The difference between armored and unarmored cablesWhat is an armored cable:ClassificationThe armor is divided into steel belt armor (22, 23), thin steel wire armor (32, 33), and thick steel wire armor (42, 43).Steel cable armored cable models are VV22, VVP22, ZRVV22, and NH-VV2.Control cable steel cable armored cable, models are KVV22, KVVP2, KVVP22...
SUBTITLE: Power Cable structures are simple and complex. They include conductor, metal shield, Semi-conductive shield, insulation, and cover.ABSTRACT: The components of the cable structure are subject to strict requirements and regulations and are strictly enforced according to the standards. Each structure has its own characteristics an...
Characteristics of control cables and measures to prevent electrical interferenceThe cable performance is clear, and it is best to know when it is used. We also want to know the actual performance when we pay attention to the control cable so that we can know whether it is the best when analyzing it. Or some other advantages, you should st...
Reasons for high voltage cables without cladding insulationBecause it is not necessary to provide a high-voltage insulation layer, it is also a waste of money.The 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 laye...
Cable Quality Control Checks During ProductionThe inspection is understood according to the relevant standards: through the use of observation and judgment, appropriate combined measurement, and comprehensive evaluation conducted by the test. The purpose of the inspection is to meet the customer's expectations for product quality, an...
Reasons for difficulties in finding faults in low-voltage cablesThe fault finding of low-voltage cable is not much different from that of high-voltage cable. The principle, method, and technology are exactly the same. It is only through when the flashover test and fixed point, the impulse voltage is properly controlled to avoid damage to t...
Characteristics and installation of fire-resistant flame retardant cablesFire-resistant XLPE insulated PVC sheath power cableIt can be laid indoors, in tunnels, and in pipelines, and can withstand certain laying traction, but the cable can not bear external force, and single-core cable is not allowed to be laid in the magnetic material pipeli...
Introduction of Special Cable ClassificationHigh-Temperature ResistanceHigh-temperature wire and cable are required in aerospace, rolling stock, energy, steel, non-ferrous metal smelting, oil extraction, electrical machinery, construction, and other fields. The long-term continuous working temperature of 125 °, 135 °, 150 °, 180 ...
Introduction to the use of control cablesControl cables are types of instrumentation cables that measure and regulate the automation process. They are used as interconnections between static and mobile equipment. Surging demand for control cable products in construction, building, rail, and transport can fuel this region.Based on pro...
Advantages of copper-core cables compared to aluminum-core cablesHigh StrengthAllowable stress at room temperature, copper is 7~28% higher than aluminum. Especially the stress at high temperatures, the difference between the two is even more distant.Low ResistivityThe electrical resistivity of the aluminum core cable is about 1.68 times higher t...
