Triangular Emergency Tower - TET
SPEED, ECONOMY AND STRENGHT FOR LINES UP TO 1200 kV
Expertise
Since the 80´s, Seccional Team has been designing & manufacturing Emergency Towers, called Emergency Restoration System (ERS). In 2007 developed the TET Triangular Emergency Tower, made of weathering steel that can be quickly deployed to restore power on damaged transmission lines of up to 1200 kV.
Versatility
The same structure can be used as a suspension, anchorage or chainette tower just by changing the guys cables quantity and position. These towers require no heavy equipment, no concrete foundation and a team of 6 linemen working for a few hours
Maintenance Tool
They are also used for temporary needs such as construction by-passes, river crossing or temporary lines to remote locations.
High Strenght
Designed for high loads, for lines up to 1200kV.
Ficha técnica
Tecnology security
Seccional offers the best in precision engineering to meet the most demanding requirements of the market, including Finite Element Analysis through a proprietary software that was validated by the Concurrent Engineering Research and Development Laboratory (NuPES) of the Federal Center for Education in Technology of Parana and Universidade Positivo.
Wind tunnel analysis were performed at the Prof. Joaquim Blessmann boundary layer wind tunnel, located in the Laboratório de Aerodinâmica das Construções (LAC) of the Universidade Federal do Rio Grande do Sul (UFRGS, Brazil validating the superior behavior of Seccional solutions.
Seccional performs full-scale prototype testing on a wide variety of structures including poles, guyed towers and self-supporting towers simulating the conditions and variables that concern the client most. TECPAR Technological Institute of Parana, LACTEC Labs besides other certified test stations have successfully performed the tests approving Seccional solutions.
