AVVR wire and cable

The full name of AVVR cable is copper core PVC insulated PVC sheathed flexible cable for installation, which is a kind of sheathed cable. A represents cables for installation, the first V represents polyvinyl chloride (PVC) insulation, the second V - polyvinyl chloride (PVC) sheath, and R represents flexible structure wires and cables. It mainly refers to electronic cables with core conductor section of 0.4mm2 and below.

AVVR cable parameters

AVVR executive standard: JB8734-4-1998 sheath: PVC; Insulation: PVC conductor: multi-core bare copper wire, copper clad aluminum, etc. Rated voltage: 2271EC52 (300/300V) Working temperature: not more than 70 ℃ Line color: black and white Purpose: applicable to building intercom system, security monitoring and alarm system, internal wiring control wire of electrical appliances, computer, instrument and electronic equipment, automation device and other signal control wire. AVVR wire specifications: the common specifications of wire cores are 0.12mm2, 0.2 mm2, 0.3 mm2, 0.4 mm2, and the number of cores is 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. For example, AVVR3 * 0.2 wire means that the wire is composed of three strands, each with a specification of 0.2mm2.

AVVR cable product difference

1. Models with wire core more than 0.5 square meters (including 0.5) are classified as RVV; Below 0.5 is classified as AVVR, which is classified according to the industry executive standards, but the materials, processes, uses, etc. of the two are identical. RVV is a common PVC insulated PVC sheathed flexible wire, while AVVR is a light PVC insulated PVC sheathed flexible wire. 2. AVVR and RVV have two kinds of black extrusion and white empty tube (common, but also the manufacturer's white extrusion), and there are also fillers. The RVV filled with filler is generally filled with nylon rope products, and the main effect is tensile resistance. The black extrusion is to directly achieve the effect of tensile resistance in the process, (without adding filler), and the waterproof performance is good. The white air pipe type is directly added with a layer of PVC air pipe outside, which is generally waterproof, but the price is much cheaper, and is suitable for general use environment.

The difference between vvr and avvr

Although there is no obvious difference between wire VVR and AVVR in terms of model, there are substantial differences. VVR is a flexible cable, while AVVR is a light flexible cable. 1. Voltage difference: the rated AC voltage of VVR is 0.6/1KV, and the voltage grade of AVVR is 300/300V; 2. The executive standards are different: VVR manufacturing standard reference: GB/T 12706-2008, AVVR executive standard reference: JBB734-4-1998; 3. Different structures: VVR is a kind of power cable, like VV cable, AVVR is a kind of sheath cable, and A represents the cable for installation. 4. Different names: VVR is called copper core PVC insulated and sheathed flexible cable for short, and AVVR is called copper core PVC insulated and sheathed flexible wire for installation, commonly known as flexible wire. 5. Different uses: VVR is suitable for frequently moving power cords, such as computer power cords, etc. AVVR flexible cords are suitable for multi-core weak current security cables, and electrical equipment connection cables. 6. The number of cores is different: the conductor section of VVR cable is from 1.5-630mm2, the number of cable cores is 1-5, the conductor section of AVVR flexible wire is from 0.12-0.4mm2, and the number of wire cores can be up to 30. AVVR flexible cable model AVR copper core PVC insulated flexible cable for installation, AVRS copper core PVC insulated stranded flexible cable for installation, AVRB copper core PVC insulated flat flexible cable for installation.
