Product Advantages

1.Improve line safety

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

2.Extend conductor lifespan

Reducing conductor vibration and wear helps prolong the service life of conductors and lower line maintenance costs.

3.Easy installation

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

Functional Features

It is mainly used for double-split conductor lines of 220kV and 330kV to ensure that the spacing between split conductor bundles remains unchanged, so as to meet the requirements of electrical performance and reduce the surface potential gradient. Meanwhile, in case of short circuits, it can prevent the attraction and collision between conductor bundles due to electromagnetic force, Ensuring the normal operation of power lines.
