Parallel type high-strength insulation device

A parallel type high-strength insulation device is a reliable operation device used in the field of optimizing a high-voltage power distribution network. The device is an innovative parallel type high-strength insulation device researched and developed in a new generation, and is mainly formed by fixedly connecting a steel parallel device, two porcelain insulators and a stamping fitting in an up-and-down gas welding manner. The periphery of the porcelain insulator is composed of open disc-diameter porcelain umbrella skirts which are alternated in size so as to play a role in preventing rainstorm and ice ridge bridge flashover. A double-row fixed parallel combined insulation device is adopted to replace a common suspension-rod-shaped porcelain insulator in the prior art, the breakdown phenomenon does not exist after the insulator is struck by lightning, and the insulator has the advantages of 10-time tensile strength, high strength, difficulty in brittle fracture, smooth surface, difficulty in dirt accumulatio
