We are commonly used are super five types of lines or six types of lines, although they are all cable, but the cable material is also divided into several kinds, most of them are in line with the national conditions of production!When buying a line, don’t be a pit!Don’t be greedy for cheap! First, four … Read more
We all know that copper and aluminum are the main materials of wire and cable, so who knows what advantages copper cable and aluminum cable have? 1.Low resistivity: the resistivity of copper-core cable is 1.68 times lower than that of aluminum-core cable, with less energy consumption. 2.Good ductility: the extension rate of copper for electrical … Read more
ABC cable is made of conductors of different materials mounted in insulated metal bushing, which is processed into a flexible and solid assembly.Armoured cable is generally fixed power cable, generally speaking, is fixed in a place and basically do not move, power line transmission of electric energy.The armoured cable includes armoured thermocouple, armoured thermal resistor, … Read more
Wire and cable in the process of operation, due to the existence of resistance will be heated.The resistance of the wire is generally very small, and its heating power can be expressed by the formula Q =I^2R.Q =I^2R indicates that: for a section of wire in use (R has been basically constant), the greater the … Read more
First tip: first understand the meaning of Aerial Bundled Cable (ABC) BS 7870 Standard Use code: A installation line, B cloth wire, C Marine cable, R flexible cable, … Read more
1 The radiation problem of the cable The radiation problem of cables is one of the most common problems in engineering. More than 90% of the equipment (mainly equipment containing pulse circuits) can not pass the radiation emission test because of the radiation of the ACSR conductor. There are two mechanisms of cable radiation. One … Read more
Electric welding machine cables are commonly known as welding handle wires. The two are actually the same kind of cable, with superior flexibility and good bending performance. The sheath material is made of natural rubber or neoprene mixture, which can be applied to different occasions. The neoprene compound sheath of the electric welding machine cable … Read more
In home decoration, water and electricity decoration is the most important, especially the electrical part, because it involves the safety of electricity use. If there is a problem with the electrical decoration, it may directly affect the safety of the family and the consequences are quite serious. Therefore, whether it is the wiring, connection, or … Read more
In the era of low-cost Internet access, the cost of the control system is critical. In the past ten years, the prices of modules and inverters have fallen by 90%, which has contributed greatly to the overall cost reduction of photovoltaic systems, but the cost of cables has not been reduced. In large-scale projects, cables … Read more
