Composite line posts

The composite line posts are for use in the overhead distribution lines using bare or covered conductors, the composite line posts are made from a proprietary, high-density polyethylene-based compound with a dielectric constant compatible with polyethylene covered conductors.

Composite line posts

For the composite line posts, it has for different connection types, since these different types can satisfy client’s different needs:
Vertical tie-top type composite line posts
Vertical clamp-top types
Horizontal clamp top-cup base types
Horizontal clamp top gain base type

The composite line post are used for replace the structure arms of tower, it can reduce the overall size of support towers, composite line posts also can provide a tightly fix the position of the conductors in space.
The primary loading direction of concern was vertical, the composite line posts are used with a existing support structure were used as two legs of the triangle, the third leg was created by adding an upward angled brace insulator from the line end of the line post to the tower to buttress the vertical strength.

Compare with porcelain insulator the composite line posts have many advantages:
The composite line posts closely match the dielectric properties of the covered conductor jacket
UV stabilized for long-term service
High impact resistance- designed to reduce breakage and vandal shot damage, particularly at cold temperatures
Light weight design reduces shipping costs and line man handling requirements
