Overhead Line Fittings refer to the various hardware components used to support and connect the conductors (power lines) in an overhead electrical power transmission or distribution system.

Some common types of overhead line fittings include: Steel Parallel Groove Clamp, Alumium PG Clamp, Damper , Stay Rod, Strain Clamp, Spindle/Insulator Pin, Electrical Cross Arm, Socket Clevis , Insulated Wedge Clamp, D-Bracket , Eye Bolt , Hook , Shackle , Turnbuckle and other Overhead Line Fittings . 

These fittings are designed to withstand the mechanical and environmental stresses associated with overhead power lines, such as wind, ice, and conductor tension. The selection and installation of these components are crucial for the reliability and safety of the power transmission and distribution system.

An electrical cross arm, also known as a crossarm or power pole cross arms, utility pole cross arms, telephone pole cross arms, light pole cross arms or crossarms for short.

A cross arm is provided, for use in a support structure for conductors within an electrical grid，made of hot deep galvanized steel
