With the continuous development of science and technology, all kinds of electrical equipment required in modern life are becoming more and more popular, and the normal operation of these equipment is inseparable from the bearing and transmission of the wire. Among these wires, RVSP wires and 485 communication lines are common types, and today we will learn about their differences and implementation standards.

What is RVSP Wire

RVSP wire model Structure combination: R - soft structure cable V - polyvinyl chloride plastic (PVC) S - twisted pair P - copper wire braid. Shielded twisted pair RVSP also called RVVSP shielded twisted pair cable structure: polyvinyl chloride insulated polyvinyl chloride sheathed twisted pair shielded cable, only suitable for general data transmission, transmission distance is relatively close. This wire is characterized by high softness, and soft texture, very easy to bend and twist, coupled with its soft skin, so it is very easy to install and use, but also very durable. In addition, RVSP wire heat resistance, wear resistance, corrosion resistance and other characteristics are also more prominent. When using this kind of wire, it is recommended to avoid long-term exposure to the sun, so as not to affect the service life of the wire.

What is a 485 communication cable

485 communication line, is a high-speed data transmission line, it can achieve data communication between multiple devices. This kind of wire is usually composed of A pair of twisted pairs, one of which is wire A and one is wire B. When transmitting data, the voltage signal of line A and line B will change back and forth, by changing the positive and negative voltage signal to achieve the transmission of 0 and 1. 485 communication line is characterized by fast transmission speed, low error rate, strong anti-electromagnetic interference ability, so it is widely used in industrial control, automated production and other fields.

Implementation standard for RVSP wires and 485 communication wires

From the implementation standard point of view, the implementation standard of RVSP wire is mainly GB/T5023-2008, which is applicable to the rated voltage of 450V/750V and below AC power supply, power tools, household appliances and other products internal wiring cables. The implementation standard of 485 communication line is mainly YD/T 1155-2001, which is suitable for the field of data communication and can achieve data transmission between multiple devices.

The difference between RVSP wire and 485 communication wire

In general, RVSP wires and 485 communication wires differ in usage scenarios and execution standards. For household appliances and low-voltage electrical equipment, the use of RVSP wire is more suitable, its high softness, easy installation, strong durability and other characteristics, can effectively meet the needs of daily use. For industrial control, automated production and other fields, the use of 485 communication lines can achieve high-speed data transmission, strong anti-interference ability and other characteristics, can better meet the needs of this field.
