description: In the 1970s, there was a "20kHz revolution in the history of power supply in the world. It refers to the application of 20kHz switching frequency combined with pulse width modulation (PwM) in the power supply field. It has begun to develop towards high frequency above 100kHz, thus making the switch The power supply has three advantages of high efficiency, small size and light weight. In order to meet the market demand for miniaturized and high-efficiency switching power supply, the high-frequency potential of the existing domestic switch components should be fully utilized, and pulse width modulation technology should be used. Pressure auxiliary power supply and direct high-voltage DC conversion. Optimize the circuit structure, so that the switching frequency reaches 120kHz, the output power is 150W and other indicators and the performance is stable and reliable. This document presents the circuit design and fabrication of a 120kHz PWM switching power supply. The attached circuit diagram for its circuit diagram, circuit diagram analysis and more can be found in the PDF document. Fire Retarding FRP Support Cable Tray
Fire Retarding FRP Support Cable Tray is a type of cable tray made from Fiber Reinforced Polymer (FRP) material that is designed to resist fire and prevent the spread of flames in the event of a fire. This type of cable tray is commonly used in industrial and commercial settings where fire safety is a concern.

FRP Support Cable Tray is made from a combination of fiberglass and resin, which makes it lightweight and strong. It is also resistant to corrosion, chemicals, and UV radiation, making it ideal for use in harsh environments. The fire-retarding properties of FRP Support Cable Tray are achieved by adding fire-retardant additives to the resin during the manufacturing process.
The design of FRP Support Cable Tray is similar to that of traditional cable trays, with a series of rungs or channels that support and protect cables. The rungs are spaced apart to allow for ventilation and prevent the buildup of heat, which can increase the risk of fire. The tray can be mounted on walls, ceilings, or floors, and can be customized to fit the specific needs of a particular installation.
One of the key benefits of FRP Support Cable Tray is its fire-retarding properties. When exposed to fire, the tray will not ignite or emit toxic fumes, which can help to prevent the spread of flames and reduce the risk of injury or damage to property. This makes it an ideal choice for use in areas where fire safety is critical, such as chemical plants, oil refineries, and power stations.
In addition to its fire-retarding properties, FRP Support Cable Tray is also easy to install and maintain. It can be cut to size on-site using standard tools, and can be installed using a variety of mounting options. The tray is also easy to clean and does not require any special maintenance or cleaning procedures.
Overall, Fire Retarding FRP Support Cable Tray is a reliable and effective solution for protecting cables and preventing the spread of fire in industrial and commercial settings. Its lightweight, corrosion-resistant, and fire-retarding properties make it an ideal choice for a wide range of applications, and its ease of installation and maintenance make it a cost-effective solution for businesses and organizations of all sizes.
