The 2/1 heat-shrink tubes are used for cable insulation up to 600 volts mostly in indoor applications.
They have excellent mechanical resistance and work ideally at temperatures from -75° to +125° degrees Celsius.
A 2/1 heat-shrink tube shrinks to half of its original diameter e.g. 6/3mm.
Characteristics:
✓ Operating temperature -75° to 125 °C
✓ Material: Polyolefin
✓ Resistance to electricity: 600 volts
