Adhesive lined tubes TTK 2:1 with shrink ratio 2:1 are designed for insulation of electrical connections. The characteristic feature of the tubes is a smooth leveled thickness of the walls and adhesive glue, lined along the whole inner surface if the tube using the method of co-extrusion. The glue ensure safe connection and liquid tight connection for voltage up to 1000 V and also ensure mechanical strength after shrinkage.
Melting during heating, the glue fills all the spaces inside the tube. Adhesive qualities of the glue start to work only after shrinkage.
The tubes are highly resistant to UV-weather, humidity; they can be installed in earth or concrete. Comfortable in installation due to low shrinking temperature (115°С), high elasticity and thin walls. Supplied in a pack of 10 pcs cut by 1 meter each. Most popular sizes: from 4.8/2.4 up to 50/25.
