Specification :

The high-pressured bus bar rabbet is the new bus bar channel which Our company and the domestic many scientific research institution develops together. Is suitable in exchanges 50~60hz, voltage 3.6kv, nominal current 400~6300a power supply system. major technique parameter 1) dielectric resistance: Each section of bus bar rabbet unit insulation resistance value should be bigger than or be equal to 1000m¦Ø2500v the megameter). 2) dielectrical strength: Before each section of bus bar rabbet leaving the plant, undergoes 1 minute power frequency compression test, the power frequency pressure resistance and the lightning surge pressure resistance value. 3) earth system: Meets the iec364-5-54 docking system's requirement. 4) protects the rank: Indoors: ip40; Outdoors: ip43, ip54. 5) load performance: Under the nominal current, the outer covering temperature rise conforms to gb763-90 "Time AC high voltage Electric appliance Long lasting work To give off heat" the standard request. 6) short-circuits the performance: Moves the heat-stable experiment to conform to gb2706-89 "AC high voltage Electric appliance To move Thermally stable Testing method" the standard request. The bus bar rabbet widely applies in the power plant, places and so on Industrial and mining establishment takes the generator and the main transformer, the transformer and the high-pressured power distribution cabinet as well as the high pressure unit during main return route's electrical connection. The goods supply length according to the 2m/festival establishment, the single-node length is not bigger than 3m generally.
