A 4-wire T-shaped crossarm is a component commonly used in overhead power or communication lines. It usually has a T-shaped structure and is made of metal materials such as angle iron. Its main function is to support and fix four conductors. By fixing the 4-wire T-shaped crossarm on the pole or wall through bolts, it can bear the weight of the conductors and external forces, such as wind force and ice load, and maintain the insulation distance between the conductors to ensure the safe and stable operation of the line.
