Discussion on Wire and Cable for Electrical Equipment
Wire and cable for electrical equipmentIncluding the direct transmission of electrical energy from the distribution points of the power system to electrical equipment, wires and cables with appliances as connecting lines, and various general or special wires and cables in measurement and signal control systems within electrical equipment.Wire and cable for electrical equipmentIs the most widely used, most varieties, the most complex technology products.
All electrical energy is transmitted directly from the final switchgear to various electrical equipment and appliances as connecting wires and cables. Internal connection and installation wires of various electrical equipment; wires and cables used in signal, measurement and control systems are collectively referred toWire and cable for electrical equipment.
Wire and cable for electrical equipmentThe basic performance requirements are still excellent and stable electrical performance; but because the working voltage of most products is not high, it is easy to meet. Other special requirements (for example, high temperature resistance, flexibility and shielding) must be innovated in material selection, structural design and processing technology. Therefore, it is necessary to carefully study various special properties with great differences before the need. measures have been met.
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.
