Basic definition of wire and cable
Definition of wire and cable: wire products used to transmit electrical (magnetic) energy, information and electromagnetic energy conversion. There is no strict boundary between "wire" and "cable. Generally, products with a small number of cores, a small product diameter, and a simple structure are called wires, those without insulation are called bare wires, and others are called cables; conductors with larger cross-sectional areas (greater than 6 mm²) are called large wires, and smaller ones (Less than or equal to 6 mm²) is called small wires, and insulated wires are also called cloth wires.
Shandong Yanggu Haohui Cable Co., Ltd.Located in the capital of Dongyi, the ancient city of thousands of years, the hometown of Wu Song-Shandong Yanggu Xiangguang (national) ecological industrial demonstration park. The company's leading products are:Mineral fireproof cables, PVC insulated control cables, PVC insulated power cables, XLPE insulated power cables, overhead insulated cables, aluminum stranded wires and steel-core aluminum stranded wires and cables, cross-linked polyolefin insulated wires and cables, high-life wires and cables, PVC insulated unsheathed (soft) cables and wiresSuch as series of products
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.
