BVR and RV are soft wires, but the two are different specifications of wires, and small specifications of the line is difficult to identify with the naked eye, if you want to understand the relationship between BVR wire and RV, we should distinguish from what?

BV wire is a common wire material that is widely used in domestic, commercial and industrial fields. Identifying the voltage level of a BV wire is essential for electrician installation and maintenance. This article will introduce some quick ways to identify the voltage level of BV wire to help readers better understand and use this wire.

The installation and wiring of wire and cable is a very important link in electrical engineering, and the following aspects need to be paid attention to:

The cable for urban rail transit refers to the cable used in the urban rail transit system, mainly including power cable, communication cable, signal cable, etc. These cables play a vital role in the urban rail transit system, providing power and signal transmission for the operation of trains.

1, Use: This product is suitable for the fixed laying of power plants with rated AC voltage 450/750V and below.

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.
