JYD-001-3 Hydraulic lap-joint compression sleeve

1. Material Combination

Typically composed of an aluminum outer tube and a hot-dip galvanized steel inner tube, this design integrates the excellent electrical conductivity of aluminum with the high strength of steel to meet both electrical and mechanical performance requirements. The aluminum outer layer ensures low resistance for efficient current transmission, while the steel inner layer provides robust mechanical support, making it suitable for high-tension overhead line applications.

2. Tight Connection

Through the hydraulic lap-joint method, the compression sleeve forms a close and secure fit with the conductor, creating a reliable connection that effectively reduces contact resistance. The hydraulic pressure applied during installation deforms the sleeve to tightly grip the overlapped conductor strands, eliminating air gaps and ensuring stable electrical continuity. This method enhances the joint’s durability and reduces energy loss due to low contact resistance, critical for maintaining system efficiency in power transmission networks.

1. Excellent Electrical Performance

Ensures reliable electrical conductivity, enabling seamless electricity transmission between conductors and guaranteeing smooth current flow while minimizing power loss. The low-resistance design of the aluminum outer tube reduces heat generation at the joint, maintaining high efficiency in power transmission systems, particularly for high-voltage overhead lines.

2. High Mechanical Strength

The inner tube, made of hot-dip galvanized steel, offers superior strength to withstand the tension of conductors in overhead power lines, ensuring safe and stable line operation. This robust mechanical performance resists environmental stresses such as wind, ice loads, and thermal expansion/contraction, while the galvanized coating enhances corrosion resistance for long-term durability.

3. Reliable Installation Quality

The hydraulic lap-joint process is highly mature and minimally affected by human factors during installation. Following standard operating procedures ensures consistent and reliable installation quality, reducing the risk of faulty connections. This standardized approach provides precision and dependability, making it a trusted method for creating secure conductor joints in power engineering projects.

1. Conductor Jointing

Used for splicing conductors such as steel-reinforced aluminum stranded wires in overhead power lines, enabling the extension and connection of conductors. It is suitable for steel-reinforced aluminum stranded wires of various specifications, ensuring seamless electrical continuity in power transmission networks. This function is critical for maintaining uninterrupted power flow across extended line segments.

2. Tension and Current Bearing

While bearing the tensile force of the conductors, it ensures excellent electrical conductivity to enable stable and continuous power transmission. The design integrates mechanical strength and electrical reliability, making it an essential component for secure and efficient power distribution in high-voltage systems.
