GW5 series improving type disconnect switch is double column horizontal rotary 50Hz three phase alternating current outdoor hight-voltage equipment,for hegh-voltage lines interchanging at load-free and also for electrical isolation between high-voltage lines and high-voltage electrical equipment,such as the maintained high-voltage bus-bar and circuit breaker.
It can be divided into ungrounded,single ground and double ground according to whether or not having the earth switch.
Type of earth switch:I type and II type.The moving stability of the II type is the same as the disconnect switch.
1.Contact finger is made of the new material which with high-strength,high conductivity and high flexibility,Rely on itself elastic force to clamp the contactor,so it avoids the vicious circle which caused by the corrosion of the spring,annealing and febrile,such as the clamping force to reduce,the contact resistance to increase and the cantactor radiation.
2.Using the fixed soft connection flow between the connector base and connection terminal,and in the both ends of the terminals.
Using insulating sleeve ,to ensure that the flow of reliable,flexible rotation.
3.All-sealed bearing,the bearing surface to meet the amount of molybdenum disulfide lithium base grease to emsure a reliable long-term rotation.
4.When 180 degree transmission,it canceled the complicated transmission box,it is repplaced by the simple and reliable mechnical one,to be sure of reliable action,anti-corrosion ability.
