Causes and treatment methods of water inflow of wires and cables
Wire and cableThe fault includes water in the cable. Wire and cable water is a very tricky thing. So far, there is no effective way to solve it. The usual treatment method is the intermediate joint, and the other is to replace the entire wire and cable.
The harm of water entering the wire and cable: In view of the fact that water enters the wire and cable, the damage is only a matter of time, and it will also cause damage to the cable. The effective method is to take preventive measures first. Next, let me introduce how to deal with the water in the wire and cable.
causes of wire and cable water:
WhenWire and cableWhen laying through the pipe, the outer insulation layer is broken and water penetrates into the cable.
After laying the wire and cable, the cable heads at both ends are not sealed and exposed to the air for a long time.
If the laying and storage work is not done well, the sealing of the terminal is not good, causing water vapor to enter the cable.
It also includes local failures caused by bumps in the operation of the wire and cable and penetration into the cable.
Wire and cable water treatment method:
LayingWire and cable for electrical equipmentAfter that, please arrange the cable head in time and complete the wiring to eliminate the hidden dangers in the communication seat.
If there is only water at both ends of the cable, just cut off both ends and reconnect the cable head.
If wires and cables for electrical equipment have an obvious water inlet point, the cable must be cut near the water inlet point and intermediate connections must be made.
If there is water in the outdoor cable well or cable channel, try to fix the cable with the highest possible bracket.
Periodically conduct pressure leakage tests on wires and cables for electrical equipment to understand the operating status of the cables.
All in all: the way to deal with wire and cable water is to prevent! Because once the cable enters the water, it is basically scrapped. Therefore,Yanggu cable manufacturersRemind everyone that cables must be checked and maintained regularly in daily use,Control cableIt's the same.
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.
