Deskripsyon
Isipioneer sa sektor sa eco-friendly switchgear sa Tsina, nag-espesyalize mi sa R&D ug pagbuhat og SF₆-free switchgear samtang dekada. Pinaagi sa atong core technologies, natukod nami ang industry standards. Naglangkob usab kami og fully independent end-to-end production chain, uban ang aming nahimo nga product matrix sa zero-emission ug high-reliability eco-friendly switchgear, gihatagan kami og trusted choice para sa power grid construction.
Ang 34.5kV 35kV 36kV 38kV Maintenance-Free Gas-Insulated Switchgear (GIS) mao ang high-performance medium-voltage power distribution core device nga gi-customize alang sa modern smart grids ug industrial power systems. Ini nag-integrate sa maintenance-free design, advanced gas insulation technology, ug stable power supply capabilities—addressing ang mga pain points sa frequent maintenance, environmental adaptability, ug operational stability sa tradisyonal nga 35kV switchgear.
Pinaagi sa pag-adopt sa low-global-warming-potential (Low-GWP) eco-friendly insulating gas ug hermetic stainless-steel gas chambers, wala na ang panginahanglan sa regular gas replenishment o component disassembly inspection. Isip critical unit sa 35kV power transmission ug distribution networks, gamiton kini sa urban substations, industrial parks, new energy projects ( sama sa wind ug solar farms), ug large-scale commercial complexes. Ini nag-siguro sa continuous, reliable power supply para sa high-demand scenarios, samantalang aligned sa global energy conservation ug emission reduction goals, gihatagan kini og sustainable solution para sa long-term grid operation.
Feature
35kV-Level Maintenance-Free Operation：Ang hermetic gas chamber (uban leak rate ≤ 0.1%/year) ug wear-resistant mechanical components nag-eliminate sa routine maintenance tasks sama sa gas refilling ug part replacement. Ini nag-reduce sa operation ug maintenance (O&M) costs ngadto sa over 60% kon makumpara sa tradisyonal nga switchgear.
Superior Stable Power Supply Performance：Equipado niini sa vacuum interrupters para sa arc extinction ug high-precision current/voltage transformers, ini nag-epektibo nga resist sa short-circuits, overvoltage, ug voltage fluctuations. Ini nag-maintain sa power supply reliability rate nga ≥ 99.98% padayon sa harsh environments (e.g., high humidity, dust, o extreme temperatures).
Eco-Friendly & Safe Gas Insulation：Gisulti ang Low-GWP environmental protection gas (compliant sa IEC 61730 standards) aron ma-avoid ang greenhouse gas emissions; ang fully sealed structure nag-prevent sa gas leakage ug nag-siguro sa personnel safety. Ini usab may strong corrosion ug pollution resistance, suitable sa indoor ug outdoor installations.
Compact Design & Smart Integration：Ang modular ug compact structure nag-save sa 40% sa installation space kon makumpara sa air-insulated switchgear, fit sa narrow areas sama sa urban underground substations. Ini nag-support sa integration sa intelligent monitoring systems aron trackon ang gas pressure, temperature, ug operating status sa real time, enabling predictive fault management.
