FJZ-001-2 (Two-Bundle Spacer)

1.Spacing Maintenance

It can keep the double-split conductors at a fixed distance under the effects of wind force, ice load, short-circuit current, etc., preventing the sub-conductors from whipping each other.

2. Damping and Vibration Reduction

With damping characteristics, it can effectively suppress the aeolian vibration and sub-span oscillation of the conductors, reducing the vibration amplitude of the conductors.

3. Lightweight and Corrosion-Resistant Material

Generally made of aluminum and other materials, it is lightweight, convenient for installation, and can reduce the load on the line. At the same time, it has strong corrosion resistance and can adapt to harsh environments.

1. Improve Line Reliability

By preventing conductor collisions and excessive vibration, the probability of line faults is reduced, ensuring the safe and stable operation of power lines.

2. Prolong Conductor Lifespan

Reducing fatigue damage and wear caused by conductor vibration helps extend the service life of conductors and lower line maintenance costs.

3. Convenient and Efficient Installation

Some FJZ double-split spacers adopt preformed strand installation, featuring simple operation, large contact area, uniform adhesion distribution, high grip strength, and resistance to slippage.

Primarily used in 220kV and 330kV double-split conductor lines, it ensures the spacing between split conductor bundles remains constant, meets electrical performance requirements, and reduces surface potential gradient.

Electrical Performance Assurance: Maintains fixed bundle spacing to optimize electric field distribution and comply with insulation design standards for high-voltage lines.

Short-Circuit Protection: Prevents conductor bundles from attracting and colliding due to electromagnetic forces during short-circuit faults, avoiding mechanical damage and arc discharge risks.

Vibration Suppression:

Inhibits sub-span oscillations (caused by wind-induced frequency resonance between adjacent spacers).

Dampens aeolian vibrations (high-frequency low-amplitude vibrations), reducing conductor fatigue and prolonging service life.

System Stability: Ensures safe and reliable operation of power lines under normal and fault conditions by combining mechanical fixation with vibration control.
