BVN

The many advantages of BVN type cables（THHN cable） are an important reason why they should replace BV type cables. However, BVN type cables have not been widely used in recent years, and the analysis is no more than the following reasons:

1. BVN products have not been well known to the people, the publicity of the relevant parties is not enough, and many advantages are not understood by many users.

2. Not long after the national BVN wire product standard was promulgated, the country has not included it as a mandatory standard.

3. Users have been accustomed to buying and using BV type wiring for a long time.

4. The cost of BVN is slightly higher than that of BV.
However, it can be expected that with the promulgation and implementation of the BVN-type product standard, this new type of product will soon be accepted by users. At present, some large buildings (such as the Olympic venues) in Beijing, Shanghai and other large cities require the use of fabric type BVN electrical cable. It is widely used in Europe, the United States, Canada and the Middle East. In foreign markets, this nylon covered BVN type wire occupies more than 95% of the cloth wire market. Although my country has just started, it has already given birth to a huge market.
