Introduction to Single Core Cables

Single core refers to having only one conductor within an insulation layer. When the voltage exceeds 35kV, most single core cables are used, and the relationship between the wire core and the metal shielding layer can be seen as the relationship between the coil and the iron core in the primary winding of a transformer. When a single core cable core passes through an electric current, there will be a magnetic field wire cross-linked with aluminum or metal shielding layer, causing induced voltage to appear at both ends.

A single core wire is a commonly used wire in home decoration, with only one conductor core inside the insulation layer and no sheath layer. Common uses include single core wires for household lighting, sockets, air conditioning, and more. Single core wire classification.

Single core wires include BV wires, RV wires, and BVV wires. BVR wires are multi-core wires with relatively soft materials and many small copper wires twisted together.

classification

Single core wires include BV cables, RV wires, and BVV wires. BVR wires are multi-core wires with relatively soft raw materials and several small copper core wires twisted together.

colour

Commonly used single core wire colors include red, yellow, blue, green, black, white, dual color (yellow, green), and brown.

Advantages and disadvantages

Advantages: Due to the small cross-sectional area ratio, it is not easily oxidized, resistant to short-circuit current impact, and has a relatively long service life.

Disadvantages: The wire is relatively hard, making it inconvenient to pull wires in some places. After bending, it is difficult to straighten it, and multiple bends can easily damage the wire.

purpose

The purpose of a single core cable is a type of power transmission equipment consisting of a conductor and insulation material. It has a wide range of applications and can be used in various fields such as construction, industry, transportation, communication, etc.

In the field of construction, single core cables are mainly used for power transmission and lighting. It can transmit electricity from the power source to various electrical equipment inside the building, such as lamps, sockets, televisions, etc. In addition, single core cables can also be used for lighting systems in buildings, providing a bright and comfortable environment for people.

In the industrial field, single core cables are mainly used for power transmission and control of machinery and equipment. It can transmit electricity from the power source to various machine equipment, such as machine tools, production lines, etc. In addition, single core cables can also be used in the control system of machine equipment to achieve control and adjustment of machine equipment. In the field of transportation, single core cables are mainly used for power transmission and signal transmission in transportation facilities such as railways, subways, and highways. It can transmit electricity from the power source to various transportation facilities, such as signal lights, trams, subways, etc. In addition, single core cables can also be used for signal transmission in traffic facilities, achieving control and regulation of traffic facilities.

In the field of communication, single core cables are mainly used for signal transmission in communication equipment such as telephones, televisions, and computers. It can transmit signals from communication devices to other devices, such as telephones, televisions, computers, etc. In addition, single core cables can also be used for power transmission of communication equipment, providing power support for communication equipment.
