The spring touches the connector It is used in GCB/GIS (enclosed combination electric) switchgear intermediate sliding contact, dynamic and static contact contact. High-performance conductive materials are selected. Manufactured by a special process. Suitable for compact electrical contact design of switchgear. Rely on the deformation of the ring spring made of conductive material to provide the contact pressure of the contact point to carry the rated current. Dynamic thermal stable current. Over a wide range of operating deformations, the pressure at the contact points remains almost constant. It can make up for the corresponding grooves, processing differences of conductive rods, roughness errors, etc. by itself. It can greatly reduce labor intensity and production costs. Simple structure, convenient assembly, strong flow ability, cost saving; Small size, multiple contact points, small heat accumulation, impact without electric spark, automatic arc extinguishing characteristics; Each coil works independently to straighten large contact tolerances and compensate for surface irregularities, effectively addressing resistance drift; It can maintain good performance in shock, vibration and harsh environments.
