High-performance flame-retardant copper-core Class B PVC-insulated cable, ZB-BV, 4 mm²

Specializing in the production of premium-grade pure copper conductors with excellent oxidation resistance and low impedance; utilizing advanced insulation materials such as virgin polyethylene and expanded polyethylene for stable characteristic impedance, along with eco-friendly PVC jackets that offer superior aging resistance and exceptional flexibility. We also employ rigorous multi-stage testing throughout the manufacturing process to ensure top-quality CAT5e, CAT6, CAT6A, CAT7, and CAT8 network cables, as well as flame-retardant and low-smoke, halogen-free insulated cables—perfect for residential wiring applications.

Multiple checks, quality assurance

Zhuosheng Cables strictly adheres to national standards, conducting multiple rounds of rigorous testing to ensure that every meter of cable fully meets the required specifications.
The testing process includes: visual inspection, conductor cross-sectional area check, lay length measurement, insulation thickness measurement, print abrasion testing, voltage and resistance tests, Fluke network cable transmission performance testing, as well as aging, low-temperature, thermal shock, and flame-retardance tests.
