The principle and structure of insulators are mainly reflected in their design to withstand voltage and mechanical stress, while increasing creepage distance and preventing flashover phenomena through specific structures.
Insulators are a special type of insulation control mainly used between conductors of different potentials or between conductors and grounding components to withstand voltage and mechanical stress. The basic principle is to increase the distance between the conductor and the ground to prevent current from directly returning to the ground, thereby protecting the safe operation of the circuit. The structure of insulators usually consists of two parts: insulation components and connecting fittings. Insulation components are the key part to ensure electrical insulation strength, while connecting fittings are used to fix insulators.
There are various shapes and types of insulators, including suspension insulators, post insulators, etc. They differ in structure and material, but all aim to achieve the same function: supporting and fixing wires while providing good insulation effect. For example, suspension insulators are mainly used for suspension parts such as anchor points and horizontal tie rods, while post insulators are used to support and fix wires.
In order to further prevent flashover, the design of insulators usually adopts an umbrella structure, which can reduce or block electric field lines, thereby reducing the possibility of flashover. In addition, on rainy days, flat discs can accumulate water, causing rainwater to flow towards the conductors below, increasing the risk of flashover. The umbrella shaped design can effectively avoid this problem, preventing rainwater from accumulating on the disc and further suppressing flashover phenomena.
