Maintenance of wire and cable
Wire and cableThe service life depends on the quality of the cable and the environment in which the cable is installed. This wire and cable is mainly insulated by an outer wrap. For a long time by corrosive gas corrosion, insulation performance gradually decreased, slowly aging hard, brittle or fall off. It is very dangerous for wires and cables to lose their insulation properties. If the two cables touch each other or the live wire touches something connected to the earth, there will be a power outage, which will increase the temperature of the local wires, generate sparks, and cause a fire. Therefore, please note:
Wire and cable should not be damp, heat, corrosion or scratch. Wires and cables should be checked for a certain period of time, and any faults should be replaced in time. Wires and cables should not be overloaded. Frequently check the use of home appliances and lines, timely maintenance and repair. For the lines of old buildings, it is found that they are flooded or wet, especially the lines are in disrepair and aging. Please ask the electrician to repair them immediately. For lines that are easily soaked by floods, electricians should be required to move the lines and take overhead and moisture-proof measures. In rainy days, if the power is cut off immediately, ask the electrician to check the reason and assign special personnel to take care of it.
Yanggu Cable FactoryTell you, wire and cable maintenance:
The surroundings of the machine should be kept clean and tidy at all times. There shall be no oil, water or material or product falling off the ground. The waste products caused by production should be concentrated in time and disposed of quickly. Wipe and clean the surface of the machine and whether the machine is well maintained. Check whether the surface of the machine is always clean, whether the tools are placed according to regulations, and whether items that should not be placed are placed on the surface of the machine; add lubricating oil or cooling oil according to regulations, and regularly check whether the oil supply system is unblocked; during the operation of the machine, there is no Abnormal sound or vibration, regularly check and tighten the fasteners; whether the transmission belt is loose or deteriorated during use, should be replaced; whether all machine safety doors, safety barriers, safety covers, safety switches and limit devices are complete, normal and effective; according to the requirements of the tally card, the operator must achieve "three good" and "four meeting"; that is, good management, good use and maintenance; able to use, check, maintain and troubleshoot.Control cableThe maintenance work also needs to be done in place.
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.
