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...

  The strain clamp is a metal component used to connect the transmission line tower, the wire, the lightning conductor and the insulator, or to protect the wire, the lightning conductor, the insulator and the like.   Basic requirements:  Preformed Rods  are generally made of cast steel and malleable cast iron. It is required that the line fittings should have sufficient mechanical strength to have good electrical properties for a part of the fittings connecting the conductors. In the manufacturing process, the line fittings should be free of burrs, traps, traps, and cracks. The surface should be smooth and the galvanized layer should be uniform.   The matching fittings should be of suitable specifications, no missing parts, no rust, and the screws and nuts should be well matched. The contact surface between the hull plate and the wire should be smooth, and the manufacturing quality and size should conform to the national standard.   Single Suspension for OP...

Pole line hardware,   often known as pole hardware fitting or pole line accessories, are an essential part of the construction of pole lines nowadays. Pole line hardware manufacturers classify these as utility pole mounting hardware, telephone pole component, and utility pole line hardware, depending on the type of use.   Manufacturers of pole hardware  classify them into pole mounting hardware, pole assemblies and pole line hardware depending on the type of use.   Pole line hardware is attached to complete the setup. It serves multiple purposes as it supports the power line and prevents its flow. The components required for a complete electrical installation setup are as follows: pulling clips, secondary U-clips, street light arms, pulling poles, anchors, secondary racks, yoke plates and pole straps. Preformed Line To ensure stability, only screws suitable for the specific requirements can be selected. As pole lines maintain and propagate utilities over a considerab...

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 Insulator Resis...
