to galvanic corrosion.
Our cable fittings comply with strict industry quality standards, delivering stable performance and a long service life, making them the preferred choice for power distribution infrastructure projects requiring high reliability.
DTL, DT, and DL series copper-aluminum terminals are designed for reliable transition connections between round, semi-circular, and shoulder-shaped aluminum conductors, power cables, and copper terminals of electrical equipment in distribution systems, effectively solving compatibility problems arising from dissimilar metal conductors.
A full range of connecting tube products support direct connections for round, semi-circular, and fan-shaped wires and power cables in distribution installations. The product lineup includes GT series oil-blocking and straight-through copper connecting tubes, GL series oil-blocking aluminum connecting tubes, and GTL series copper-aluminum connecting tubes, suitable for conductors of different materials and structures.
We strictly select high-quality raw materials for production. Aluminum parts adopt L2 and L3 grade aluminum, while copper parts use T2 copper, ensuring stable material properties and laying a solid foundation for long-term connection reliability.
We adopt a variety of advanced manufacturing technologies. DTL and GTL series products apply friction welding technology; GT series oil-blocking tubes are precision-machined from T2 copper bars, and straight-through tubes are stamped from T2 copper pipes. Mature and precise production processes guarantee consistent product quality.
Friction welding achieves high welding strength, superior electrical conductivity, and excellent resistance to galvanic corrosion, greatly extending product service life. GT, GL, and GTL series connecting tubes maintain stable performance for long-term conductor connection operation.
Our complete cable fitting product portfolio covers multiple connection applications, including copper-aluminum transition joints and same-metal conductor joints. Compatible with round, semi-circular, and fan-shaped wires and power cables, this portfolio fully meets diverse connection demands in distribution systems.
