Anti-tracking heat shrink tubes ТСТ-А - new development of the “KBT” factory. These tubes have a shrink ratio - 3:1 for insulation of the cable conductors and busbars in the panel devices and also for assembling termination and joint heat shrinkable cable kits, for voltage up to 10kV.

For the production of dual-walled heat-shrink tubes TCT (KBT) used a particular composition of the polyolefin, which gives the tube anti-tracking properties and typical brick-red color.

Anti-tracking tubes ТСТ-A are resistant to UV rays, to aggressive influence of cable oils and successfully used not only for cables with plastic, but with paper oil impregnated insulation cables as well.

Typical feature of these heat shrinkable tubes, manufactured by “KBT” factory - is calibrated uniform thickness of the walls.

In addition to the excellent dielectric properties of the material, the thickness of heat-shrink tubes TCT, more than 2.5 times thicker than similar tube ТУТ нг. With such high rate, TCT tubes have high strength and resistance to mechanical stress.

Due to the increased shrink ratio ( up to 3:1) of tubes TCT – it can cover several sizes of cables (e.g., 25-35-50mm2 or 150-185-240 mm2) and can be used for assembly of multi dimensional heat shrinkable cable kits.

ТСТ-А tubes (KBT) are supplied by 1 m. cutting-10 pieces in a pack. The range of represented sizes is most optimal size range - from 24/8 to 55/18mm.

Anti-tracking tubes ТСТ-А (KBT) are widely used not only in Russia, but also in the countries of the Customs Union, for assembling heat shrinkable cable kits.
