  "Screws" are just a basic term for  fasteners . They are day-to-day words. They include bolts, screws, nuts. As long as there are threaded fasteners, screws, studs, bolts, and also screws all have one thing in common, that is, they have strings. Along with the thread, what are the various other differences? In the following, I will certainly introduce the distinction between bolts, screws, and studs. How to identify the screw fasteners?   What is the distinction between screws, studs, and also bolts?   1. Screw: It is likewise a sort of fastener containing two parts, head as well as screw. It can be separated right into three categories according to the purpose: device screw established screw and also special-purpose screw. The screw is mainly made use of for a firmly threaded part as well as a limited link in between a get rid of a via opening and does not require a nut fit( this kind of connection is called a screw link as well as is likewise a detachable connect...

  A power divider is a device that divides the energy of an input signal into two or multiple outputs of equal or unequal energy, and can also combine the energy of multiple signals into one output in reverse, which can also be called a combination. router. A certain degree of isolation should be guaranteed between the output ports of a power divider. Power divider   is also called overcurrent divider. It is divided into active and passive. It can evenly distribute one signal into several outputs. Generally, each branch has a few dB attenuation. The signal frequency is different, and the attenuation of the divider is also different. Different, in order to compensate for the attenuation, a passive power divider is made after adding an amplifier. The technical indicators of the power divider include frequency range, withstand power, distribution loss from main circuit to branch, insertion loss between input and output, isolation between branch ports, voltage standing wave ratio ...

  Solid State High Frequency Welder  can not only heat the workpiece as a whole, but also target the local heating of the workpiece; it can realize the deep penetrating heat of the workpiece, and also focus on the heating of its surface and surface layer only; it can not only heat the metal material directly, but also heat the non-metal material indirectly. And so on. High-frequency welding machine and induction heating technology currently has the highest efficiency and fastest speed for heating metal materials, and low consumption and environmental protection. It has been widely used in all walks of life for thermal processing of metal materials, heat treatment, thermal assembly and welding, melting and other processes. It is therefore, induction heating technology has been more and more widely used in all walks of life. Solid State High Frequency Welder Induction current is used to make the workpiece locally heated surface heat treatment process. This heat treatment process...

Obviously, if the transmission line is not properly insulated from the support of the tower or pole, then the current will flow in the direction of the ground through the tower and thus become dangerous. Of course, the transmission line is always supported by   insulators   placed on the poles. Insulators used for towers must have high mechanical strength, high resistance, and high relative permittivity, etc.   Types of insulators These are divided into different types according to their ratings, which include the following. These are used in transmission and distribution systems, where each insulator consists of several insulating discs. If one disc uses 11kv voltage, the remaining discs use 66kv voltage.   AC Standard Glass Insulator Insulators are divided into five different main types.   Post Insulator Shackle Insulator Pin insulators Strain insulators Suspension insulators   1. Post insulators Post insulators are commonly used in substations or power g...
