RVB-Copper Core Flat Sheathless Flexible Cable

RVB cable is a parallel multi-strand soft wire with a flat appearance, similar to a telephone line but without a sheath, usually called a red and black (parallel) wire. It consists of two core wires in parallel, and the inner core wires are generally red and black, representing the positive and negative poles respectively.

RVB cables are widely used in home lighting, electrical appliances, instruments, radio and audio connection control, fire wires and other fields. Due to its softness and good conductivity, it is also suitable for wiring inside mechanical equipment.

The insulation material of RVB cable usually uses environmentally friendly PVC material, which is not only resistant to high and low temperatures (-20℃~+105℃), but also has good flame retardant and smoke-free properties to ensure safe use.

The conductor of RVB cable uses high-precision oxygen-free copper. This material has good conductivity and low resistivity, which can ensure the high efficiency and stability of current transmission and extend the service life of the cable.

RVB cable is a flat, unsheathed soft wire, while RVVB cable is a flat, sheathed soft wire, that is, RVVB has an extra sheath than RVB, providing additional protection.

The problems that RVB cable may encounter in use include leakage and short circuit caused by exposed copper core, limited service life due to general anti-oxidation ability, and weak anti-friction ability on the side. Therefore, pay attention to protection when wiring to avoid tearing.

The key to avoiding short circuit of RVB cable is to connect the wire correctly, ensure that the joints are firm and not loose, and regularly check whether the cable is damaged or aged. At the same time, avoid excessive bending or squeezing of cables during wiring.

To improve the antioxidant capacity of RVB cables, you can start with the selection of higher quality insulation materials and conductor materials. In addition, maintaining a good use environment and avoiding long-term exposure of cables to humid or high temperature environments can also help extend the service life of cables.

The repair and replacement of RVB cables are relatively simple, but due to their sheathless design, care should be taken to protect the copper core from damage during repair. When replacing, cables with the same specifications as the original cables should be selected to ensure electrical performance and safety.

The selection of the appropriate RVB cable length and specifications should be determined according to the specific application scenario and load requirements. Generally speaking, the cable length should leave an appropriate margin for easy wiring, and the specifications should be selected according to the current transmission requirements to ensure that the cable can withstand the working current and maintain stable electrical performance.
