Description:
The static contact is the key component of the high-voltage switch. The connection and disconnection of the high-voltage switch depend on it. Its service life determines the service life of the high-voltage switch, which in turn determines the safe operation of the high-voltage transmission and transformation grid. When the contact is working, it relies on its own rigidity to produce a pressing force on the moving contact. Therefore, the contact parts require high strength and rigidity in addition to higher electrical conductivity.
| Copper and aluminum combine products are new generations' products. |
| The tensile and bending strength of it are outstanding, and bonding performance is also good. |
| There are no surface cracks after flattening and bending, they are the domestic new type of energy saving products currently. |
| Dynamic thermal stability, temperature rise, and loop resistance are all compared favorably with the same levels of T2 copper, this is the idea products of the present electrical industry which can lower the costs. |
