Four main factors to help you choose the right flexible control cableHigh-flexible cable is a kind of cable with better flexibility. It has been widely used in household and industrial power, which greatly facilitates people's lives. At the same time, its development has been highly valued by the national power supply network. Flexible contr...
Exploring the production process of steel wire armor cable armorCables that need to withstand large mechanical forces should have an armor layer. The most common types of armored cables are steel tape armored cables and steel wire armored cables. Steel wire armored cables are further divided into thick steel wire armored cables (usually us...
Factors affecting the flow of high-voltage insulated overhead cablesThe high-voltage insulated overhead conductor has the structure of a common grounding clamp, and an external gap discharge device is added. The piercing electrode at the upper end can penetrate the wire insulation layer to make the lightning protection grounding ring a...
Identify the inferior quality wire and cableCharacteristics of shoddy wires1 The cable length is not enoughThe main means used by unscrupulous manufacturers is to make an article on the length of the wire and cable. The actual length of the wire and cable is less than the nominal length, and the pricing is performed according to the nominal length.&n...
Analysis of the main performance of control cablesThe control cable is a PVC insulated and sheathed control cable suitable for industrial and mining enterprises, energy and transportation departments, and control and protection lines for AC-rated voltages up to 450/750 volts.Performance Characteristics：1. DC resistance: 20 ° C, 0.4 mm cop...
Factors affecting the overall tensile performance of overhead cablesThe extra breaking force of the wire is calculated from the strength of all aluminum single wires and reinforcements. However, the actual breaking force will have a certain bias with the actual calculated value. The secondary reason is that the strength of every single line has n...
Common fault types and characteristics of overhead cablesOverhead transmission lines are the main components of the power system and transmission network. They undertake most of the industrial and domestic transmission tasks and are also the most vulnerable parts of the power system. The common faults are classified according to their n...
Function introduction of control cable with shieldingThe control cable is generally composed of a conductor, an insulating layer, an outer wrap, and an outer sheath. The function of the insulation layer is to prevent the occurrence of electric leakage accidents and ensure the safety of electricity consumption.The function of the outer sh...
Ways to ensure the quality of control cablesThe appearance quality of the cable is very important. The first impression given to the user is the appearance and quality of the product. Therefore, all good products pay attention to appearance quality. For example, flame-retardant shielded control cables, low-smoke halogen-free control ca...
Reasons for not wrapping and insulating high voltage linesThe transmission voltage of high-voltage transmission lines is mostly above 10,000 volts, and the voltage of some lines is as high as 100,000 volts and 500,000 volts. If the insulation layer is to be provided for such a line, the thickness of the insulation layer of ordinary wires is far from e...
