The structure and materials of cable products are the structural elements of wire and cable products, which can be generally divided into four main structural components: conductor, insulation layer, shield and sheath, as well as filling elements and pull elements. According to the use requirements and application occasions of products, some products are extremely simple in structure, with only one structural part of conductor, such as overhead bare conductor, catenary conductor, copper aluminum busbar

China is a large country of energy production and consumption, but its energy exploitation and utilization technology is backward, the proportion of traditional high energy consumption industries is significant, and the energy consumption per unit GDP lags behind that of developed countries. The contradiction between energy supply and demand will further intensify. At the same time, China is the largest developing country in the world, with rapid economic development, and the growth rate of energy consumption in China ranks first in the world

Photovoltaic cable Photovoltaic cable is one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is increasingly widely used in China. In addition to the rapid development of photovoltaic power plants supported by the government, private investors are also actively building plants and planning to put into production solar modules for sale worldwide. Many countries are still at the learning stage. No doubt, in order to

Mining cables are divided into armored cables, rubber sheathed cables and plastic cables. 1. Armored cable The so-called armored cable is armored with steel wire or steel tape. Its biggest advantages are high insulation strength and strong tensile resistance, so the steel wire armored cable is suitable for vertical shaft or steeply inclined roadway, and the steel belt armored cable is suitable for horizontal roadway or gently inclined roadway
