BMA May Cancel The Project To Move All Overhead Cables Underground The Bangkok Metropolitan Administration (BMA) may cancel the project to move all overhead and telecommunication cables underground. This is because most telecom service providers have avoided the project due to its high investment cost, estimated at around 19 billion baht. Bangkok Deputy Governor Wisanu Subsompon said that at this stage, the city government has instructed its investment department as telecom service providers have shown little interest. Krungthep Thanakom, the project owner, has slowed down work. If the project is to be completed, the city expects the telecom regulator National Broadcasting and Telecommunications Commission (NBTC) to also share the cost, he said. So far, the BMA has laid 7.2 kilometers of power cable underground covering some roads in Bangkok. The estimated cost is 140 million baht, but the total distance of overhead cables in the capital is about 2,450 kilometers. Meanwhile, the Metro...

 Global High Voltage DC Market to Grow Rapidly According to a comprehensive research report by Market Research Future (MRFR), the global high-voltage DC transmission market is set to grow at a CAGR of 8.6% from 2022-2030. The rapid expansion of offshore wind power and the growing electricity demand are the major factors contributing to the growth of this market. The market for high-voltage DC transmission systems is expected to grow as more and more offshore wind power projects are being installed. Offshore wind energy can generate large amounts of electricity, which can then be distributed to areas with high electricity demand. In addition, as the electricity demand grows, the demand for cable-based transmission also grows. At the same time, the growth of the HVDC transmission market is stimulated by safety considerations, such as the lack of insulation on HVDC overhead transmission lines, which poses a significant risk to public safety. At the same time, factors such as the risin...

Low smoke and halogen-free cables have emerged in recent years, and they have become very popular for their low smoke and no pollution when burning. So how exactly are low smoke and halogen-free cable? Here let the ZMS cable editor take you to understand it. LSZH Cable Definition Low smoke halogen-free cable is an environmentally friendly cable that does not contain halogen, does not contain lead, cadmium, chromium, or mercury. And other environmental substances are made of rubber and do not emit toxic fumes when burned. Where the halogen pointer is: the value of all halogens ≦ 50PPM. The content of hydrogen halide gas produced after combustion <100PPM. PH value of hydrogen halide gas produced after combustion after dissolving in water≧4.3. Product burning in a closed container through a beam of light it's a light transmission rate≧of 60%. There are many types of low smoke and halogen-free cables , such as WDZ-BV, WDZ-RVS, WDZ-RVVP, etc. This cable has low halogen and low smoke ...

 The improvement of the global economic level has led to the rapid development of the cable industry, and it also consumes a large number of irreplaceable resources. More and more new power cable products are generated. Concentric cable is one of them. So, what is the concentric cable? What are its structural characteristics and how to put them into use? Let's let the ZMS cable take you to learn about it. Structural Characteristics of Concentric Cables Concentric cables are arranged into one-equation triangles. There are several copper conductors outside the insulation core to form a concentric conductor. The sum of the concentric conductor section is greater than or equal to the required neutral cross-section of the cable. Product Type Concentric cables and cross-linked polyethylene insulation power cables and polyvinyl chloride insulation electric cables are only different in the design structure. Power cables are different in design structures with cross-linked polyethylene ins...

What Is a Post-Insulator? Post insulator: It is a special kind of insulating control that can play an important role in overhead transmission lines. In the early days, post insulators were mostly used on poles, and gradually a large number of suspension insulators, usually made of silicone or ceramic, were developed from the ends of towers connected to high type high voltage lines to increase the creepage distance. They are called insulators. Power line insulators have two basic roles in overhead transmission lines , namely to support the conductor and to prevent current backflow, and these two functions must be ensured. Electrical insulators should not fail due to various electrical and mechanical stresses caused by changes in environmental and electrical load conditions, otherwise, they would not have the significant role of insulators and would impair the service and operating life of the entire line. What Is a Suspension Insulator? Suspension insulators are generally made of insula...
