Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the invention will be further described

[0025] Please refer to FIG. 1 , a schematic structural diagram of a direct loading composite insulator and a preparation method thereof of the present invention. As shown in Figure 1, a direct loading composite insulator includes a core 1 and an end attachment 12 connected to the end of the core 1, the core 1 is made of glass fiber bundles 11 bonded and wrapped by silicone rubber The outside of the connecting body between the core body 1 and the end attachment 12 is formed as a whole by wrapping silicon rubber. The connection between the core body 1 and the hanging ring 12 is realized by the way that the glass fiber bundle 11 in the core body 1 wraps around the hanging ring 12 . The sheath 3 and the shed 2 are of an integrated structure, which is made by silicone rubber injection process.

Abstract

The insulator includes core body, end accessory, jacket, and umbrella skirt. Using multithreaded silicon rubber bonds and packs bundles of glass fibers makes the core body. Using technique of injecting silicon rubber forms an integral of end accessory, jacket, and umbrella skirt. The preparation method includes steps: first, bonding silicon rubber on surface of glass fiber; next, using glass fiber bundle wraps and fixes up suspension loops on two ends, and forms the core body composed of multi stranded bundles of glass fibers wrapped by silicon rubber; then, using technique of injecting silicon rubber forms an integral of end accessory, jacket, and umbrella skirt. Advantages are: greatly enhanced bearing capacity of composite insulator; stable and reliable mechanical features, small dispersivity of tested values of mechanical load; better stability of connection between the core body and the suspension loops; and the core body will not be damaged by the said connection.

Description

technical field [0001] The patent of the invention belongs to the technical field of power transmission and transformation, and relates to a direct load-bearing composite insulator for insulation and mechanical fixation between the charged body, that is, the transmission wire, and the grounding body, that is, the pole tower, for overhead transmission lines with a rated voltage higher than 10kV and its preparation method. Background technique [0002] Due to the increasing capacity of power transmission and transformation, the voltage continues to rise. The requirements for the safety and reliability of overhead transmission lines are also getting higher and higher. The better the electrical insulation performance and the longer-term stable and reliable mechanical properties of insulators used for insulation and mechanical fixing between transmission wires and towers when used in high-voltage overhead transmission lines, the higher their use value. [0003] At present, amon...
