Question

Can I substitute a tube ТТШ with a common ТУТ made by KBT?

Answer

TTШ is a special type o tubing designed for the insulation of the busbar. It is made of special polymer composition with tracking-resistance, has a thicker wall ( 2.0 mm and 3.7 mm) and can work for bigger voltage -10 and 35 kV correspondingly. That is why these tubes can be sued for insulation of alum and copper busbar inside high voltage distributors and can also be installed outside. Common ТУТ tube made by KBT can't be sued for voltage more than 690 V.
