Special Cable Solution for High-Voltage Transmission Networks Gwamnatin IEE-Business na Special Cable Solution don High-Voltage Transmission Networks

Scenarios na Application​
Upgrade na grid mai zurfi, kungiyar da takeke masu industrial parks, integration na renewable energy power stations, da kuma scenarios masu transmission da zama da karkashin ciki a wurare.

​Core Requirements​
Flame retardancy da yawa, structure mai kyau don installation, resistance mai yawa a kan corrosion, da kuma resistance mai yawa a kan mechanical stress.

​Solution​

• ​Material Upgrade:
  Amfani da cross-linked polyethylene (FL-XLPE) da yake samu flame-retardant a matsayin material da ake amfani da shi. Composite flame-retardant system na magnesium hydroxide/aluminum hydroxide ya ci rating mai flame retardancy wanda ta da IEC 60332-3 Class A standards.
• ​Structural Optimization:
• Conductor na high-conductivity copper alloy da design na segmental ya ci fill factor zuwa 93%.
• Three-layer co-extruded shielding structure (semiconductor shielding layer + insulation layer + semiconductor shielding layer) ta tabbatar da uniform electric field distribution.
• Metal shielding layer ta yi composite structure na copper wire braiding + galvanized steel tape armor.
• ​Protection System:
• Outer sheath na polyamide-polyurethane composite material, da chemical corrosion resistance ta ci ISO 6722 standards.
• Addition na carbon nanotube reinforcement layer don ci crush resistance (zai iya taka ≥20 kN/m pressure).

​Implementation Results​
Ba a gaba a kan project na coastal industrial park:

• Cable installation density ta zama zuwa 35%.
• Failure rate ta zama zuwa 0.12 instances/100 km·year.
• Expected service life ta zama zuwa 35 years.
• An pass electromagnetic compatibility tests a kan CISPR 22 standards.

​Smart Monitoring Expansion Function​
Distributed temperature sensing (DTS) da partial discharge monitoring modules za su iya zama optional, wanda ke maimakanta real-time operational status monitoring, ta haka za su iya ci warning accuracy rate da ≥90%.

​Note: Wannan solution ta ci standards kamar GB/T 12706-2020 da IEC 60502-2. Customized designs suna da kyau a kan specific engineering requirements.
