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.
