The meaning represented by letters

The letter R represents a flexible cord

The letter V represents insulation polyvinyl chloride (PVC)

RVV wire is a commonly used cable in weak current systems, with an indefinite number of core wires, two or more, and an outer PVC sheath. There are no special requirements for the arrangement of core wires.

The function of the protective sheath

For example, rvv2 * 0.5 refers to two wires with an area of 0.5 square millimeters and an outer sheath. The purpose of the sheath is to

1. Protect the inner protective layer of the cable from mechanical damage and chemical corrosion;

2. Enhance the mechanical strength of the cable.

Inspection requirements

RVV refers to multi strand copper core flexible wire, which looks like the markings on the wire and the thickness of the skin compared to the core The cortex is usually made of polyvinyl chloride material The copper core is twisted into 19 strands The specifications generally include 1, 1.5, and 2.5 square millimeters When looking at the length of the line (100 meters per circle), the national standard line is 95-100 meters, and the non-standard line is about 90 meters.

Due to the current home decoration, wire conduits are generally used, and then three copper wires (live wire, neutral wire, and grounding wire) are laid through the conduit. But sheathed wires are much safer than ordinary wires, so they are still commonly used in home decoration in the construction industry. Sheath wire refers to the power cord used in the past. In the past, for home decoration, sheathed wires were used as lighting and power cords; It can be directly buried in the wall or fixed on the wall. Its advantage is that it can eliminate the need for conduit or trunking, and is replaced by an outer protective insulation layer. It is easy, fast, visually appealing, and safe to use, making it a home choice for connecting household mobile plug boards, refrigerators, air conditioners, and other appliances.

classification

Sheath wires can be divided into soft sheath (rvv) and hard sheath (bvv)Supply of sheath wire RVV RVVP RVVB models complete in Tianjin

Specification Model

Sheath wire model:

The commonly used copper sheathed wires include: bvv, bvvb, rvv, rvVB, as well as aluminum sheathed wires blvv, blvvb

Sheath wires can be divided into two types: hard sheathed wires (BVV, BVVB, BLVV, BLVV) and soft sheathed wires (RVV, RVVB). According to their application environment and shape, they can also be divided into round sheathed wires and flat sheathed wires. Round sheathed wires are generally multi-core, while flat sheathed wires are generally single core.
