3.RVB-40.5 Spring type VCB main characteristics
| Reliable manual opening deviceReliable and labor-saving manual closingVisible sub-closing indicatorIP64 protection class plug connectorDescription: ROCKWIILL offer a unique design of the manual switch on technology to meet the state of conventional and unconventional features of the Closing. Its speed to meet IEC62271-100 and similar GB1984-2003 standard requirements. The emergence of the technology to make up for the permanent institutions and agencies in their respective spring shortcomings, is a new generation of high-performance power switching distinguishing features. Primary busbar terminal (direct overlap with the interrupter to reduce unnecessary power losses) Vacuum interrupter (APG process using solid-solid insulating sealing technology, plus silicone rubber molding compound technology to improve the overall switch weather performance) Extensible outlet pipe (plus modular design, which will help insulation margin of certainty and product interchangeability requirements) RVB series vacuum switch rejection of the traditional switch design concepts, will absorb some of the advanced design concepts, simplifying the overall transmission mode switch, greatly reducing the transmission power loss of this switch makes switching better overall performance and longer life. Makes the whole body switches provide a higher life expectancy, more stable mechanical properties. RVB-40.5N provide up to 25,000 times the mechanical operation of life, institutions 20,000 times the number of maintenance-free operation. RVB-40.5Mto provide up to 100,000 times the mechanical operation of life. |
