Crossarm pins are components of cross arms in transmission line systems.
The structure that holds and supports the overhead power lines, is called crossarms. Crossarm pins are used to hold crossarms together while preventing them from moving.
Crossarm pins are mainly used in transmission lines. It is used to connect crossarms, thereby joining the crossarms. By joining crossarms together, they are made stronger and more resistant to vibration.
They join two crossarms or a cross arm with an insulator mounted on it. It is also put into one crossarm for joining cross arms together.
The cross arm pins have three parts – the crossarm pin base, a crossarm pin body, and the crossarm pinhead. The cross-arm pin base is fitted in an opening of a cross arm.
An electrical cross arm is a strong and efficient pole hardware fittings that are used for supporting conductors in a power transmission line.
It is made up of steel due to its tensile strength & hot deep galvanized, which prevents rust, corrosion, and abrasion.
Steel is the right choice of material for the electrical cross arm due to its tensile strength. It can sustain the mechanical forces which may threaten its stability.
The electrical cross arm comes in five different configurations. These are the Power pole cross arm, Line-cross arms, Telephone pole cross arms, and Side arms. Each configuration is specifically designed to work well in its application
The hot line clamp is a metal structure that insulates current from high voltage transmission lines to the transformer. The aluminium body works either as a permanent or temporary fixture to connect conductors by using the keeper and eyebolt to secure and maintain a constant pressure as a reliable fixture to attach to hotlines.
The hot line clamp tap is specially designed for distribution tap connections and provides good corrosion resistance.

A lashing wire clamp is also called a cable lashing clamp, there are two types；D lashing wire clamp and E lashing wire clamp. The lashing wire clamp is used in building, mostly aerial construction, to secure lashing wire which is terminating or to hold the ground wire to a separate strand. This is an important safety feature when used in construction. The lashing wire clamp is made from stainless steel and is composed of a stud, two washers, and two bug nuts.
The strength of the lashing wire clamp jaws is more than 50,000 PSI. This makes the safety features of the product even better, as you can be sure the clamp jaws will not come undone when securing the lashing wire. This also minimizes damage to the cables.
Lashing clamps ensure bug nuts are tightened and the lashing wire itself is terminated properly. Terminating lashing wires stops them from breaking, which would result in poor connection, injury, or damage to the entire span of the lashing wire.
