Common Yanggu Cable Failure
CommonYanggu CableWhat are the faults?
Yanggu CableCommon faults of the line include mechanical damage, insulation damage, insulation moisture, insulation aging deterioration, overvoltage, cable overheating, etc. When the above-mentioned fault occurs in the line, the power supply of the faulty cable should be cut off, the fault point should be found, and the fault should be checked and analyzed, and then repaired and tested. Only after the fault is eliminated can the power supply be restored.
BuriedYanggu CableWhat are the safety requirements of the line?
Safety requirements for buried Yanggu cable lines include:
WhenYanggu CableWhen crossing each other, the high voltage cable should be lower than the low voltage cable.
When the Yanggu cable crosses the railway or highway, it should be protected by the pipe, and the protective pipe should extend 2m from the track or road surface.
The distance between the Yanggu cable and the building foundation should ensure that the cable is buried outside the water of the building; when the Yanggu cable is introduced into the building, it should be protected by pipelines, and the protection pipeline should also exceed the periphery of the building.
Wire Yanggu cable industry development:
Wire Yanggu cable industry is China's second largest industry after the automotive industry, in the world, China's total output value of wire and cable has surpassed the United States, becoming the world's largest wire and cable producer.
Mineral insulated fireproof cable manufacturers,Yanggu cable manufacturerTo tell you, China's sustained and rapid economic growth has provided a huge market space for cable products. The strong temptation of the Chinese market makes the world focus on the Chinese market. In just a few decades of reform and opening up, the huge production capacity of China's cable manufacturing industry has impressed the world. With the continuous expansion of China's power industry, data communication industry, urban rail transit industry, automobile industry and shipbuilding industry, the demand for wire and cable will also increase rapidly, and the wire and cable industry has great potential for future development.
What are the main points of purchasing wires and cables? Let's take a look. As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting circuits, household appliances, etc. Its quality directly affects the quality of the project and the safety of consumers' lives and property. There are many wire varieties on the market, and appropriate wires should be used according to their own power load.
What are the precautions for wires and cables? Let's take a look. Common cable faults: wire surface markings-according to national standards, the wire surface should have continuous markings of the manufacturer's name, product model and rated voltage. This helps to find the manufacturing plant in time when there is a problem during the use of the wire, and consumers should pay attention to this when buying the wire.
There are many kinds of wire and cable products for electrical equipment on the market, which are difficult for ordinary consumers to distinguish. So what are the main categories of wire and cable products? What are the product naming principles of wire and cable? The editor brings you a brief understanding of relevant content knowledge.
The wires and cables for electrical equipment are mainly used for internal or external connection of electrical equipment, low-voltage transmission lines and various electrical signal transmission lines. Generally speaking, except for power cables, communication cables and magnet wires, most insulated wires and cables are classified as wires and cables for electrical equipment.
Electrical equipment with wire and cable is a large class of wire and cable products, a wide range of applications, many varieties, many series, large output, process type complex. The rated voltage of wires and cables for electrical equipment is low, and the working voltage is 450/750v and below, which is not more than 0.6/1kv. The working voltage of signal and instrument cables is usually 300/500v and below. The ampacity of the cable is determined according to the requirements of the cable.
Low voltage power cable winter pay attention to matters? As the weather gets colder and colder, manufacturers of low-voltage power cables usually become more difficult, which brings inconvenience to construction. Here are some precautions for winter construction. Let us take a brief look.
