What Is A Sheathed Cable Used For?

What is a sheathed cable used for?

The cable sheath is the outermost layer of the cable, and its main function is to protect the cable, such as PVC flexible cable polyvinyl chloride sheathed power cable. The sheath of this type of cable is made of polyvinyl chloride, which can protect the cable core. , to protect the inner sheath from mechanical equipment damage and chemical corrosion, not to touch the water vapor to return moisture, to avoid touching the electric conductor and electric shock accidents, etc., which can improve the impact toughness and increase the service life.

1. What is the function of wire and cable sheathing?

The tear resistance and high temperature resistance of cables in different places are different. High-quality cable jackets must have excellent physical and physical properties, such as compressive strength, bending resistance, vibration resistance, torsion resistance, etc., suitable for A variety of different application environments; no matter how harsh the environment, the cable can operate normally under the maintenance of the cable jacket.

Second, the importance of wire and cable!

In fact, the cable sheath is a safety precaution for the inner sheath, so that the cable sheath is not easy to touch with water, gas or other objects, avoids the moisture return of the insulation layer and the cable sheath is not subject to unsafe behavior. If the cable sheath is damaged and the inner conductor is exposed, not only the cable is susceptible to air oxidation, but also there is a risk of electric shock if the copper conductor is accidentally touched.

Third, the type and function of the outer sheath of the wire and cable!

1. The inner lining is located between the armored layer and the inner protective layer. Its function is to prevent the inner protective layer from being corroded and to prevent the inner protective layer from being damaged by the armored layer when the cable is bent.

2. The armor layer is outside the inner lining layer, and its function is to reduce the influence of mechanical force on the cable, so that the mechanical force acting on the cable is borne by the armor layer.

3. The outer quilt is outside the armored layer, and its function is to prevent the armored layer from being corroded. Therefore, the function of the outer sheath of the cable is to protect the inner sheath from external influences and mechanical damage.
