Braced Posts

Braced Line Post

Braced Line Post

A braced line post insulator uses a conventional line post with a suspension string tied to the tower face. Some of the characteristics of a braced line post are:

  • It uses a traditional fixed base line post.
  • The longitudinal strength is limited to the RCL rating of the line post component.
  • It generates high tower torque (Z-direction) under longitudinal loading.

Horizontal-V

Horizontal-V

A horizontal-V insulator uses a conventional line post with a suspension string at a fixed offset extending from the tower face, adding a stabilizing force to the assembly. Some of the characteristics of a horizontal-V assembly are:

  • It uses a fixed base horizontal line post (zero degree upsweep).
  • It has an inclined hinge axis to add resistance to longitudinal movement.
  • It employs a suspension insulator ground end stub arm (vang).
  • The longitudinal strength is limited to the RCL rating of the line post component.
  • It generates high tower torque (Z-direction) under longitudinal loading.

Pivoting Horizontal-V

Pivoting Horizontal-V

A pivoting horizontal-V insulator uses a conventional suspension string with a line post insulator fastened to the structure with a hinged base. Some of the characteristics of a pivoting horizontal-V are:

  • It pivots about an inclined axis.
  • It employs a suspension insulator ground end stub arm (vang).
  • It uses a universal joint or pivot base on the strut.
  • It has high longitudinal strength.
  • It generates low tower torque (Z-direction) under longitudinal loading.
  • The assembly's swing angle is a function of the vertical load and the tower offset pivot angle.
  • The assembly's maximum longitudinal loading is a function of the tensile rating of the strut.
