1. Spacing Maintenance

It keeps jumpers at a fixed distance, preventing them from contacting or colliding with each other under the influence of wind or other external forces. This ensures the electrical insulation between jumpers and avoids short-circuit risks caused by physical contact.

2. Lightweight Structure

Typically made of aluminum alloy and other lightweight materials, it reduces the overall weight of the transmission line while offering excellent corrosion resistance. This design not only facilitates high-altitude installation but also enhances the durability of the equipment in harsh outdoor environments.

3. Convenient Installation

Some FJZ jumper spacers adopt installation methods such as preformed strands, which feature simple operation, large contact area, and uniform adhesion distribution. These characteristics provide strong grip strength and prevent slippage, significantly improving construction efficiency and reducing the difficulty of high-altitude operations.

1. Enhanced Line Safety

By preventing friction between jumpers and contact between jumpers and tower components, it reduces the probability of faults such as short circuits, ensuring the safe and stable operation of power lines. This mechanical isolation is critical for maintaining the electrical insulation integrity of the system.

2. Extended Service Life

Minimizing damage caused by collisions and friction helps prolong the lifespan of jumpers, thereby reducing line maintenance costs. The reduction in mechanical wear also decreases the frequency of component replacements, improving the overall economy of the power system.

3. Strong Adaptability

It can adapt to different environmental conditions (e.g., high humidity, salt fog, high altitude) and line layouts, making it suitable for transmission lines of various voltage levels—from medium-voltage distribution networks to ultra-high voltage (UHV) systems. This versatility ensures wide applicability in diverse power grid scenarios.

1. Maintaining Jumper Position

It keeps a safe distance between the jumper and the tower body, preventing collisions or contact that could cause arcs and short circuits. This mechanical separation is crucial for ensuring electrical insulation and avoiding catastrophic faults in high-voltage systems.

2. Tension Balancing

By balancing the tension of jumpers in each phase, it prevents excessive swinging caused by unbalanced tension, which could lead to jumper damage or breakage. This function stabilizes the mechanical state of the jumper, reducing stress on connection points and extending service life.

3. Wind Deflection Angle Limitation

It restricts the wind deflection angle of jumpers, ensuring that the swing amplitude under wind load does not exceed specified limits. This prevents collisions between jumpers and surrounding objects (e.g., tower structures, other conductors), maintaining the geometric stability of the line under dynamic loads.

4. Auxiliary Installation and Maintenance

During installation and maintenance, it can be used as a temporary tool to fix jumpers, facilitating operator handling. This feature improves construction efficiency by providing a stable anchor point for adjusting jumper position and tension, while reducing the risk of high-altitude operation accidents.
