Usage

A support where line sections are hold with strain tension sets.

  • Tension set (466-12-04) : An assembly of strain link and an anchor clamp to maintain the mechanical tension in a line/cable. Insulators are used as link in case of bare power conductors.
  • Anchor clamp (466-11-10) : A device fitting a line/cable to a strain link as to maintain the mechanical tension in the line. The clamp is at the live end of insulators in case of bare power conductors.


Corresponding supports are normally built stronger than suspension towers as they are supposed to maintain the mechanical tension in the line through tension sets and anchor clamps.
Often used as angle tower when the line changes direction. Lines often terminate on anchors even if it's not mandatory.

Although insulators are vertical here, it's an actual anchor support. Look closely to conductors vs insulators link : conductors are cut and clamped right under the insulation chain.
