Technical Features of Common Chinese Building Wires
Several types of building wire in China serve the same purpose as Romex. These cables often use different insulation and sheathing materials, resulting in varying performance characteristics. The choice depends on the specific application’s voltage, temperature requirements, and safety regulations. Discussions on Chinese NM cables can be found on forums such as InterNACHI®️ (forum.nachi.org). Let’s compare some key features:
| Feature | PVC Insulated Cable (e.g., BV, BVR) | XLPE Insulated Cable (e.g., YJV) | LSZH Cable |
|---|---|---|---|
| Insulation Material | Polyvinyl Chloride (PVC) | Cross-linked Polyethylene (XLPE) | Low Smoke Zero Halogen (LSZH) |
| Temperature Rating | Typically lower | Higher | Higher, often with improved fire safety |
| Flame Retardancy | Varies, often flame-retardant | Often flame-retardant | Excellent flame retardancy and low smoke emission |
| Flexibility | More flexible | Less flexible | Moderate flexibility |
| Cost | Generally lower | Generally higher | Highest |
| Applications | General building wiring | Power distribution, higher voltage | High-safety environments, public buildings |
Himake International Industry Limited (www.himakecable.com) offers a broad selection of these wire types. Choosing the right cable ensures compliance with local safety regulations and optimal performance.
Different Types of Building Wires in China
