Science and Technology on behalf of the
Chinese name: insulating English Name: Insulator Definition 1: the potential of the conductor is mounted between the ground potential or the guide member, and able to withstand the mechanical stress voltage device. Science: power (a subject); transmission lines (two subjects) Definition 2: a period of about several hundreds of base pairs can interfere with the DNA sequence of a eukaryotic gene regulatory protein Jiyinshijia influence on the distance.May buffer isobutyl repression of chromatin, when it is in its regulatory regions flanking the gene, the gene can be expressed regardless of its normal position in the genome; and when located between the target gene promoter and enhancer, you can block the action of enhancers. Science: Biochemistry and Molecular Biology (a subject); gene expression and regulation (two subjects) Definition 3: the cis-acting elements.About hundreds of nucleotide pairs, usually located in the promoter or positive regulatory element between the negative one regulatory sequence regulatory element. Science: Genetics (a subject); Molecular genetics (two subjects)
Insulator is a special insulation controls, can play an important role in the overhead transmission lines.Insulator used for the early years of poles, and slowly developed in the high-pressure end of the wire connecting the tower were a lot of disk-shaped insulator, which is to increase the creepage distance, usually made of glass or ceramic, called Insulator.Insulator for overhead power transmission lines plays a fundamental role in two, i.e., support wires and back to prevent the current, these two actions must be guaranteed, Insulator should not lead to a variety of electrical and mechanical stress and environmental conditions of the electrical load and failure occurs, Insulator otherwise would not have a significant effect, it will damage the use and operation of the entire line of life.
