The design of submarine optical cable: anti-corrosion, anti-seepage, but also against sharks, compared with coaxial cable, optical fiber is quite obvious advantages, but its own is quite fragile, so this protection of optical fiber submarine cable peripheral protection structure put forward higher requirements. Specifically, the design of submarine optical cable must ensure that the internal … Read more
The COVID-19 pandemic shows the power market’s preference for renewables in the face of falling demand, and the clean energy transition is likely to accelerate, Moody’s reports. “Coal generation has continued to decline, while renewable energy has shown greater resilience in key markets in the United States, Europe, China and India,” the report said. As … Read more
The characteristic of photovoltaic cable is determined by its special insulating material and sheath material, which is called cross-linked PE. After irradiation by the irradiation accelerator, the molecular structure of the cable material will change, thus providing its performance in all aspects. Photovoltaic cables are often exposed to sunlight, and solar systems are often used … Read more
Aluminum alloy power cable is a new material power cable with AA8030 series aluminum alloy material as the conductor, adopting advanced technology such as special roll forming wire twisted production process and annealing treatment. Alloy power cable made up for the inadequacy of previous pure aluminium cable, although there is no improve the conductive properties … Read more
High temperature superconducting cable is a kind of power facility that adopts unimpeded superconducting material that can transmit high current density as the conductor and can transmit large current. It has the advantages of small volume, light weight, low loss and large transmission capacity, and can realize low loss, high efficiency and large capacity transmission. … Read more
Analysis of the main products of cable raw materials (copper): According to the monitoring data of the cable network, the domestic spot copper price continued to fall sharply in July, and the overall copper price fell during the month. The average spot copper price in the beginning of the month was 42585. RMB/ton, the average … Read more
One is the conductor structure.The conductor of cable is usually made of high purity copper or aluminum of certain toughness and strength with good electrical conductivity. Conductor sections are commonly used in circles and sectors. A conductor with a smaller section (less than 16 square meters) is made of a single copper wire, while a … Read more
What are the advantages of environmentally friendly cables compared to other traditional cables? Compared with ordinary cables, environmentally friendly cables have the following advantages: The first is to have high flame retardancy. We all know that the flame retardant performance of the cable is very important. It fully ensures the safety and fire resistance of … Read more
AAC cable products have been in the western market for many years, largely because the company needs cheap cables in order to save money. Because aluminum costs less than copper, AAC cables are ge detecty cheaper than all copper products. As a result, many buyers with tight budgets will look for cheaper and more cost-effective cable products. They may not realize that what they … Read more
