Hook M20/200 mm SOT21

Hook for mounting overhead ground wires

This hook, made of steel and protected with hot-dip galvanizing, is a key element in the construction and maintenance of power lines. SOT21 is used to securely mount suspension clamps in both main lines and connections. Its solid construction and high strength guarantee reliable operation even in harsh weather conditions and mechanical loads.

Design and application

The hook is designed for easy installation and long-term operation. A thread length of 120 mm and an overall length of 319 mm ensure a stable connection to the pole structure. The inner diameter of the eye (38 mm) allows cooperation with various types of suspension clamps. A pin diameter of 20 mm provides adequate tensile strength. Hot-dip galvanizing is not only corrosion protection but also increases the element's lifespan, which translates to less frequent replacements and lower installation maintenance costs.

Strength and compliance with standards

The SOT21 hook is characterized by high strength parameters – test load Fx is 24.1 kN, and Fy is 9.4 kN. It meets the requirements of SFS 2452 and SFS 2451 standards, which confirms its quality and safety of use. This guarantees that the element will perform its task even in demanding applications. Steel construction provides resistance to mechanical damage, and hot-dip galvanizing protects against the effects of atmospheric factors – moisture, UV radiation, and road salt.
