RVV wire is generally known as sheathed power cord, is a soft sheathed wire, it is commonly used in weak current system cable, the number of core wires is variable, two or more, the outside is PVC sheathed, core wire arrangement and no special requirements. So what is an extruded RVV wire.

Extruded RVV wire refers to the RVV sheath is extruded by an extruded mold. Extruded cables are generally compact in structure, round in appearance, and not easy to damage. The disadvantage is that it consumes more sheath materials.

Ordinary RVV power cord is generally filled with filler inside the power supply, RVV power cord inside is with items such as nylon rope, this is the rope nylon products are mainly filled. However, the extruded RVV wire directly achieves the effect of tensile resistance in the process, and does not need to be filled, and the waterproof performance of the extruded RVV wire is also better. The price is relatively higher than the white empty tube type RVV wire.

RVV wire is mainly used in building intercom system, anti-theft alarm system, automatic control system, electrical equipment control internal line, electronic equipment and other transmission wire and cable. Simply put, doorbell intercom line.
