Nowadays, people are increasingly concerned about environmental protection, safety, and energy conservation. Choosing the right electrical wiring for home decoration is also a concern for many. So, what kind of electrical wiring is energy-saving and environmentally friendly? What kind of electrical wiring is safe and durable? What do the various letters on electrical wiring mean? For example, what do WDZB-BYJ cables mean? I imagine many of you have seen them but don't know what they mean, so today I'll share some information.
What does WDZB-BYJ cable mean?
W (Halogen-Free) D (Low Smoke) Z (Flame Retardant) B-Class - YJ (Cross-Linked Polyethylene) Y (Polyolefin)
W (Halogen-Free) D (Low Smoke): Halogen-Free, Low Smoke (commonly known as LSZH)
WDZB-YJY --- Low Smoke, Halogen-Free, Class B Flame Retardant - Cross-Linked Polyethylene Insulated, Polyolefin Sheathed Power Cable
WDZBN-YJY --- Low Smoke, Halogen-Free, Class B Flame Retardant, Fire-Resistant - Cross-Linked Polyethylene Insulated, Polyolefin Sheathed Power Cable
WDZC-BYJ --- Low Smoke, Halogen-Free, Class C Flame Retardant - Copper Core, Cross-Linked Polyethylene Insulated Cable Cable
If F is present: WDZC-BYJ(F) --- Low-smoke, halogen-free, Class C flame-retardant --- Copper core irradiated cross-linked polyethylene insulated wire
WDZB-YJY --- Copper core halogen-free, low-smoke, Class B flame-retardant, cross-linked polyethylene insulated power cable
WDZBN-YJY --- Copper core halogen-free, low-smoke, Class B flame-retardant, fire-resistant cross-linked polyethylene insulated power cable
WDZC-BYJ --- Copper core halogen-free, low-smoke, Class C flame-retardant, cross-linked polyethylene insulated wire
What is the difference between WDZB-BYJ and WDZC-BYJ?
The difference between WDZB-BYJ and BJY is that the former is a halogen-free, low-smoke, flame-retardant (flame retardant Class B) copper core cross-linked polyethylene insulated wire. It is made of a rubber compound that is free of halogens (F, Cl, Br, I, At) and environmentally friendly substances such as lead, cadmium, chromium, and mercury, and does not emit toxic fumes when burned. The latter is standard BYJ copper-core cross-linked polyethylene insulated wire, which emits toxic and unpleasant fumes when burned.
WDZB-BYJ offers greater reliability: High Strength: The wire insulation is rigid and mechanically strong, preventing mechanical damage during conduit insertion and preventing short circuits and leakage. It's easier to thread than standard BV cables and boasts a 50-year service life.
More Energy-Efficient: Low loss. The core is entirely made of 1# copper, with a copper content exceeding 99.95%, ensuring minimal wire loss and energy savings. The cost of the wire can be recouped in three years.
More Environmentally Friendly: Compliant with the RoHS Directive and meeting the latest EU Reach standards, it contains no heavy metals such as lead, barium, and chromium, ensuring no pollution to the environment or users. Unlike standard BV cables, WDZB-BYJ cables are non-volatile. The insulation layer does not contain oily plasticizers, eliminating the release of harmful small molecules, effectively preventing indoor air pollution.
The above is the explanation of the knowledge about WDZB-BYJ wires. WDZB-BYJ wires have many superior properties. The most obvious one is that the wire insulation hardness is high, the mechanical strength is good, the energy saving loss is small, and it is more environmentally friendly. Therefore, it is deeply favored by many construction and decoration personnel and is widely used in home decoration, shopping malls, office buildings, schools, high-rise buildings and other important places.
