RVV Wire Related Knowledge, RVV Is What Wire? Rvv Is What It Means?

Since I have not understood the professional knowledge of the wire, I occasionally see the layout of the wire when I find that the wire is marked with a lot of letters and numbers I do not understand what rvv is and what 2.5 and so on, both do not understand and will not.

I'm not sure what it means, but I don't know what RVV means. We don't know what 3*2.5 stands for, what 3 and 2.5 stands for, what 2*2.5 stands for and what it means. What does it mean between them?

What does RVV stand for?

RVV: a double-layer flexible polyvinyl chloride insulated sheath with multi-strand oxygen-free copper core soft wire.

3*2.5, 3 is for 3 oxygen-free copper core conductor wire, 2.5 represents the area of each copper core cross-section, is 2.5 mm square unit.

It is an abbreviation in English, and somewhat of an initial in Hanyu Pinyin.

R for "soft" initials "R", representing soft;

V in PVC stands for "V".

B actually stands for "hard", so the letter "B" in the wire represents a hard line.

K is the initial "K" for "control", representing the purpose of control.

Common electrical cables such as RVVB, BVVB, KVV, BV, BVR, etc. are used for the transmission of electrical energy. Telephone cables and super category 5 cables are communication products used for the transmission of signals.

So 3*2.5 and 2*2.5 of RVV both refer to laying a 3 core 2.5 square plus a 2 core 2.5 square RVV wire inside a PVC pipe. 3*2.5, representing 3 cores and 2.5 MM2 respectively. 25mm diameter plastic pipe, concealed.
