Manufacturing Process Illustration

Material: High-purity copper conductor guarantees superior conductivity and mechanical flexibility.
Manufacturing: XLPE insulation is extruded via advanced cross-linking process (dry cure/CCV lines) ensuring insulation integrity even at elevated temperatures.
Armouring: Galvanized steel tape provides mechanical protection against crush and impact forces, and enhances rodent and termite resistance.
Sheathing: Flame-retardant, halogen-free outer sheath options meet strict environmental and fire safety standards (IEC 60332, 60754).
Testing: 100% routine high-voltage, insulation resistance, and partial discharge tests (in accordance with IEC and ISO).
Service Life: Designed for 30+ years under nominal operating conditions (Ref: Industry forum discussions).

Advantages & Technology Highlights

XLPE Insulation: Cross-linked polyethylene boasts a dielectric strength of 20–30 kV/mm, significantly outperforming traditional PVC. This results in higher allowed operating temperatures (90°C normal, 250°C short-circuit) and extended aging resistance.
Cu Conductors: IEC 60228 Class 2 stranded copper ensures optimal flexibility, reducing installation fatigue, and maintains low electrical losses (1.72 μΩ⋅cm resistance).
Steel Tape Armouring: Double steel tape delivers +400% enhanced mechanical protection compared to unarmoured cables, per VDE 0276 testing data.
Environmental Resistance: Outer sheath options include LSZH (low smoke zero halogen) complying with IEC 60754, critical for tunnel, metro, and public infrastructure.
Custom Multi-core Configurations: Tailored solutions for complex distribution, from 2 to 5 core arrangements, supporting system reliability in industrial networks.
Stringent Testing: Each drum passes partial discharge (<2pc at rated voltage), insulation resistance, and spark tests per IEC 60502-2 and ISO 9001 QA protocols.
