Wire end sleeves

What are wire end ferrules

Ferrules are terminals used to connect or insulate electrical wires or cables. They are an important part of electrical systems and have been used for many decades. They have evolved and improved over time to meet the requirements of modern electrical systems.

What are wire end ferrules used for?

Wire end ferrules are used to connect electrical wires or cables securely and permanently while protecting them from corrosion or damage. They serve as an electrical connection point and facilitate the installation and repair of electrical systems. They are also used for the clean and secure termination of stripped stranded wires. With the help of wire-end ferrules, the stranded wires are reliably insulated when jammed. This prevents wires from slipping out of the terminal and causing short circuits.

What are twin wire-end ferrules?

Twin ferrules are electrical connectors used to secure and terminate the ends of two electrical cables.

Insulated and non-insulated ferrules

Insulated ferrules are covered with insulation to provide electrical isolation between conductors. Non-insulated ferrules are not jacketed and allow an electrical connection between the conductors.

Which ferrule for which cable?

The choice of the right ferrule depends on various factors, such as the diameter of the cable or wire, the voltage, current and ambient temperature in which the electrical system is operated.

Ferrules come in different sizes depending on the diameter of the wire or cable to be connected. There are standard sizes such as 0.5 mm², 0.75 mm², 1.5 mm², 2.5 mm² etc.

In addition, there are special sizes for certain applications, for example in industry.

They have different crimping levels depending on the diameter of the wire or cable to be connected. The crimping levels are usually marked with a number, e.g., crimping level 1 for small wires or crimping level 4 for larger wires. The crimping level determines how hard the wire or cable must be pressed into the sleeve to make a secure and permanent connection.

Common identification colours according to DIN

grey (length 8 mm, nominal cross-section 2 x 0.75 mm²) red (length 8 mm, nominal cross-section 2 x 1.0 mm²) black (length 8 mm, nominal cross-section 2 x 1.5 mm2) blue (length 8 mm, nominal cross-section 2 x 2.5 mm²)

What does it mean to crimp wire-end ferrules?

"Crimping ferrules" means to attach a ferrule to a wire or cable. This is done by inserting the cable into the sleeve and then compressing it with a crimping tool. This compression holds the cable securely and tightly in the sleeve and creates a permanent electrical connection. Crimping is an important technique in the installation of electrical systems to ensure safe and reliable connections.
