The 2/1 heat-shrink tubes are used for cable insulation up to 600 volts mostly in indoor applications and cables color marking when is required for identification purposes in electrical systems.
They have excellent mechanical resistance and work ideally at temperatures from -75° to +125° degrees Celsius.
A 1/2 heat-shrink tube shrinks to half of its original diameter e.g. 6/3mm.
