Insulator is a special insulation control, which plays an important role in overhead transmission lines. Mainly used for the connection of wires and cables. For example, a lot of disk-shaped insulators are hung on one end of the high-voltage wire connection tower, which is to increase the creepage distance, usually made of glass or ceramic, which is the insulator.
Insulators are a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for telegraph poles, and slowly developed a lot of disk-shaped insulators hung on one end of the high-voltage wire connection tower. It is used to increase the creepage distance. It is usually made of glass or ceramic and is called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two roles must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulators will not have a significant effect and will damage the use and operating life of the entire line.
Overview Insulators are about a few hundred nucleotide pairs long, and are a regulatory sequence usually located between a promoter and a positive regulatory element (enhancer) or a negative regulatory factor (heterochromatin). The insulator itself has neither a positive nor a negative effect on gene expression, but its function is to prevent other regulatory elements from having any effect on the activation or inactivation effects of genes.
Tempered glass insulators for structural power transmission and distribution lines are generally composed of iron caps, toughened glass or ceramics and steel feet, and they are combined with cement glue.
Function There are many disc-shaped insulators hung on one end of the high-voltage wire connection tower, which is to increase the creepage distance, usually made of glass or ceramics, called insulators.
