Casing

Casing is an accessory used to protect optical cables, typically employed in high-voltage transmission lines. Its primary function is to protect the cable from mechanical damage and ensure the cable remains stable in the suspended state. Below is a detailed introduction to the hanging fixture sleeve:

Uniform stress distribution: The hanging fixture housing is designed to distribute stress evenly, preventing concentrated stress at the cable installation point, thereby protecting the cable from damage.

Excellent dynamic stress bearing capacity: The double-layer structure design enables the hanging fixture shell to effectively withstand unbalanced loads over long periods, providing greater protection for the cable.

Large contact area and flexible rubber clamp:The large contact area with the optical cable, combined with flexible rubber clamps, reduces wear and enhances the self-damping effect.

Corona discharge voltage reduction: The flat surface and smooth end shape design reduce corona discharge voltage and minimize power loss.

Aluminum alloy material: The use of aluminum alloy improves the mechanical properties and corrosion resistance of the suspension fixture shell, extending its service life.

Easy installation: The hanging fixture shell is designed for easy installation, requiring no professional tools, thus reducing construction difficulty and costs.

The suspension jig housing is widely used in high-voltage transmission lines, especially for ADSS/OPGW cable suspension and protection. It is suitable for various types of towers, including linear towers and tensile towers, to meet different spacing and stress requirements.

Correct selection of specifications: The appropriate hanging fixture shell should be chosen based on the cable's external diameter, breaking strength, allowable tension, and other technical parameters.

Installation position: The hanging fixture casing should be installed at stress concentration points on the cable, such as corners or terminals, to provide optimal protection.

Fastening strength: During installation, ensure that the fastening strength between the hanging fixture shell and the cable is appropriate. This will prevent cable damage or loosening caused by overly tight or loose fastening.

Regular inspection: Regular inspections of the suspension jig casing should be conducted to ensure it remains intact, with timely replacement of damaged or aging parts.
