1. High-Quality Materials

Typically extruded from pure aluminum with excellent ductility (such as L2 grade), some models may incorporate steel and aluminum tubes, offering high strength and good electrical conductivity. The aluminum ensures low electrical resistance for efficient current transmission, while the steel enhances mechanical stability, making it suitable for high-tension overhead line applications.

2. Smooth Surface

The product features a smooth and rounded surface, which not only improves its aesthetic appeal but also reduces corona loss and surface corrosion. The polished finish minimizes air ionization around high-voltage conductors, lowering energy dissipation and extending the service life in outdoor environments exposed to moisture, salt spray, or industrial pollutants.

3. Tight Connection

Through the hydraulic butt-joint method, the compression sleeve forms a close fit with the conductor, creating reliable electrical and mechanical connections. The hydraulic pressure applied during installation deforms the sleeve to tightly grip the conductor strands, eliminating gaps and ensuring low contact resistance. This method meets stringent standards for mechanical pull-out strength and electrical continuity, critical for maintaining system reliability in power transmission networks.

1. Excellent Electrical Performance

With low joint resistance (generally no more than 1.1 times the resistance of an equal-length conductor),It effectively reduces power loss and ensures smooth current flow. The low-resistance design minimizes heat generation at the connection point, maintaining high efficiency in power transmission systems, especially for high-voltage overhead lines.

2. High Mechanical Strength

The mechanical strength of the joint is not less than 90% of the conductor’s rated tensile strength, enabling it to withstand the tension of conductors in overhead power lines and ensure safe and stable line operation. This robust mechanical performance is critical for resisting environmental stresses such as wind, ice loads, and thermal expansion/contraction.

3. Corrosion Resistance

Aluminum materials exhibit good corrosion resistance, making them suitable for various natural environments and extending the service life of the transmission lines. The corrosion-resistant properties reduce maintenance needs and enhance the long-term reliability of the power infrastructure.

4. Reliable Installation Quality

The hydraulic butt-joint process is relatively mature, with minimal impact from human factors during installation. Following standard operating procedures ensures consistent and reliable installation quality, reducing the risk of faulty connections. This standardized approach is widely recognized in power engineering for its precision and dependability in creating secure conductor joints.

1. Conductor Jointing

Primarily used for jointing conductors such as steel-core aluminum stranded wires in overhead power lines, enabling the extension and connection of conductors to ensure seamless electricity transmission between wire segments. This is critical for maintaining continuous power flow in long-distance transmission networks.

2. Tension and Current Bearing

While bearing the tension of the conductors, it ensures excellent electrical conductivity, allowing stable and continuous power transmission to various locations. The design balances mechanical robustness and electrical reliability , making it an essential component for secure and efficient power distribution.
