GEDORE Abisolier- und Crimpwerkzeuge

Wire stripping pliers differ primarily in the extent to which the tool determines the work process. Classic models are adjusted to the respective conductor. Automatic versions adjust themselves within their specified working range and are particularly suitable when working with frequently changing cross-sections.

The 8098-160 JC wire stripping pliers represent the classic principle with an adjustable opening width. The 8097 automatic wire stripping pliers, 0.2–6 mm², 200 mm, largely adjust themselves within their working range. The 8154 StrippMax-Pistol Professional wire stripping pliers complement the range for recurring stripping work.

Selection criteria:

• The type of conductor and cable construction determine the appropriate stripping principle.
• The cross-section must fall within the specified working range.
• A defined stripping length facilitates repeatable connection work.
• Automatic tools reduce the need for adjustments when working with different cables.
• After stripping, the conductor should be free of notches, crushing and damaged strands.

A short but crucial sequence of steps precedes a crimped connection.

1. Cutting the cable to length

   The cut should be as clean and perpendicular as possible. Heavily crushed or frayed conductor ends make the subsequent work steps more difficult.

    

2. Removing the insulation to the correct length

   The stripping length depends on the intended contact. Too little exposed conductor can result in an incomplete connection. Too much exposed conductor may remain visible outside the contact area.

    

3. Inspecting the conductor

   With fine-stranded conductors, particular attention should be paid to cut or missing strands. Notches should also be avoided in solid conductors.

    

4. Preparing the connection

   Only after inspection is the conductor inserted into the wire end ferrule, cable lug, connector or contact and positioned for the crimping process.

During crimping, the connection is created through a defined process of plastic deformation. The conductor and contact are pressed together to create a mechanically strong and electrically suitable connection. A prerequisite is a crimp profile that matches the respective contact.

Various solutions are available for wire end ferrules. The 8139-155 TC wire end ferrule crimping pliers with a special prism feature a fixed tool geometry. The 8141 precision crimping pliers for wire end ferrules are designed for repeatable crimping processes. Modular solutions such as the 8151-3 crimping die set enable the crimping range to be changed using suitable dies.

Important features of a properly coordinated crimping process:

• The conductor cross-section and contact size match.
• The crimp profile corresponds to the intended type of contact.
• The force is transferred evenly.
• After crimping, the contact is firmly seated on the conductor.
• Recurring connections can be reproduced consistently using the same tool configuration.

GEDORE also offers VDE versions for electrical applications, including the VDE 8098-160 VDE wire stripping pliers with dip insulation and the VDE 8098-160 H VDE wire stripping pliers with sleeve insulation.

The insulation does not change the basic function of the pliers. It adds the protective insulation required for the intended application. The applicable work instructions and safety requirements remain decisive.
