Hardware in the transmission and transformation line is an indispensable part of the power line, mainly used to connect, fix, protect and support conductors, insulators and other equipment. According to the purpose and function, the transmission and transformation line hardware can be divided into the following categories, Now we hydget take you each of which contains a variety of specific types:
1. Wire clamp hardware
Wire clamps are mainly used to fix conductors or ground wires, and are divided into the following types:
Suspension wire clamps: used to hang the conductor or ground wire on the insulator string of the tower to bear the vertical load of the conductor.
Common types: aluminum alloy suspension wire clamps, pre-twisted suspension wire clamps.
Tension wire clamps: used to fix the conductor or ground wire on the tension insulator string of the tower to bear the tension of the conductor.
Common types: wedge-shaped tension wire clamps, bolt-type tension wire clamps, crimping-type tension wire clamps.
Splicing wire clamps: used to connect two sections of conductors or ground wires to ensure electrical and mechanical properties.
Common types: crimping-type splicing wire clamps, bolt-type splicing wire clamps.
Split conductor spacer: used to maintain the spacing between split conductors and prevent the conductors from colliding with each other due to wind vibration or electromagnetic force.
2. Connecting hardware
Connecting hardware is used to connect insulators, hardware and conductors, and mainly plays a mechanical connection role. Common types include:
U-shaped hanging ring: used to connect insulator strings and poles or other hardware.
Ball head hanging ring: used to connect the ball head part of the insulator string.
Joint plate: used to connect two sections of insulator strings or hardware.
Common types: parallel connecting plate, triple connecting plate, quadruple connecting plate.
Hanging plate: used to fix the insulator string on the pole tower.
Common types: single hanging plate, double hanging plate.
Turning hanging ring: used to change the direction or connection angle of the insulator string.
3. Protective hardware
Protective hardware is used to protect conductors, insulators and other equipment from damage caused by external forces or environmental factors. Common types include:
Anti-vibration hammer: used to reduce the vibration of the conductor caused by wind vibration and protect the conductor from fatigue damage.
Protective wire clamp: used to protect the conductor from wear at the hanging point.
Protective wire: used to protect the wire from mechanical damage in special parts (such as crossings).
Lightning protection hardware: used to protect the line from lightning damage, such as lightning arrester clamps.
4. Cable tie hardwareThe cable tie hardware is used to fix and adjust the cable of the pole tower to maintain the stability of the pole tower. Common types include:
Cable clamp: used to fix the cable to the pole tower.
Cable clamp: used to fix the end of the cable.
Turnbuckle: used to adjust the tightness of the cable.
SummaryThere are many types of hardware for transmission and transformation lines, and various types of hardware play different roles in transmission lines. Together, they constitute the mechanical support and electrical connection system of the transmission line to ensure the safe and stable operation of the line.
