Wire and cable products for electrical equipment
One of the five major categories of wire and cable isWire and cable for electrical equipmentWhile we understand the basics of this type of cable, high-voltage cables are equally important.
Wire and cable for electrical equipmentFrom the power distribution point of the power system, the electric energy is directly transmitted to each electrical equipment, and the power connection line of the appliance is also the wire and cable used. The electrical installation lines and electrical cables for control signals in the equipment used in industrial, agricultural, industrial and mining enterprises use such products. Electrical equipment with the widest range of use of wire and cable, the most varieties. Generally, the structure and performance of the product will be determined by combining the characteristics of the equipment used and the environmental conditions used. So,Wire and cable for electrical equipmentIn addition to a large number of general products, there are many special products and special products.
In the wire and cable, according to the use of the product will be divided into eight categories. Each type of product contains a different variety of cables,Wire and cable for electrical equipmentOne of the most complex. We hope that we can learn to have a comprehensive understanding and mastery of them, and pay attention to their structural characteristics, performance indicators, environmental conditions and use requirements in the process work, so as to customize reasonable technical specifications.
For low pressureWire and cable for electrical equipmentAfter the insulation material is selected, when determining the insulation thickness, the electrical performance is generally not our attention consideration, but the mechanical performance is the main factor. According to the mechanical properties to determine the insulation thickness, insulation to meet the mechanical properties of the requirements, the electrical properties will be met accordingly. Therefore, when the voltage level of the product is increased, the insulation thickness should be appropriately increased.
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.
