General
GW25 outdoor high voltage disonnector switch has a double-column , horizontal , central, interruption structure,It is an equipment used for 50/60Hz three phase AC ,outdoor high voltage transmission and distribution system to switch and disconnect the circuit.
For this type disonnector switch, part of terminal is in contractless condition with the flexible conductor ,leading to a stable and reliable electricity performance.And the contact part adapt a safe and flxed device,so that contact and finger will not be separated by external force(like Strong Wind, Earthquake, Electric Power,etc.) when the disonnector switch in the close statement.
The base part adapt a multi-bearing structure to make the switch can operate flexibly in a long-term. Meanwhile, interphase drag rod and vertical link rod can adjust within ±20mm when in site installation. Because vertical link rod rotates 190°when disconnector is operated by operating mechanism, and then it constitutes a 5°dead-point structure at the open and close critical position ,so that make the switch cannot open and close automatically even under the external force.
Disconnector body can be equipped with grounding switch,which contain a mechanism can rotates 90°around its own long axis,so that the switch can operate flexibly.
When grounding switch close, it cannot happen contact separation even under the external force, also can bear the dynamic, thermally stable current same with the disconnecting switch.
Grounding switch and disconnecting switch with reliable mechanical interlock device,
Grounding switch also can like disconnecting switch to operate by the operating mechanism, otherwise,manual mechanism and motor mechanism can interchange.
