Power transformer
Transformer is a kind of common electrical equipment, widely used in power system and electronic circuit. It is a static electrical equipment, using the principle of electromagnetic induction to convert a voltage, current alternating electric energy into another voltage, current electric energy at the same frequency. In other words, the transformer is to realize the conversion of electrical energy between different levels.

High voltage component
High voltage components Insulator arrester cable Functions of high voltage components Insulators are used to support and secure the bus and the live conductor, and to provide sufficient insulation between the live conductors or between the conductor and the earth. Insulators should have sufficient electrical insulation strength and moisture resistance. PM low pin insulator PT high pin insulator post type insulator UT construction, clamp the steel strand into the slot. By using wedge splitting force, the strand is locked inside the online clip to achieve the purpose of tightening the cable. Generally used to pull the lower end of the wire tower type wire is a kind of straightened after proposed with iron wire cutting a certain size tie wire a screw, sometimes many people are used to..

Wire and cable
A cable is a wire made of one or more mutually insulated conductors and an outer insulating layer that transmits power or information from one place to another. Definition 2: A cord-like cable usually consisting of several or groups of conductors (each group of at least two) twisted together, each group of conductors insulated from each other and often twisted around a center, with a highly insulated covering covering the entire outer surface. The cable has the characteristics of internal electrification and external insulation.
