1. Cable raw materials are dampThe raw materials used for cable insulation and sheath are mainly plastic and rubber materials, and many kinds of materials with special functions are derived from them. When the material manufacturer fabricates the material, it will go through the processes of Compoun
Under low voltage, the insulation thickness mainly depends on the mechanical stress when the wire is bent, and the grade increases with the increase of the conductor cross section; the indicator for assessing whether the cable insulation layer can continue to work is still the voltage resistance lev
Highly flexible drag chain polyurethane cable product structure:Conductor: Multi-strand fine-twisted anti-bending oxygen-free fine copper wire conductor, in line with GB/T3956-2008 standard Class 6Insulation: High mechanical properties insulation TPEE materialCore wire identification: For cross-sect
1. Underground power cable faults are complex and changeable. The causes of power cable faults can be roughly classified into the following categories.1. Mechanical damageCable failures caused by mechanical damage account for a large proportion of cable accidents. Some mechanical damage is very mino
Wires and cables are the main carriers of power transmission and are widely used, especially in the transformation and new construction of urban and rural power grids. For this reason, this article specifically analyzes and identifies some inferior products based on several types of wires and cables
Japanese coaxial cable specifications, from thin and thick, there are 1.5C, 2C, 3C, 4C, 5C, 3D, 4D , 5D and other cable diameter distinction.Such as "3"refers to the outer diameter of the cable is about 5.4 mm, “5”refers to the outer diameter of the cable is about 7.4 mm, “C” refers to the impedance
Let us say , all else being equal, the length, and the cost . Let's explore the difference between them.Now, in the real world, it’s a bit more complicated than . We should consider production process , the material cost , the equipment in using and so on.Longer cables have more resistance (or, rat
Why Install Surveillance camera system ? Whether in their homes, businesses, or public areas, people want to know that they are safe from harm. Installing surveillance cameras gives people that sense of safety. After all, they are useful to prevent crime or help catch a perpetrator if a crime has be
1. What is Fiber Optic HDMI Cable?Before you get further knowledge of this definition, the question of “what does HDMI stands for? ”may pop up in your brain. HDMI stands for High Definition Multimedia Interface and is frequently used for transferring both HD digital audio and video information over
