Zimbabwe exports 4-core hollow optical fiber
This landmark partnership is set to revolutionize Zimbabwe's digital landscape by launching a new high-capacity national fiber network. Welcome to Zimbabwe electronic Government Procurement (eGP) System. The eGP System is a secure web-based application managed by the Procurement Regulatory Authority of Zimbabwe (PRAZ) to enable all public bodies and suppliers to electronically conduct public procurement proceedings. The eGP System. CAFCA is the only cable manufacturing company in Zimbabwe. CAFCA's primary market is Southern. Hollow-core optical fibers (HCFs) have unique properties like low latency, negligible optical nonlinearity, wide low-loss spectrum, up to 2100 nm, the ability to carry high power, and potentially lower loss then solid-core single-mode fibers (SMFs). These features make them very promising for. A 4-core SM/MM fiber cable is a durable optical cable containing four glass fibers for high-speed data transmission, available in Single Mode (9/125) for long distances or Multimode (50/125) for shorter runs. Paratus Zimbabwe, a subsidiary of the Paratus Group, has announced a significant Indefeasible Rights of Use (IRU) agreement with PowerTel Communications, a. Linfiber Technology (Nantong) Co. -
Basis for classifying dustproof levels of network cabinets
IEC 60529 has been developed to rate and grade the resistance of enclosures of electric and electronic devices against the intrusion of dust and liquids. It also rates how easy it is for individuals to access the potentially hazardous parts within the enclosure. Here's the direct answer: For most users, an IP54–IP55 wall- or floor-mounted cabinet with replaceable panel filters, rear cable grommets, and passive ventilation (not sealed fans) delivers the best real-world protection without overheating risk. If you're a typical user, you don't need to. That's where dust proof IP ratings come in. Our IP rating guide is written based on IEC 60529. What is an IP Rating? Confused by codes like “IP65” on a spec sheet? You're not alone. It matters in every industry—from solar energy systems and telecom base stations to LED lighting, food processing plants, and marine control. Whether you're managing factory floor installations, outdoor telecom cabinets, or smart building control panels, understanding the distinctions between IP54, IP55, and IP66 ratings will help you protect sensitive electronics against specific environmental challenges.

Decentralized Energy Internet
In this deep dive, we unpack how software, storage, market reforms, and smarter infrastructure could enable a more decentralized, resilient “energy internet” for the 21st century. Sustainability is crucial for the future of our planet, which is particularly important for urban. Can decentralized energy get good enough, fast enough? RECAI 60: Integration of rising amounts of renewables into grids must improve significantly if markets are to meet their decarbonization goals. This article is a summary of the 60th edition of the Renewable Energy Country Attractiveness Index. Tracing the evolution of the US electric grid from its centralized, monopolistic origins to today's fragmented and overstretched system. The rise of distributed energy resources, electrification, and extreme weather have pushed the grid to a breaking point. Innovations such as microgrids and virtual power plants (VPPs) are aggregating resources to offer grid services like demand response and frequency. Decentralization describes the activity needed to make the energy system more sustainable and resilient, using decentralized energy resources technology like solar, wind, hydro, geothermal, biomass, energy storage, energy efficiency, and smart grid. -

How to make cable trays when cables are angled
You can buy a manufactured 90 degree bend or make one on a cable tray bending machine but in this video I show you how to make one using a metal bar. The first one is when you know the angle you want to create and the second is when you want to make a parallel off-set. How to calculate size of cut-out section (D) for a pre-determined angle set Eg. How to cut Oglaend System Support Channels, Cable Ladders and Cable Trays. Oglaend System manufacture and deliver Multidiscipline modular bolted support systems, cable trays, cable ladders and accessories for complete installation and containment of Instrument, Electrical, Telecom, HVAC and Piping. For Cable Tray Installers—This publication is intended as a practical guide for the proper installation of cable tray systems. Cable tray systems design shall comply with NEC Article 392, NEMA VE 1, and NEMA FG 1 and follow safe work practices as described in NFPA 70E. -
