Feature
The load break switch used is a separate unit, inside filled with SF6 has as insulation medium, wren aisunguisnea teachers of long service nte, sign parameters, tree of position and little maintenance;
The enclosure consists of premium Aluminum zinc-coated sheet steel, which makes it anti-corrosion, anti-oxidation, more artistic, and novel in structure;
Spring charging operation, three-phase tree trip, five-proot interlock, and operation meth animism as a whole, safe and reliable linkage;
The ring main unit can easily form a ring network power supply unit or other forms of wiring, and enjoy great extendibility;
SF6 load break switch is used with safe and reliable comprehensive properties, free of oil and poison as well as risks of explosion or fire disasters.
The design would be used as a combined cabinet along with KYNzB-iz(GZSI) central-in-stalled switchgear.
Teknik Parametreler
Compact design: Contain more function units with less space.
Strong versatility for structure, flexible assembly. C type bar section of 25mm modulus can meet the demands of various structures and types, protection grades and operating environments.
Adopt standard module design, can be combined into protection, operation, transfer, control, regulation, measurement, indication, etc such standard units. Users can choose assembly according to requirements at will. A cabinet structure and drawer unit can be formed with more than 200 components.
Fine security: Adopt high-strength antifoaming type engineering plastic pack in large quantities to effectively enhance the protective safety performance.
High technical performance: Main parameters reach the advanced level at home.
