How is pulling tension controlled to meet HV cable standards?
2025-08-16Controlling pulling tension is one of the most critical aspects of high-voltage (HV) cable installation. Exceeding the manufacturer's specified maximum pulling tension can stretch the conductors and damage the sensitive insulation, leading to premature cable failure. To meet these stringent standards, installers must use specialized equipment.
Our hydraulic cable pullers are designed with an integrated dynamometer and a tension monitoring system. This allows the operator to set a maximum pulling limit. If the tension approaches this limit, the machine automatically slows down or stops, preventing damage. This technology is essential for demonstrating compliance with HV cable installation standards and for protecting the valuable asset being installed.
