RVV wire and cable and RVVP Wire and cable In a literal sense, RVV refers to the unshielded sheathed power cord, and RVVP refers to the shielded sheathed power cord. P represents the meaning of shielding, that is, RVVP has a layer of shielding layer (aluminum foil + shielding network) than RVV, and the main effect is anti-interference (external signal interference).
1. Different definitions:
RVV cable full name copper core PVC insulated PVC sheathed flexible cable, also known as light PVC insulated polymer, commonly known as soft sheathed wire, is a kind of sheathed wire. RVV wire and cable is two or more RV lines with a sheath. RVV wire and cable is the most commonly used cable of weak current system, the number of core wires is variable, two or more, there is a PVC sheath outside, and the arrangement between the core wires is not special requirements. The letter R stands for flexible wire and the letter V stands for insulator polyvinyl chloride (PVC),
RVVP full name copper core PVC insulated PVC sheathed shielded flexible cable, R stands for flexible wire; V PVC insulation; V polyvinyl chloride sheath; P Mask. RVVP is a soft conductor PVC insulated wire with shielding layer and PVC sheathed cable, copper core PVC insulated shielding PVC sheathed flexible cable, also known as electrical connection anti-interference flexible cable. Rated voltage 300/300V.
2. Different uses
RVV wire and cable Main uses: used in electrical, instrumentation and electronic equipment and automation equipment with power lines, control lines and signal transmission lines, specifically can be used in anti-theft alarm system, building intercom system, home lighting connection line.
RVVP is suitable for communication, audio, broadcast, sound systems, anti-theft alarm systems, intelligent automation systems, automatic meter reading systems, fire protection systems and other anti-interference line connection, efficient and safe transmission data cables. The advantage of RVVP is to reduce the influence of external signal interference to a very low level.
3. Different colors
RVV is black and white. The RVVP is black.
Do you choose RVV wire and cable or RVVP wire and cable? It should be selected according to the performance of the wire and cable and the desired use.
The development of China's wire and cable industry began in the early 80s of last century, our country wire and cable industry really began to develop rapidly after reform and opening up. Back in 2006. China's cable production capacity is greater than 13 million kilometers, the steel core twisted wire weight is greater than 930,000 tons, and in recent years, China's wire and cable industry is developing rapidly, now, with the rapid development of various industries in China makes China's wire and cable industry scale is also expanding, The industrial structure continues to upgrade the production of China's wire and cable industry can basically meet the needs of the market, and even its production capacity has exceeded the market demand, and now China's wire and cable industry has jumped to the world in terms of the overall scale and growth rate.
Recycle wire and cable
In order to make certain achievements in the research work, I would like to extend my sincere thanks to the academic circle.
In addition, there are also house demolition cable recycling machinery, pile foundation pipe making machinery, device machinery, roof steel plate spraying machinery, cable combination device, etc., composed of civil construction and auxiliary construction. Among them: air compressor, motor combination, drilling machine, pumping unit and so on. Device machinery refers to the main engine and auxiliary machinery, the selection of cutting, winch, friction motor, compressed air machine and so on.
Moreover, the building energy saving changes with each passing day in our country, such as: household building heating, cold and hot water supply, the total amount of household copper cable opening is becoming more and more. The sound insulation of homes is getting better and better. Sound insulation board is a kind of special sound insulation material, so that cable sound insulation and sound insulation board combined, generally are the main components of sound insulation materials, the process is integrated, can achieve the same sound insulation effect of similar products, but also to achieve the purpose of the same product cost performance.
Today, we share three industries that meet the price of copper cable recycling: pure copper cable. Non-copper cable. More important metal cables, such as copper pipes, lead pipes, etc. When recycling, we should pay attention to the selection of cable suppliers, try to choose regular channels for acquisition, and guarantee the quality of low prices and high quality. Managers need to strictly adhere to environmental industry standards.
Operate according to classification by comparing manufacturing locations, etc. According to the composition of the pipe has no relation to recycling. The general cleaning solution at room temperature belongs to the cleaning solution at low temperature, and does not belong to other constituent substances.
There are two branches of domestic research, one is domestic import cable and foreign export cable; One is the domestic import of foreign cables.
5. Research on the application of optical cable recycling in 35KV lines, the project was established in September 2007 and jointly implemented, and was applied in the 35KV line from Qingyuan Baituan to Haozhuang Substation. The project was constructed at one time, which shortened the construction period, reduced the damage to farmland seedlings, enhanced the disaster prevention and resistance of optical fiber, and realized the integrated transmission of power flow, business flow and information flow. Second-hand cable recycling line recycling products purchase common sense is as follows:
View the CCC authentication identifier. Therefore, the cable recycling line products are mandatory safety certification products, wire and cable all manufacturers must obtain the electrical products certification will be certified "CCC" certification, "CCC" certification mark, in the certificate or product there is a "CCC" certification mark.
Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
