Extensive research in developing heat shrink technology and decades of experience on field, Raychem has a complete system of cable accessories up to 245 kV. Long term performance of Raychem heat-shrinkable materials has been demonstrated by the well-proven Power Accessory System. Millions of installations in some of the most severe service conditions have confirmed the reliability of the heat-shrink technique under high electrical, thermal and environmental stresses. Cable accessories of all voltages include a specially designed stress control mechanism which controls the electrical stress distribution for an enhanced product performance. In terminations, the insulating tubing ensures non-tracking and erosion resistant surface at extreme operating conditions.
