And customer technical specification
| Conductor || Adopting copper or aluminum, it depends on economic consideration. |
Tightly compressed conductor with good roundness and smooth surface.
Those above 800mm2 adopt five sectors design to reduce skin effect and neighboring effect.
Semi-conductive wrapping tape is to prevent penetration from inner screen to conductor and improve smoothness of inner screen.
| Inner/Outer screen || All adopt imported super-smooth cross-linked polyethylene screen material. The surface shall be smooth and electric field shall uniformly distribute. |
| Insulation || Adopt imported super-smooth cross-linked polyethylene insulation material. |
Extruded with inner and outer screens together, compactly combined.
Using gravity feeding to prevent external influences and ensure purity of raw material.
Advanced process expels internal stress of insulation. High roundness and small eccentricity.
| Water buffer layer || High-performance water-blocking material ensures better water blocking property of cables. |
Buffer layer design ensures enough expansion space for insulation.
| Metallic screen || Meets the requirement of metallic screen and system short-circuit capacity. |
Radial waterproof corrugated aluminum sleeve has excellent mechanical strength to protect insulated cores of cable.
Or, adopt copper wire screen.
| Bitumen || Anti-corrosion asphalt can effectively protect aluminum sleeve. |
| Over sheath || Extruded PE or PVC material |
Optional low smoke low halogen and low smoke zero halogen material
Optional flame retardant, termite prevention materials, to meet the need in different occasions.
| Semi-conductive layer || Continuous, bright graphite coating, as the electrode of outer sheath for voltage test. |
Optional extruded semi-conductive layer.
