Electrical stress control
Whether the cable accessories can operate reliably depends on whether the electric field stress at the end of the cable cutout can be properly evacuated. The material used in the heat shrinkage stress control tube has a volume resistivity and a dielectric constant that matches the electric field of the cable at the connection. The operation forms an impedance at the end of the cable shield to act as an electrical stress evacuation to ensure that the heat- Operational reliability and extended service life.Technical Data
