Contact spring produced by our company is made of imported and domestic high-performance excellent conductive material through special technology. It applies to switchgear compact electrical contact structural design. It depends on circular deformation of spring so as to provide contact pressure for loading of rated current, dynamic-thermal stability current. In a large range of working deformation, pressure of contact point can almost keep constant. It can compensate the corresponding groove, machining error of conducting rod, roughness error and etc. by itself. It is extensively used in intermediate sliding contact and dynamic and static contact of such device as GCB/GIS switch, cast pole, circuit breaker and etc. Characteristics: Simple structure, convenient installation, various contacts, good conductivity, high current capacity, high dynamic and thermal stability, even electrical field, large contact deformation range and fundamentally constant contact pressure, low wear, long service cycle and grooving size subject to machining, specification serialization, conducting rod of various diameters which could be offered as well as an extensive applicable range.
