Line Iron Parts refer to various metal components and accessories used for overhead power lines. Their main function is to support, fix, connect and protect power lines to ensure the safe and stable operation of the power system. They must be produced by professional manufacturing companies, such as Handan Jinmai Fastener Manufacturing Co., Ltd. The production and testing usually follow specific industry standards.

Here are some common accessories:
Crossarms: used on poles or transmission towers to support insulators and wires.
Insulators: used to support wires and provide electrical insulation to prevent current leakage.
Protective Covers: used to protect insulators and other components from environmental influences.
Suspension fittings (: used to fix the wires on the crossarms, allowing the wires to have a certain suspension.
Tension fittings)**: used to withstand the tension of the wires, commonly found at the terminals or corners of the line.
Connecting fittings: used to connect two sections of wires or wires and equipment.
Connection fittings*: used for the connection of wires to extend the length of the wires.
Protective fittings: such as anti-vibration hammers, damping wires, etc., used to reduce the vibration and swing of wires.
Fastening hardware: such as bolts, nuts, washers, etc., used to fix and fasten other hardware.
Wire fittings: used to fix the wires and maintain the tension and position of the wires.
Lightning protection hardware: used to protect power lines from lightning strikes.
Cable hardware: used to fix and connect cable lines.
Pole cap: installed on the top of the pole to fix the crossarm.
U-bolt: used to fix the crossarm or other structural components.
U-pin: used to connect and fix power hardware.
Ground anchor: used to fix the wire to ensure the stability of the line.
Vibration isolator: used to reduce the vibration of the wire and extend the service life of the wire and hardware.

Before installation, it is necessary to plan according to the design drawings and specifications to determine the type, size and installation location of each iron fitting. For transmission towers or poles, basic construction needs to be carried out first to ensure that they can support the weight and tension of the entire power line. Crossarms are usually installed on poles or transmission towers with bolts, pins or other fasteners. It is necessary to ensure that the crossarms are level and firmly fixed. Insulators need to be installed on the crossarms at specified intervals to support the conductors and provide the necessary insulation. The conductors are fixed to the insulators by conductor clamps or tension clamps. The conductors need to be erected according to the designed tension. The grounding device needs to be installed in the appropriate position to ensure safe conduction to the ground in the event of lightning strikes or overvoltage. All fasteners, including bolts, nuts and washers, need to be tightened according to the specified torque value. Anti-vibration hammers or other anti-vibration devices are installed on the conductors to reduce wind vibration and vibration of the conductors. After installation, the power line needs to be tested, including insulation testing and load testing, to ensure that all components are working properly.

These Line Iron Parts are usually made of steel and are galvanized or otherwise treated with anti-corrosion to improve durability. They play a vital role in the construction, maintenance and upgrading of power lines, and their quality and performance directly affect the reliability and safety of the power system.
