Analysis of the main performance of control cablesThe control cable is a PVC insulated and PVC 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 copper...
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...
Explanation of comparison between copper-core and aluminum-core cablesWith the widespread dissemination of wire and cable, people are increasingly aware of its related knowledge.We all know that copper and aluminum is the main material of wire and cable, and so do copper-core cable and aluminum-core cable that has more advantages. The followi...
Introduction of control silicone rubber copper tape cableThe processing method of ceramic refractory silicone rubber and ordinary high-temperature silicone rubber compound is exactly the same. It has excellent extrudability and moldability and can be directly extruded and vulcanized into wire and cable with silicone rubber wire and c...
Control cables play a more important role in lifeThe core of the control cable is generally copper core, nominal cross-section 2.5mm2 and below, 2 to 61 cores; 4 to 6mm2, 2 to 14 cores; 10mm2, 2 to 10 cores.The working temperature of the control cable is: Rubber insulation for 65 ° C, PVC insulation for 70 ° C, and 105 ° C are two levels.Control cables for compu...
Specific introduction to the shielding effect of power cablesThe power cable is still a low-voltage cable. If it is high-voltage, there will be a layer of similar resin filling inside. This is an insulating effect. In high-voltage cables, this layer is an important part of the insulation. There is no such thing as low pressure. Then there will be some...
Comparison of copper and CCA insulated cable performanceCopper-clad aluminum is a concentrically coated copper layer on the surface of aluminum or aluminum/steel alloy core material, which is drawn and has a copper layer thickness of 0.55 mm or more.Copper-clad aluminum and pure copper can be compared in the following three aspects:Mechanical Charac...
Aluminum alloy aluminum stranded wire performance enhancement techniquesThe rated breaking force of the wire is calculated from the strength of all aluminum single wires and reinforcements. However, the actual breaking force will deviate from the actual calculated value. The main reason is that the strength of every single wire is not fu...
Cables are an important part of the power transmission system, and their role is to transport electrical energy from the power station or substation to each electricity-using terminal. With the progress of technology, there are more and more types of cables, among which the common ones are mineral cables, flame retardant cables, fire resistant ca...
Advantages and disadvantages of high-voltage insulated overhead linesThe use of insulated wires instead of bare wires for high-voltage insulated overhead lines of 10kV and below is a new technology in the construction and reconstruction of urban distribution networks. It has a series of advantages of buried cables and can overcome many shortco...
