What is rectifier module? A  rectifier module  is an electronic device that converts alternating current (AC), which periodically changes direction, into direct current (DC), which flows in only one direction. There are several types of rectifiers, including half-wave rectifiers, full-wave rectifiers, and bridge rectifiers. Half-wave rectifiers only allow one half of the AC waveform to pass through, while full-wave rectifiers allow both halves of the AC waveform to pass through, but in opposite directions. Bridge rectifiers consist of four diodes arranged in a bridge configuration, which allows them to rectify AC voltage from either direction. Rectifiers are used in a variety of applications, including power supplies for electronic devices, battery chargers, and DC motor drives. They are also used in power transmission and distribution systems to convert high-voltage AC power into lower-voltage DC power for use in homes and businesses. Application of rectifier module Rect...

TFT type display is currently the better LCD color display,   TFT type display   has many advantages: high response, high brightness, high contrast ratio, etc. TFT display is closest to CRT display. TFT screen is also often found on the screen of major cell phones, there are 65536 colors, 160,000 colors, 16 million colors, it is also very good display. TFT means that the LCD on the Each LCD pixel is driven by a thin-film transistor integrated behind it. This allows for high speed, high brightness, and high contrast display screen information. TFT-LCD (thin film transistor liquid crystal display) is one of most liquid crystal displays. Liquid crystal display (LCD) . the structure of LCD is placed in the middle of two parallel glass liquid crystal box, the substrate glass is set on the TFT (thin film transistor), the color filter substrate glass is set in, to the TFT signal, the voltage changes to control the direction of rotation of the liquid crystal molecules, so as to a...

  Features of Ni-Cd batteries Nickel cadmium (Ni-Cd or “nicad”) batteries were invented way back in 1899 by a Swede named Waldemar Jungner. At that time, porous electrodes housed nickel, which was crafted into pockets for a nickel cadmium mixture to sit in and conduct electricity through.  After decades of research and experimentation, smart people found out that the more surface area inside a battery, the better for stronger electric currents.  Therefore,  Ni-Cd batteries  now resemble a “jelly-roll” inside, with porous anode and cathode plates sandwiching a separator and rolled up into a tasty charge with maximum power output. At either end of an  Ni-Cd battery  is an electrode, the point at which electricity goes in and leaves. Ni-Cd batteries use an active material called nickel hydroxide at the positive terminal and metallic cadmium at the negative terminal. Inside is a liquid alkaline electrolyte solution, usually potassium hydroxide. Cadmium is ...

  1. What is the OPGW Cable?   OPGW cable, also known as optical fiber composite overhead ground wire. The optical fiber is placed in the ground wire of the overhead high voltage transmission line to form the optical fiber communication network on the transmission line. This structure has both ground wire and communication functions, which is generally called OPGW optical cable.   Spiral Vibration Damper   2. What is the ADSS Cable?   ADSS cable, also known as the medium messenger cable, is a kind of composed of medium material, its all contain the necessary support systems, can be directly hung on the electric power poles of non-metallic fiber optic cable, it is mainly used for overhead high voltage transmission system of the communication line, can also be used for lightning areas, large span and other overhead laying under the environment of communication lines.   Parts of ADSS Accessories Some of the main parts of  ADSS accessories  include th...

    Insulators   are used in electrical equipment to support and separate electrical conductors without allowing current to pass through the insulator. Silicone rubber is the most widely used polymeric insulating material for high voltage products. Our polymer insulators offer excellent performance in a wide range of climates and harsh conditions, including coastal, desert and industrial environments.   Silicone rubber insulated polymer insulators offer unique properties and are installed all over the world.SAA Grid offers a wide range of insulators which, when combined with our flexible production methods, can provide a polymer insulator to meet your requirements.   Polymer insulators  are fast becoming the insulator of choice for recent transmission line projects. It is interesting to learn about the benefits of using polymer insulators. Here are some of the  benefits of using polymer insulators  in transmission lines. 110kV Polymer Suspension I...

Batteries for Electric Vehicles Energy storage systems, usually batteries, are essential for all-electric vehicles, plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs). Types of Energy Storage Systems The following energy storage systems are used in all-electric vehicles, PHEVs, and HEVs. Lithium-Ion Batteries Lithium-ion batteries  are currently used in most portable consumer electronics such as cell phones and laptops because of their high energy per unit mass relative to other electrical energy storage systems. They also have a high power-to-weight ratio, high energy efficiency, good high-temperature performance, and low self-discharge. Most components of lithium-ion batteries can be recycled, but the cost of material recovery remains a challenge for the industry. The U.S. Department of Energy is also supporting the  Lithium-Ion Battery  Recycling Prize to develop and demonstrate profitable solutions for collecting, sorting, storing, and ...

A  Power Bank  is an external battery that includes at least one USB port so that it can charge a device while away from an electrical outlet. Mobile power supplies come in a variety of capacities, which can affect the physical size of the charger as well as the charging time of the device and the mobile power supply. Knowing what a mobile power supply is helps to understand why each one is a little different, why some are better than others, and how to charge the one you have. While some guidelines are pretty standard, others will depend on the specifications and quality of your mobile power. You venture into unfamiliar territory and it happens: suddenly your phone's charge drops to 10% and you need to return the direction. If your mobile power has not yet been charged, you must find a place where you can charge your phone, and if you are lucky enough to find one, this still means you are stuck waiting. How often should you charge your mobile power? If your mobile power is de...
