A heat recoverable conductive polymeric tubular article shrinks radially when electrical current is passed therethrough. It is powered by elongate electrodes extending along the article along part of the length only of the article, thereby defining an inwardly directed electrode end material of the article preferably has specific electrical properties to compensate for the increased current density that would otherwise exist at the inwardly directed electrode end, and which could lead to burning or hot spot formation. |
