Product NamePRODUCT Name
60227 IEC 53 (RVV) type cable
Product ApplicationsPRODUCT APPLICATIONThe full name of the RVV cable is copper-core polyvinyl chloride (PVC)-insulated, PVC-sheathed flexible cable, also known as lightweight PVC-insulated PVC cable or, colloquially, "soft-sheath wire." It is a type of sheathed wire. An RVV wire and cable consists of two or more RV wires encased in an additional outer sheath. The RVV cable is the most commonly used cable in low-voltage systems; the number of core wires can vary—two or more—and it features an outer PVC sheath. There are no specific requirements for the arrangement of the core wires. The letter "R" stands for "flexible wire," and the letter "V" stands for the insulating material, polyvinyl chloride (PVC). This cable is suitable for control signal transmission lines, electrical equipment, instruments, automated devices, security and anti-theft alarm systems, intercom systems in high-rise buildings, and household lighting connection cables, among other applications.
Technical ParametersTechnical parameterRated voltage: 300/500V
Structure:
Conductor: Number of cores: 2, 3, 4, or 5 cores; the conductor complies with the requirements for Class 5 conductors specified in GB/T3956-1997.
Insulation:
The insulation extruded onto the conductor shall be a PVC/D-type polyvinyl chloride compound.
The insulation thickness shall comply with the specified values in Column 2 of the table below. The insulation resistance shall be no less than the specified values in Column 6 of the table below.
The insulated cores and any fillers (if present) are cabled together.
Round flexible wire: The insulated conductors and any filling (if present) shall be twisted together.
Flat cable: The insulated cores should be arranged in parallel.
For two-core round flexible cables, the gap between insulated cores may be filled individually or by the jacket; any filling material used should not adhere to the insulated cores.
Sheath:
The jacket extruded over the insulated conductor core shall be a PVC/ST5 type polyvinyl chloride compound.
The sheath thickness shall comply with the specified values in Column 3 of the table below.
The jacket shall allow filling the voids between the insulated cores to provide padding, but it must not cause the insulated cores to stick together. After the insulated cores are stranded into a cable, an isolation layer may be applied, but this layer also must not cause the insulated cores to stick together.
The finished circular soft wire should actually have a circular cross-section.Conductor nominal
