Terminations with built-in stress control for jacketed concentric neutral cables. HVT-Z medium voltage termination system features a co-extruded one-piece termination . Unlike the HVT product line, which includes a non-tracking tube and a separate stress control tube, the HVT-Z termination consists of the same proven non-tracking tube together with a co-extruded, built-in stress control grading layer . This stress control layer is based on ceramic semiconductor technology (ZnO) and provides superior discharge and impulse performance . When the tubing is shrunk down, the coating softens and sticks to irregular surfaces, providing moisture seals as well as electrical stress control . The termination design provides a superior product with a shorter overall length and fewer rain sheds than the HVT product line. Fully qualified Class 1 termination per IEEE-48 for a long, trouble free service life.
