Pay Attention Before Install Low-voltage Cables When installing the low-voltage cable, ensure that the appearance of the low-voltage cable is complete. If the outer insulation layer of the low-voltage cable has noticeable stains, it should clean before installation. If the outer insulation layer of the low-voltage cable has obvious defects or serious scratches, you should … Read more
Development of Medium Voltage Cable With the economic development in recent years, the importance of medium-voltage cables has gradually become prominent, and the demand for medium-voltage cables in all walks of life is also increasing. Because of their characteristics, medium-voltage cables have different sizes and types. With special requirements, the structure of medium-voltage cables is … Read more
About the materials of construction, we always see the all alloy aluminum cable(AAAC cable). It is the highest cable product now. So what are the advantages and disadvantages of aaac cable? Creep Resistance of AAAC Cable The alloy material and annealing process of the aluminum alloy conductor reduces the tendency of the wire to “creep” … Read more
Different Appearance Between Power Cables and Control Cables The color of the insulated core of the control cable is generally black and white, and the low voltage of the power cable is generally color-separated. The standard for control cables is 9330, and the standard for power cables is GB12706. And the power cable requires the … Read more
The voltage level of the coaxial grounding cable should be determined according to the induced potential of the cable line. According to the past design experience, the voltage level of the coaxial grounding cable is generally 10kV; the cross-section of the coaxial grounding cable should be strictly selected according to the grounding current of the … Read more
The submarine cable project is recognized as a complex and difficult large-scale project by countries all over the world. Submarine cables are wrapped with insulating material and laid on the seabed for telecommunication transmission. And submarine communication cables and submarine power cables are both of submarine cables So, how are submarine cables laid? The Laying … Read more
Should you be a contractor, or maybe you possess a huge industrial business, chances are that you apply control cables. The control cable directly transmits electrical energy from the distribution point of the power system to the power connection line of various electrical equipment and appliances. There are some advantages to having these cables. Here’s … Read more
With the increasing development of the power industry, the capacity and reliability of the power communication network need to be continuously expanded and enhanced. At present, power special optical fibers used in power communication include optical fiber composite ground wire, optical fiber composite phase wire, all-dielectric self-supporting optical fiber cable, metal self-supporting optical fiber cable, … Read more
The current underground cables are generally of lower voltage level, and the line transmission with high voltage level is often overhead, which is mainly due to cost and technical factors. Ultra-high voltage power transmission refers to the use of 500kV-1000kV voltage level to transmit electric energy. If the 220 kV transmission index is 100%, the … Read more
Optical cable is a certain number of optical fibers form a cable core according to a certain method. Optical fiber cable is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. The integrated wiring project is a relatively complex project, so it is impossible to ensure … Read more
