Low-smoke, halogen-free (LSZH) is a material classification for wire sheathing in the wire and cable industry. LSZH wire sheathing is composed of thermoplastic or thermoset materials that emit low smoke when heated and are inherently halogen-free. The reference standard for LSZH is JB/T 10491-2004, and numerous domestic manufacturers have the capacity to produce it. Let's take a closer look at the features of the WDZ-BYJR.
What is the application range of the WDZ-BYJR LSZH flame-retardant flexible cable?
This product is intended for use in power equipment, household appliances, small power tools, instrumentation, and power and lighting circuits (fixed installation) with an AC rated voltage of 450/750V or less.
Implementation Standards
JB/T 10491-2004 "Cross-linked Polyolefin Insulated Wires and Cables, Rated Voltage 450/750V and Below"
GB/T 19666-2005 "General Rules for Flame-retardant and Fire-resistant Wires and Cables"

Special Features
Flame retardant, halogen-free, and low-smoke properties meet the requirements of GB/T 19666-2005.
This concludes our introduction to the WDZ-BYJR low-smoke, halogen-free, flame-retardant flexible cable. The cable's sheath is composed of polyethylene, polyvinyl chloride, or thermoplastic polyurethane. Chlorine-containing plastics release toxic hydrogen chloride in the event of a fire, which, when exposed to water, produces hydrochloric acid. The low-smoke, halogen-free material reduces the production of toxic and corrosive gases during combustion. Therefore, the WDZ-BYJR low-smoke, halogen-free, flame-retardant flexible cable is highly practical in everyday life.
