Due to its low cost and easy installation, it is often used in indoor fixed connection scenarios with low protection requirements. Typical applications include:
Indoor lighting and appliance wiring: suitable for control wires of most lighting fixtures, as well as internal or connecting wires of small appliances such as fixed water dispensers and fans.
Broadcast audio system: Connecting amplifiers and audio equipment, transmitting audio signals is its "traditional art". The RVB 2 × 1.5mm ² (i.e. 2-core 1.5 square millimeters) specification is very common in engineering and is sufficient to meet the power requirements of conventional household and commercial speakers.
Fire alarm and security system: commonly used for signal line connection of smoke detectors, manual alarm buttons, etc. However, it should be noted that the RVB cable is not protected by a sheath and cannot be used outdoors or in humid environments.
Partial DC power supply scenarios: It is also applied in the power supply lines of low-voltage DC equipment such as access control systems, surveillance cameras, and LED lighting.
Other uses: instrument connection, general signal transmission, and other scenarios that do not require strict cable requirements
