1. Operation - The process of moving a moving contact from one position to another.
2. Split (gate) operation - the operation of switching the switch from the engaged position to the divided position.
3. Close (gate) operation - the operation of switching the switch from the sub-position to the co-location.
4. “Score†operation – after the switch is closed, the operation is performed immediately without any intentional delay.
5. Operation cycle - continuous operation from one position to another and back to the initial position; if there are multiple positions, all other positions are required.
6. Sequence of operations - a series of operations with defined time intervals and sequences.
7. Automatic reclosing (gate) operation - the sequence of operations that are automatically recombined after a predetermined time.
8. Close (on) - a combination of operations used to establish the energized state of the loop.
9. Break (break) - Used for the sub-operation of the loop when the power is on.
10. Automatic reclosing - automatic reclosing (gate) operation in the live state.
11. Opening and closing - the general term for breaking and closing.
12. Short-circuit breaking - breaking the short-circuit fault current.
13. Short circuit closing - the closing of the short circuit fault current.
14. Near-zone fault interrupt--breaking of short-circuit current in near-field fault.
15. Contact Opening Distance - The total clearance between the poles of a pole of a switch or any conductive part of the connection when sub-positioned.
16. Stroke? The distance between the starting position of the moving contact and the position of the switch.
17. Overtravel - the distance that the moving contact continues to move after the switch contacts contact during the closing operation.
18. Opening speed - the running speed of the moving contact during the switching (gate) process.
19. The distance between the contact and the static contact is the speed of the separation of the contact and the static contact.
20. Closing speed - the moving speed of the moving contact during the closing (gate) process.
21. Contact speed: The instantaneous speed of contact between the moving contact and the static contact during the closing (gate) process.
22. Breaking speed—The speed at which the moving contact moves during the opening of the switch.
23. Closing speed - the speed at which the contacts move during the breaking process.
We mainly produce EO and PO derivatives which can be used in Cement Additives, Concrete Admixtures. Important raw material for cement grinding aids and strength improvement agent, improve the Dispersion, reduce the the energy consumption of electric, save time and reduce the wear and tear of the machines. It can not only improve the early strength of cement, but also improve the late strength of cement.Our products for cement additives and concrete admixtures have been approved by so many International Multi-National Corporations such as SIKA, MAPEI, FOSROC, JIDONG, ect
