Crimping Range (4-70mm²): This is the most important specification, indicating the cross-sectional area of the copper or aluminum cable lugs/terminals that the tool can effectively crimp. This range is common for various electrical installations, automotive applications, and panel wiring.
Hydraulic Mechanism: Instead of purely manual force, a small hydraulic pump within the tool amplifies the user’s effort to create a powerful crimping force. This makes it easier to achieve tight, consistent crimps on larger conductors, which would be difficult or impossible with manual crimpers.
Crimping Force (e.g. 45KN, 50KN, 60KN): This indicates the maximum force the tool can exert. Higher force generally means it can handle tougher materials or produce more robust crimps. For a 4-70mm² range, common forces are around 45KN to 60KN (Kilonewtons ...
