Product Materials

● Main Material: High-quality carbon structural steel (Q235, Q355) and alloy structural steel, featuring high mechanical strength and excellent tensile and shear resistance, capable of withstanding heavy loads;
● Fasteners: Hot-dip galvanized carbon steel or stainless steel (304/316), providing corrosion resistance and preventing loosening to ensure secure connections and suitability for outdoor environments;
● Surface Treatment: Hot-dip galvanizing, Dacromet, and electrostatic spraying (optional). Hot-dip galvanizing is the standard option, featuring a uniform coating with outstanding corrosion and UV resistance, effectively extending service life;
● Cup Liner: Soft metal liner (optional), which reduces friction between the insulator ball and the cup, protecting the insulator and preventing wear.

FAQ

Q: What are W Socket clevis Eyes primarily used for?

A: They are primarily used in overhead transmission and distribution lines to connect insulator strings to suspension clamps and tension clamps, or to connect insulator strings to tower crossarms, serving to transfer loads and provide directional connections.

Q: What are the rated load specifications for W Socket clevis Eyes?

A: Standard rated loads range from 10 to 120 kN, covering the full series from W-7 to W-120. Special loads (＞120 kN) can be customized upon request.

Q: What are the standard installation steps for a W-type Socket Clevis Eye?

A: ① Precisely insert the insulator's spherical head into the socket of the bowl-head hanger and secure it with the locking pin; ② Connect the other end of the hanger to fittings such as a U-shaped hanger or a suspension clamp, and insert the bolt; ③ Tighten the bolt to the specified torque to ensure a secure connection; ④ Check that the hanger rotates smoothly without any binding.

Q: What are the installation requirements for the locking pin when installing a W-typeSocket Clevis Eye?

A: The locking pin must be fully inserted into the groove of the cap socket to ensure a secure fit with no looseness. When installing a single string of insulators, the spring pin must be inserted from the power supply side toward the power receiving side. When installing a double string of insulators, the spring pin must be inserted from the outer side of the double string toward the inner side. Omission or incorrect installation is strictly prohibited.
