Tesmec offers a complete line of machines and equipment dedicated to Earth Wire and OPGW installations and reconductoring. The full and customized package for live line OPGW reconductoring can be used as a safety system in case of road and rail crossings. All the products are designed according with IEC TR 61328, ensuring the top level of safety, reducing all the risks for operators and preventing conductor damages.

Puller & Tensioner: Solution for new lines
The grooves are made of high resistance nylon sectors, according to IEC TR 61328. This hard surface has several advantages that prevent damages on the OPGW, the most important are:

Low torsional stress resulting in no birdcaging risk.
Smooth self-alignment of the cable at the bottom of the groove.
No need to change conductor reeving direction according to cable formation.
