In the wire and cable industry, model designations provide essential information about the conductor material, insulation type, sheath type, and specific application characteristics. Understanding these codes helps in selecting the right product for electrical installations.
Before reviewing the models, here is a breakdown of what the letters commonly stand for:
-
B (First letter): "布" (Bù) – Wiring (for fixed installation).
-
B (Second letter): "玻" (Bō) – Fiberglass braided.
-
V (First letter): "聚" (Jù) – PVC (Polyvinyl Chloride) insulation.
-
V (Second letter): "护" (Hù) – PVC sheath.
-
L: "铝" (Lǚ) – Aluminum core (If absent, it indicates a Copper core).
-
F: "复" (Fù) – Composite / Neoprene (Chloroprene rubber).
-
R: "软" (Ruǎn) – Flexible wire/stranded conductor.
-
S: "双" (Shuāng) – Twisted (parallel or twisted pair).
-
X: "橡" (Xiàng) – Rubber insulation.
These wires utilize rubber as the insulating material, offering good flexibility and elasticity.
