II. Mada ya Teknolojia na Maana ya Utility Model
- Mada ya Teknolojia
Vito vya umeme na cables, kama bidhaa msingi za kutuma nguvu, kutuma taarifa, na kubadilisha electromagnetic energy, mara nyingi huandikwa kama "blood vessels" na "nerves" ya kiuchumi. Uaminifu wao unahusiana moja kwa moja na uendeshaji mzuri wa mifumo yote. Hata hivyo, cables za kiwango cha juu zinazopo kuna changamoto kubwa:
• Biological na Environmental Erosion: Zinaweza kupata upungufu kutokana na rodents, insects, au moisture, acids, alkalis, na viwango vingine vilivyoko nje, zinaweza kuwa sababu ya upungufu wa insulation, short circuits, au hatari za moto.
• Uharibifu wa Mecha: Kwenye mazingira kama installation pulling, wind, na jua, outer insulation layer inaweza kupungua na kujawa, ikipatafsiriwa kuwa core imekuwa exposed na kuongeza hatari za usalama.
• Shielding isiyofaniki: Electromagnetic shielding isiyofaniki inaweza kuwa sababu ya cables kukua kwenye interference au radiation za nje, inayohusisha ubora wa signal na stability ya kutuma. - Maana ya Utility Model

XLPE Inner Sheath Layer |
Cross-linked polyethylene (XLPE) |
9.9~10.3mm (10.1mm) |
Inner layer of dual protection. Provides excellent primary insulation, heat resistance, mechanical strength, and resistance to acids, alkalis, and oils. Ensures core safety even if the outer sheath is accidentally damaged. |
|
Binding Tape Layer |
High-performance flame-retardant tape |

|
Aluminum Foil Layer |
Aluminum foil (with adhesive backing) |
0.1~0.2mm (0.2mm) |
Key layer for composite shielding. Works synergistically with the tinned copper braid to significantly enhance shielding effectiveness. The adhesive layer (facing the XLPE outer sheath) ensures tight, gap-free adhesion. |

XLPE Outer Sheath Layer |
Cross-linked polyethylene (XLPE) |
13.9~14.5mm (14.2mm) |
Outer layer of dual protection. Serves as the first line of defense against external environments, forming a safety redundancy with the inner sheath. The outer surface provides a foundation for optimized structures. |
(II) Optional Optimized Structures (Configurable Based on Application Scenarios)
Kutokana na mazingira extreme au special, muundo wa optimized hapa zifuatazo zinaweza kuongezwa nje ya XLPE outer sheath:
- Axial Ribs:
- Structure: Axially extending ribs are provided on the outer sheath surface, with an embedded grounding wire inside.
- Function: One end of the grounding wire connects to the internal tinned copper braid, and the other end is reliably grounded, forming an efficient discharge path that greatly enhances shielding and anti-interference capabilities. The rib structure also increases the cable's tensile strength and reduces direct wear on the outer sheath.
- Annular Protuberances:
- Structure: Annular protuberances are spaced on the outer sheath surface, with embedded ferrite magnetic rings inside.
- Function: The ferrite rings effectively suppress high-frequency electromagnetic interference, further optimizing the shielding spectrum. The annular protuberances also provide compression resistance and reduce wear.
- Polyester Fiber Braided Layer:
- Structure: A high-strength polyester fiber braided net is applied as the outermost layer.
- Function: Provides comprehensive environmental protection, effectively resisting UV radiation, high temperatures, humidity, low temperatures, acidic/alkaline gases, and other erosive factors. It also mitigates mechanical impact, ensuring long-term safe operation in harsh environments.
IV. Advantages na Thamani za Teknolojia
- Dual Protection, Safe and Reliable:
- The dual-layer XLPE insulation design forms a redundant safety system. Even if the outer sheath is severely damaged accidentally, the inner sheath remains intact, significantly reducing the risk of power outages and short circuits and ensuring power supply continuity.
- Stable Structure, High Flame Retardancy:
- The compact binding tape layer ensures the structural integrity and stability of the cable, preventing internal loosening. Its high flame-retardant properties significantly enhance the product's fire safety rating.
- Efficient Composite Shielding, Excellent Anti-Interference Capability:
- The composite shielding structure formed by the tinned copper braid and aluminum foil layer ("metal braid + full coverage") provides 360° flawless shielding, effectively isolating internal and external electromagnetic interference. The optional grounding wire and ferrite rings can address interference issues in specific frequency bands.
- Exceptional Durability, Wide Application Range:
- Through the design of ribs and protuberances on the outer sheath and the outermost polyester braided layer, the cable's resistance to wear, tearing, and weathering is qualitatively leapfrogged. Its service life is significantly extended, making it suitable for a wide range of complex and harsh environments such as industrial parks, field installation, tunnels, and underground mines, reducing overall maintenance costs.
