Stringing blocks are designed with versatility and adaptability in mind to handle diverse conductor types:

• Interchangeable Linings: Many high-quality stringing blocks offer interchangeable linings made from materials like high-molecular weight polyethylene (HMWPE), polyurethane, or aluminum alloy. This allows for optimal friction reduction and protection based on the conductor's outer material and sensitivity (e.g., specific linings for ACSR, AAAC, or delicate OPGW).

• Variable Groove Sizes: Blocks come with a range of groove sizes to perfectly cradle conductors of different diameters, preventing flattening or deformation.

• Multi-Groove / Bundle Blocks: For bundled conductors (e.g., 2, 3, 4, or more conductors per phase), specialized multi-groove stringing blocks are used. These blocks feature separate, precisely spaced grooves for each sub-conductor, ensuring they maintain their relative positions and share tension evenly during stringing, preventing clashing or damage.

• Large Sheave Diameters: For very large or sensitive conductors (like UHV lines or OPGW), stringing blocks with significantly larger sheave (wheel) diameters are employed. A larger diameter reduces the bending radius of the conductor as it passes over the sheave, minimizing stress and potential damage.

• Universal Mounting Options: Different frame designs and mounting mechanisms (e.g., universal hangers, swivel hooks, fixed-point attachments) allow blocks to be securely and correctly positioned on various tower types and structures, optimizing the conductor's path.
