The main iron components of the line include angle steel support iron, grounding pipe, ground anchor rod, cable protection pipe, pull rod, five hole connecting plate, flat connecting plate, double-sided pole top iron for power iron accessories, triangular bracket for power iron accessories, U-shaped clamp for power iron accessories, lightning rod, tension arm, etc. Angle steel support iron is mainly used for making frame structures, such as high-voltage transmission towers, frames on both sides of steel bridge main beams, columns and arms of tower cranes on construction sites, columns and beams in workshops, and small places such as placing flower pot shaped shelves on the roadside during festivals, and hanging air conditioning and solar energy shelves under windows. The grounding pipe is necessary to ensure the normal operation of the power system. For example, in a system where the neutral point is directly grounded, the neutral point of a transformer is grounded to stabilize the potential of the power grid to the ground, thereby reducing the insulation to the ground. Cable protection pipes are mainly installed at the intersection of communication cables and power lines to prevent short circuit accidents caused by power line breakage, which can cause electrification of communication cables and steel wire ropes. They are used to protect cables, switches, core boards, and even the entire machine from being burned out, and also have a certain isolation effect on the magnetic field interference of power lines. The triangular bracket for power iron accessories comes in two sizes: long and short, with high strength, rated load of 120kg, light weight, detachable storage, small size, and convenient use and transportation. It is a supporting product for telescopic bridge slabs. In the power system, every circuit iron component may seem small, but it plays an irreplaceable role. So when purchasing, it is necessary to purchase brands with guaranteed quality in order to ensure the normal operation of the power system
