Overview: This document provides technical specifications for three types of electrical switches: Vertical Break Switch, Center Break Switch, and Double End Break Switch, covering voltage ranges from 38kV to 800kV. Each switch type is detailed with electrical and mechanical parameters.
1. Vertical Break Switch (123kV-550kV):
- Electrical Parameters: Rated voltages range from 123kV to 550kV, with a consistent rated frequency of 60Hz. Continuous current ratings vary from 2500A to 5000A. Short circuit breaking current is 50kA for lower voltages and 63kA for higher voltages. The peak withstand current ranges from 130kA to 164kA.
- Mechanical Parameters: All models offer motor/manual operation with a mechanical endurance of 10,000 operations. Open and close times are specified, with weights ranging from 1050kg to 5820kg.
2. Center Break Switch (38kV-550kV):
- Electrical Parameters: Rated voltages range from 38kV to 550kV, with a rated frequency of 60Hz. Continuous current ratings are mostly 4000A, with some models at 5000A. Short circuit breaking current is 50kA for lower voltages and 63kA for higher voltages. Peak withstand current is consistent at 130kA to 164kA.
- Mechanical Parameters: Similar to the Vertical Break Switch, these models also offer motor/manual operation with a mechanical endurance of 10,000 operations. Open and close times are specified, with weights ranging from 590kg to 5060kg.
3. Double End Break Switch (38kV-800kV):
- Electrical Parameters: Rated voltages range from 38kV to 800kV, with a rated frequency of 60Hz. Continuous current ratings vary from 4000A to 5000A. Short circuit breaking current is 50kA for lower voltages and 63kA for higher voltages. Peak withstand current ranges from 130kA to 164kA.
- Mechanical Parameters: These models also offer motor/manual operation with a mechanical endurance of 10,000 operations. Open and close times are specified, with weights ranging from 650kg to 17450kg.
Standards and Lead Times: All products adhere to IEEE/ANSI and CSA standards. Lead times vary from 13 to 25 weeks depending on the model and voltage rating.
