Encrypted transmission for automated distribution network
In this paper, the random forest and neural network algorithm are used to encrypt the data of power system equipment, and all the data are classified data and non-confidential data by random forest algorithm. Non-confidential data can be transmitted directly in the form of plaintext in the network. With the construction of the power Internet of things, power equipment, vehicles, smart homes and various terminals are linked together, we have entered an era of interconnection of all things.

400g data transmission optical module
400G transceivers are high speed optical modules designed for 400Gbps data transmission. They are commonly used in data centres, cloud computing, high performance computing (HPC) and AI environments. PAM4 (4-Level Pulse Amplitude Modulation): This is the predominant modulation technique used in 400G modules. The Cisco 400G QSFP-DD Ultra Long-Haul Coherent Optics Module enables 400G traffic anywhere over dense wavelength division multiplexing amplified networks, and is available in both C-band and L-band. This shift is driven by multiple forces: hyperscale data centers require greater east-west bandwidth to support massive internal data. With the 400G speed-up, the optical interconnect infrastructure has seen significant developments, giving rise to several interface designs and form factors, such as QSFP-DD and OSFP. This article introduces the fundamentals, standards, and market trends surrounding 400G optical modules, a core technology for modern AI and cloud networks.

Case Study of Fire-Resistant Cable Trays
Based on the engineering practice of an oil storage company, this study proposes a modification scheme that entails spraying fire-retardant coatings on the outer surface of a cable tray to delay the failure times of the cables in the tray. What Happened: On 6 January 2013, a fire erupted in the Huidong Constellation Building (Jinan, China). Through these tests the aim was to learn more about thermal conductivity properties in fire conditions and what effects it would have on the tray itself and how long the installed cable could maintain circuit integrity. The documents may come from teaching and research institutions in France or abroad, or from public or pri-vate research centers.

Case Study on Relay Protection Upgrade
This project covered the removal of existing GEC mechanical protection relays and installing and commissioning Schneider MiCom relays. Abstract—Short transmission lines connected in a looped configuration are typical of some industrial power systems, but they can present numerous protection coordination difficulties because of their inability to effectively use underreaching elements. These clean energy sources, connected through inverters and flexible transmission systems, are transforming traditional grids based on synchronous generators into more flexibl cant challenges to system stability. Maintenance costs are reduced, while internal watchdogs alert the user if the relay has a problem. Modern, second-generation numeric relays offer a variety of secure communications capabilities for.
