RVV and RVVP power cords are generally black extruded power cords, usually made of extruded moulds, and the filler is directly vacuum-filled with PVC material, compact structure, round appearance, and the outer sheath will be relatively Thick, wear-resistant, tensile and compressive properties.
RVV is mainly used for building intercom systems, monitoring dedicated power lines, etc.; RVVP is used for places with strong interference, such as communication, audio, broadcasting, etc.
The RVVP power cord refers to the power cord with a shielding layer, and the RVV power cord refers to the power cord with an unshielded inner layer.
The full name of RVV is copper core PVC insulated PVC sheathed flexible wire, also known as light PVC sheathed flexible wire, usually called soft sheathed wire, which is a kind of sheathed wire; rated voltage 300V / 500V , There are national standards between 2 cores and 24 cores, and more than two cores are twisted into cables (including ordinary type, flame-retardant type, low-smoke halogen-free type, fire-resistant type, and cross-linked type).
The internal conductor of RVV is composed of multi-strand copper cores. The number of core wires is uncertain. Two or more RV wires are added with a layer of PVC sheath. There are many types of inner wire core specifications, not only 2 cores but also 3 cores. 4 cores, 5 cores, 6 cores, etc. General specifications have 2-core power cords (2*0.5/2*0.75/2*1.0 etc.), 3-core power cords (3*0.5/3*0.75/3*1.0, etc.), 4-core power cords (4*0.5/ 4*0.75/4*1.0, etc.), 5-core power cord, 6-core power cord, etc.
RVVP full name RVVP full name copper core PVC insulated shielding PVC sheathed soft power cord, also known as electrical connection anti-interference soft cable, rated voltage 300 / 300V, common core number 2-24 cores (including general type, resistance Combustible type, fire-resistant type, low-smoke halogen-free type, cross-linked type).
There will be a layer of aluminum foil and metal mesh in the RVVP power cord. The tinned copper mesh is the best of the metal mesh, which can mainly minimize the influence of external signal interference.
RVV is suitable for power lines, control lines and signal lines, etc., generally household appliances, small electric tools, instruments, meters and automation devices. And RVVP is suitable for anti-interference line shielded wire and cable, such as communication, audio. Broadcasting sound system, computer, instrument and electronic equipment and automation device, etc.
