Safety of Yanggu Cable
Yanggu CableIt is usually a rope cable twisted by several or several groups of wires (at least two in each group). Each set of wires is insulated from each other and is often twisted around a center. The entire enclosure is covered with a highly insulating coating. Most of them are installed in the air, underground or underwater for communication or power transmission. Cable according to the use can be divided into power cable, communicationYanggu Cableand control cables. So, are there any safety requirements when using Yanggu cable? What are its protective measures? How to store it? Details are as follows:

When Yanggu cables cross each other, high-voltage cables should be lower than low-voltage cables.
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 foundation of the building should ensure that the cable is buried outside the water of the building; when the cable is introduced into the building, it should be protected by pipes, and the protective pipes should also exceed the periphery of the building.
UseYanggu CableProtective sleeve protection cable can achieve the following advantages:
Good corrosion resistance, long service life, can be used in wet saline-alkali land.
It has good flame retardancy and heat resistance, can be used for a long time under 130 without deformation, and does not burn in case of fire.
High strength and rigidity. It can be directly buried under the traffic lane without adding a concrete protective layer, which can improve the construction progress of the roller fast cable project
The Yanggu cable protection sleeve, whether it is a pipe or a pipe fitting, has a certain degree of flexibility and can resist damage caused by external pressure and foundation settlement.
It has good anti-external signal interference performance.
The inner wall is smooth and will not scratch the cable. The design adopts socket connection mode, which is convenient for installation and connection. A rubber seal ring is added at the joint, which not only adapts to thermal expansion and contraction, but also prevents sediment from entering.
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.
