Grooved tube for ESP motors
The tube is intended for use in DC/AC electric machines (including electric motors that drive submersible units operated in wells for oil production and reservoir pressure maintenance systems), as well as in electrical and radio engineering products operating in aggressive environments and in the temperature range of minus 60 to plus 200 °C.

The tube is available in two types:
- TP – grooved tube with wall thickness of up to 0.27 mm
- TI – insulating tube with a wall thickness of 0.34 mm and above
