Description

Technical Field

[0001] This utility model relates to a high-strength waterproof tension insulator, belonging to the technical field of tension insulators. Background Technology

[0002] Tension insulators, also known as guy wire insulators, are important insulating devices used in power systems for guy wires on overhead lines. They isolate the guy wire from grounding bodies such as poles and towers, preventing electric shock accidents or line faults caused by accidental energization of the guy wire, and ensuring the safe operation of the power system. Currently, tension insulators typically have iron rings at both ends of the core column. The contact points between the iron rings and the core column are prone to water accumulation and corrosion. For example, a composite tension insulator with silicone rubber coating mentioned in authorization announcement number CN221379065U includes an insulator core column, with a first U-shaped iron ring and a second U-shaped iron ring fixedly installed at both ends of the insulator core column. The first U-shaped iron ring and the second U-shaped iron ring are arranged perpendicular to each other, and anti-rust components are provided on the outer rings of both the first U-shaped iron ring and the second U-shaped iron ring.

[0003] Existing technologies have the following problems:

[0004] Existing tension insulators protect the iron ring and core post by pressing down through rotating threads, which creates a threaded layer on the surface of the iron ring. This damages the integrity of the structure, reduces its ability to withstand mechanical stress, and thus reduces the overall strength of the tension insulator. Furthermore, it is difficult to conveniently reinforce the core post with fiberglass strips, which hinders its widespread use. Utility Model Content

[0012] Preferably, the bottom surfaces of the first sealing ring and the second sealing ring are both slidably connected to the insulating core, and the outer diameter of the first sealing ring is the same as that of the second sealing ring.

[0013] The beneficial effects of this utility model are:

[0030] Example 2

[0031] Please see Figure 3 The difference between this embodiment and Embodiment 1 is that:

[0032] An insertion block 10 is fixedly connected to the surface of the first bonding plate 5 near the second bonding plate 8.
