  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 of each

  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 generation substations.   Po

    When the sun breaks through the sky, it's a great day to play golf. However, the sun can also bring harmful UV rays. You can be on the golf course for several hours per round, so  sun sleeves  are a great way to stay protected during the hot hours. Therefore, the  best sun sleeves  will provide UV protection on the course. Sun protection isn't the only thing they should give you, though. They should also keep you cool, provide plenty of flexibility, and stay in place without slipping on every swing. Great for outdoor sports For anyone who plays outdoor sports, runs, tries CrossFit for runners, etc., these may be the best choice for you due to the construction of the sleeves. The stitching of the sleeves takes into account muscle anatomy for a more comfortable, fluid sleeve that won't restrict your range of motion. Best for UV protection If you're a cyclist, many of the activities you do outdoors in the field, on the track or even on your bike will be upgraded by thi

  Some cleaning professionals wonder whether it really makes a big difference whether they choose a commercial hoover over one made for residential cleaning.   After all, the machines sold by large retailers for domestic use look important and are attractively priced. But are they the best machines for commercial use?   At Outan Environmental Protection, the nation's leading commercial equipment specialist, we are committed to providing high performance equipment for a more streamlined job. To provide more information, we have broken down the top 5 reasons to use a  commercial vacuum cleaner . Industrial Vacuum Cleaner (Charge Type)   How a typical commercial cacuum cleaner works and what to look out for? A  vacuum cleaner  uses air to create a suction vortex inside the machine. Just as we draw in air through a straw, vacuum cleaners draw in air and debris through a hose or agitator. The attachable power head and brush at the end of the hoover hose help to capture dust and debris o

Both gaskets and   O-rings   serve a similar purpose-sealing liquids or gases in a specific application. However, these two types of seals differ greatly in appearance and are designed for different environments.   When choosing a seal for your application, how do you know if a gasket or O-ring is right for you? Here are the key differences between gaskets and O-rings that you need to consider. O Ring What is an O-Ring? O-rings, also known as packing joints, are mechanical seals consisting of a round elastomeric material. They are designed to create a pressure-resistant sealing mating surface. In fact, some O-rings can withstand pressures in excess of 5,000 pounds per square inch (PSI). Even under extreme pressure, O-rings maintain their integrity while preventing liquids, gases or air from escaping the corresponding components used with them.   Although they are available in a variety of sizes, all O-rings are identical in shape. They consist of a ring-shaped elastomeric material with

According to Directive 1999/92/EC, steel tools are considered to be a source of ignition and therefore unsafe for use in the presence of explosive atmospheres. In such environments, non-sparking tools must be used. However, based on our experience in the industry worldwide, there are still many purchasing, maintenance, and even safety professionals who are not fully familiar with what non-sparking tools are and what the key criteria are for use when purchasing or using such tools. The most common non-sparking alloys are aluminum - bronze (Al-Bron) and copper - beryllium (Cu-Be), but what criteria should be followed when choosing one of these options? Explosion-proof Durable Hand Tools Aluminum Bronze Edging Spade Type of gas in the environment Despite its name, non-sparking tools do produce sparks (all metals produce sparks when they rub against each other). The difference between non-sparking too

Anti-corrosion coated steel pipe, through the anti-corrosion process, is to prevent corrosion or slow down corrosion in the chemical or electrochemical reaction that occurs during the transportation and use of steel pipes. According to our statistics, China's annual economic losses due to pipeline corrosion exceed 280 billion, and global annual pipeline corrosion losses amount to 500 billion. Anti-corrosion coated pipelines can effectively stop and slow down erosion, so the technology is widely used in industry. Anti-corrosion steel pipes are mainly used in petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields in China. Anti-corrosion steel pipes are divided into the following categories. IPN8710 corrosion When steel corrosion in more kinds of media, such as acids, alkalis, salts, oxidizers and water vapor, the coati
