Fire Wire-RVS

In electrical engineering, RVS wire is a commonly used cable type, which is widely used in various indoor and outdoor installation scenarios. This article will detail the definition, characteristics, application areas and installation considerations of RVS wires.

Definition of 1.

RVS wire, the full name of copper core PVC insulated stranded connection with flexible wire, is a kind of stranded by a number of copper core wire, the outer layer of PVC (PVC) insulation material wire. This wire is characterized by soft, flexible, good insulation performance, and has good electrical conductivity.

2. features

Flexibility: RVS wire has excellent flexibility, easy to bend and fold, easy to install in various environments.

Anti-interference: Due to the stranded structure, RVS wires can effectively resist electromagnetic interference and improve signal transmission quality.

Temperature resistance: The insulating material of RVS wires, polyvinyl chloride (PVC), has high temperature resistance and can work normally within a certain temperature range.

Environmental protection: RVS wire insulation material polyvinyl chloride (PVC) does not contain harmful substances such as halogen, in line with environmental requirements.

Safety: RVS wire has good insulation performance, not easy to short circuit and electric shock accidents, to ensure the safety of use.

3. Application Areas

RVS wire is widely used in the following fields:

Household appliances: such as air conditioners, refrigerators, washing machines and other household appliances power cord.

Lighting equipment: such as lamps, switches, sockets and other lighting equipment connection line.

Communication equipment: such as telephone, network equipment and other communication equipment transmission line.

Audio equipment: such as audio, television and other audio equipment cable.

Outdoor engineering: such as monitoring equipment, alarm system and other outdoor engineering wiring.

4. Installation Precautions

Indoor installation: When RVS wires are installed indoors, appropriate wire diameter and color matching should be used according to actual needs, and wiring should be carried out in accordance with safety regulations. When wiring, make sure that the terminals or terminals are in good contact to prevent poor contact from causing heat or short circuit. in addition,

RVS wires should be avoided in humid, high temperature or corrosive gas environment.

Outdoor installation: When installing RVS wires outdoors, environmental factors such as sunlight, wind and rain, temperature, etc. should be fully considered. Select the appropriate wire diameter and insulation thickness to meet the requirements of the outdoor environment. In addition, outdoor installation of RVS wire should take sunscreen, waterproof, anti-corrosion and other measures.

to extend the service life. During the installation process, care should be taken to avoid mechanical damage to the wire, such as friction, extrusion, etc. At the same time, wiring should be carried out in accordance with safety regulations to ensure a safe distance between the wire and other metal objects.

Wire diameter and color matching: The wire diameter of RVS wire should be selected according to the actual load current to meet the requirements of electrical safety and long-term use. In the color collocation, generally red, yellow, blue, green and other colors indicate the fire line, black or white indicates the zero line, yellow-green indicates the ground line. In practical applications, color matching can be carried out according to needs.

Safety specifications: When installing RVS wires, relevant safety specifications should be followed, such as "Building Electrical Design Specification" and "Low Voltage Distribution Design Specification. At the same time, it should ensure that the connection of the wire is reliable and firm, and avoid accidents caused by loose or poor contact. In the process of use, the wires should be inspected and maintained regularly, and they should be replaced in time if they are damaged or aging.

Summary:

As a common type of cable, RVS wire has the characteristics of flexibility, anti-interference and temperature resistance, and is widely used in household appliances, lighting equipment, communication equipment and other fields. During the installation process, attention should be paid to the different requirements of indoor and outdoor installation scenarios, and wiring should be carried out in accordance with safety regulations to ensure the safe use of wires.
