Among them, the frame body 11 forms the outer frame of the entire tower head 100, and is generally made of metal materials to ensure strength, and can also be made of composite insulating materials to prevent flashover between the mounted transmission line and the frame body 11 . Frame body 11 shape can be heart shape, apple type, racket shape or animal modeling etc. have aesthetic feeling shape; Can also be designed according to its environment, for example in Olympic village, frame body can be designed as racket shape; For regions where a particular animal is known, the frame can be designed in the shape of that animal.
