This document provides specifications for various hydraulic press heads and their accessories for crimping electrical connectors. It includes details on storage dimensions and weights for the press heads, their maximum crimping force and operating pressure, compatible die sizes and applications. Press heads can crimp connections up to 630 or 1200 square mm and are compatible with dies for tasks like cutting conductors or compressing connectors for low voltage, high voltage, overhead power lines and more. Optional adapters allow heads to use dies standardized to most 130 kN tools.
