Graphic details
The spring finger is made of alloy copper wire with excellent elasticity and conductivity through professional process.It is applicable to compact electrical contact structure design of 10~1000KV power transmission and distribution equipment.It is widely used in sliding electric contact and dynamic static contact of high-voltage and ultra-high voltage GCB/GIS,medium voltage power distribution equipment,high-voltage gas insulated transmission line(GIL)and other equipment.
Characteristic
Simple structure,small size,convenient installation,many contact points,good electrical conductivity,large flow capacity,high electric and thermal stability,low wear,can meet the needs of more than 10000 operations,large contact deformation range and basically constant electrical contact performance.Therefore,the requirements for processing and assembly size tolerance of relevant parts are not high.In addition,the advantages of specification serialization,multiple diameter conductive poles and wide application range make the spring finger more and more popular with designers.
