Production Processes Of Electrical Cable
Our production relies on state-of-the-art manufacturing equipment to ensure superior cable performance. The process integrates precision copper drawing and annealing with advanced insulation extrusion technology for uniform thickness. Throughout production, strict quality control measures—including online spark testing and automated diameter monitoring—are applied to every meter. This rigorous workflow guarantees that our electrical cables meet stringent IEC and GB standards for residential and industrial use.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
Have more questions?
Q: Product Designation?
A: Harmonized Code (HD 361).
H07: Rated 450/750V (Mains Voltage).
V: PVC Insulation.
-U: Solid Conductor (Class 1). (Note: Commonly referred to as “BV Cable” in China or “Single Core Conduit Wire”).
Q: H07V-U (Solid) vs. H07V-R (Stranded)?
A: Rigidity & Size.
H07V-U: Solid (Class 1). High rigidity. Standard for sizes 1.5mm² to 10mm². Best for straight conduit runs.
H07V-R: Stranded Rigid (Class 2). Typically used for sizes ≥ 16mm² where solid cores become too stiff to handle.
Q: Primary Applications?
A: Mains Power Distribution.
Fixed Installation: Inside lighting fixtures, switchgear, and control panels.
Routing: Surface-mounted or embedded conduits/trunking.
Voltage: Suitable for 3-phase 415V motors and single-phase 230V circuits.
Q:Standards & Certification?
A: EU Compliance.
Standard: DIN VDE 0281-3 / IEC 60227-3.
CE: Low Voltage Directive 2014/35/EU.
RoHS: Directive 2011/65/EU.
Q:Temperature Limits?
A: Operational Specs.
Max Conductor Temp: +70°C.
Installation (Laying): +5°C to +70°C.
Short Circuit: +160°C (Max 5s).
Q:Outdoor Use?
A: No. Standard PVC is vulnerable to UV radiation and moisture. Must be installed inside UV-resistant conduits or watertight trunking if routing externally.
Q: Minimum Bending Radius?
A: Standard: 12D.
Q : Available Sizes?
A: Class 1 Range:
Standard: 1.5mm², 2.5mm², 4.0mm², 6.0mm², 10mm².
Note: For sizes >10mm², we supply H07V-R (Class 2) to ensure installability.
