Basic knowledge of wires and cables
Electric wires and cables are closely related to people's lives and property. So, how much do you know about wires and cables? Guangdong wire manufacturers will take you to a detailed understanding of the basic knowledge of wires and cables!
1. The difference between wires and cables is that wires are generally used for conducting metal wires that carry current. A cable is an insulated conductor composed of one or more insulated wires placed in a sealed sheath. The difference between wires and cables lies in the fact that wires are generally small in size and have a simple structure, but sometimes cables are classified as general wires.
2. The wire and cable models are numbered based on the different raw materials and uses of the product, while the specifications of the wire and cable are represented by the number of cores, nominal cross-section, and voltage.
3. There are thousands of wire and cable products widely used in various industries. Wire and cable generally have two purposes: one is to transmit current, and the other is to transmit signals. In general, it can be divided into six categories: electrical backup cables, power cables, overhead wires (non insulated wires), communication cables, and fiber optic cables.
4. The purpose of different types of cables is also different, such as flame retardant control wires and cables, which are generally used in places with flame retardant requirements.
