Pinza crimpatrice Wiha 45959 per capicorda non isolati, versione chiusa

The Wiha 45959 crimping tool for non-insulated cable lugs is a hand tool engineered to create durable mechanical and electrical connections in copper cable terminations. Its closed design provides even pressure distribution across the contact area, reducing the risk of incomplete crimps and improving consistency from one termination to the next. The tool is intended for use on non-insulated lugs and terminals and is suitable for electricians and technicians working on electrical installations, panel wiring and equipment maintenance.

Advantages

The closed-jaw construction ensures uniform compression over the lug barrel, which helps produce reliable, gas-tight crimps with minimal deformation of conductor strands. The tool’s ergonomic handles support controlled force application and reduce fatigue during repetitive work. Constructed from hardened materials, it maintains crimping geometry over prolonged use, supporting repeatable performance and stable electrical contact.

Key specifications

How to use

Select the appropriate lug size for the conductor and insert the stripped cable into the lug barrel. Position the lug fully within the closed crimping cavity and align the conductor so it sits straight in the barrel. Squeeze the handles steadily until the crimping dies complete the compression cycle and the lug is firmly deformed around the conductor. Inspect the finished crimp visually and, where applicable, perform a pull test or continuity check to verify mechanical and electrical integrity.

Recommendations

Use the tool with properly stripped and prepared copper conductors and the correct size of non-insulated lug to ensure reliable connections. Avoid using the tool on insulated terminals or on materials other than intended. Periodically inspect the crimping surfaces for wear or damage, and maintain clean contact faces to preserve consistent crimp quality.
