Sheath

The outer insulating sheath of a cable is crucial for its performance and reliability in various applications. This sheath surrounds one or more shielded or unshielded conductors and provides protection against external influences as well as insulation between the conductors and their environment.

One of the most important requirements for the sheath is temperature resistance. Depending on the area of application, a cable may be exposed to extreme temperatures, whether in industrial environments, outdoors or near heat sources. A high-quality sheath must be able to withstand these temperatures without compromising its structural integrity or insulating properties.

Abrasion resistance is another important property. Cables can be exposed to various mechanical loads during installation, handling or operation, which can lead to abrasion and damage. A robust sheath protects the cores from such damage and ensures the long-term reliability of the cable.

Compressive strength is particularly important in environments where the cables are exposed to heavy mechanical loads, be it from heavy equipment, pressure from surrounding materials or other external influences. A jacket with high compressive strength ensures that the cable keeps its structure intact and protects the cores from damage caused by pressure.

To summarise, the outer insulating sheath of a cable must be robust and resistant to meet the requirements of various applications. It must withstand temperatures, be abrasion resistant and have sufficient compressive strength to protect the cores it contains and ensure reliable performance.
