TST Seal Brand Story
—The Mission of a Cable—
In 2008, a blizzard paralyzed the power grid in a mountainous area of China. Traditional cables broke due to low temperatures, and emergency repairs were in trouble. Founder Pan led the team to work non-stop for 72 hours to develop -50℃ antifreeze cables and pipe sealing modules, which were sent to the disaster area overnight to restore power supply. This crisis made the team deeply aware that cables are not only commodities, but also the bond that carries life.
Since then, the company has anchored the research and development direction of “special cable pipe sealing modules for extreme environments”. From the permafrost of the Qinghai-Tibet Plateau to the high-temperature oil fields at the equator, from the deep sea of 10,000 meters to the interior of spacecraft, TST SAEL cables protect human exploration of energy with extreme performance. As the brand slogan says-“Wherever, Whenever, We Connect.”
