WDZ-RY 450/750V
Copper Core Low-Smoke, Halogen-Free, Cross-Linked Polyolefin Insulated Flexible Wire
Product Applications
Applicable to applications with AC rated voltages of 450/750V and below, such as subways, high-rise buildings, shopping malls, theaters, power stations, chemical plants,city squares, and other public utilities, where flame retardancy is a high requirement. The low corrosiveness of combustion gases also prevents damage to equipment. The low-smoke, halogen-free properties significantly enhance the cable material's resistance to aging, UV rays, and other radiation,
thus extending the cable's service life.
