Inter-phase composite spacer is used at compact lined with high insulation performance and mechanical strength. It connects all the conducting wire, which restrict one another to prevent from moving. It improves the safety and reliability of the power grid.

Composite phase spacers for compact high-voltage transmission lines, can effectively control the line phase distance to maintain safety and reduce transmission corridor space, reduce the line-building investments. Composite phase spacers has a good anti-bending, strong impact, shock and anti-brittle performance, light weight, easy installation, maintenance-free, without manual cleaning, be widely used.
