Power cable lug for 25mm cable with 10mm hole – code: 14.035.26 – Osculati

Osculati power terminals for 25 mm² cable with 10 mm hole (code 14.035.26)

I power terminals are essential components for making neat and reliable electrical connections in systems where cables of significant section are used. This model Osculati, Osculati code 14.035.26, is designed for use with 25 mm² cable and features a 10 mm hole, useful for fastening on bolts or terminal blocks with consistent sizing.

The construction is in high conductivity tinned copper, a typical choice for power applications and contexts where good electrical contact quality and a finish suitable for technical environments, including onboard ones, are sought.

Features and construction details

Material

The terminal is made of tinned copper and described as having high conductivity. Tinning is a commonly adopted finish to protect the copper surface and maintain a clean contact over time, especially in installations subject to periodic maintenance.

Dimensions and configuration (variant selection)

This variant is identified by the following parameters:

• Cable section: 25 mm²
• Hole: 10 mm
• D1: 9.5 mm
• D2: 7.1 mm
• D3: 16 mm
• D4: 10.5 mm
• L: 40 mm

Note: The dimensions are useful for checking space requirements and mechanical compatibility with adjacent terminals, busbars, clamps, and fastening points, especially when space is limited.

Product identification

• Manufacturer/Supplier: Osculati S.r.l.
• Supplier product code: 14.035.26

Typical applications (nautical and plant engineering)

A power terminal lug for 25 mm² cable is normally used in connections where a ring terminal is desired for tightening with a screw or bolt. In nautical and onboard plant contexts, it can be used, for example, for:

• connections on and for managing the main connections of the electrical system. In a nautical context, it can be used in many operational situations, for example on pleasure boats or technical installations where an orderly and easily recognizable connection is required. and battery disconnect switches (depending on the available bolts);
• connections on distribution bars and junction points;
• wiring of power lines where a mechanically stable terminal is required;
• interventions of maintenance or terminal replacement on existing cables, when the cross-section and hole must remain consistent with the system.

The choice of hole (10 mm) is particularly important: it allows alignment with the connection point bolts without improper adaptations.

Advantages during installation

Neat and inspectable connection

The ring terminal allows stable fastening and a cleaner arrangement of cables compared to temporary solutions. In a technical system, the ability to inspect and quickly restore connections is a practical advantage.

Choice of tinned copper

The tinned copper is a common solution for terminals intended for contexts where a protected surface suitable for power electrical connections is desired. In particular, tinning helps maintain good contact surface quality over time, if the installation is done correctly and with proper maintenance.

Consistency between cable cross-section and terminal

Using a terminal lug sized for 25 mm² allows working with geometry designed for that cross-section, reducing compromises during crimping and facilitating a more straightforward assembly.

Usage and operational notes

Crimping and tooling

To properly fix the terminal lug to the cable, crimping must be performed with a suitable tool. For this product family, a tool for fixing terminals on electrical cables with code 14.035.30.

In general, it is good practice:

• prepare the cable with adequate stripping (without damaging the strands);
• fully insert the conductor into the terminal;
• perform crimping with compatible and well-maintained equipment;
• check the mechanical tightening and absence of play before commissioning.

Checks before purchase

To choose the correct variant, always check:

• cable cross-section (here: 25 mm²);
• hole diameter required by the fixing point (here: 10 mm);
• space requirements available (dimensions D1/D2/D3/D4 and L) if installation takes place in tight spaces or with multiple terminals side by side.

Note on installation and safety

In power electrical systems, a properly executed connection is essential for smooth operation and to simplify maintenance. If you do not have the necessary equipment or experience, it is advisable to entrust the installation to qualified personnel.
