<p>A device and a method for shrinking heat recoverable sleeves for covering cable joints comprising a heating device the interior of which has a plurality of independently energisable heating elements and at least one sensor and a control circuit or control circuits which are connected to the heating elements and the at least one sensor. The control circuit is arranged to produce a uniform and then a non-uniform temperature profile within the heating device unless the initial temperature within the heating device is above a given temperature (e.g.) 30 °C, in which case the control circuit waits until the temperature within the heating device falls to below the given temperature before producing the temperature profiles, whereby sleeved cable joints of a uniform quality are produced by avoiding air entrapment within the sleeve during the shrinking process.</p> |
