RLW &RCS-3N type medium-voltage pole mounted vacuum load break switch is a 3 phase full new design technology switch.I ts used on overhead distribution
lines as well as distribution substation applications for voltage classes 11kV up to 38kV. And its rated current can reach up to 1250A.
System solution for switching and sectionalizing line as well as automation and control systems,
e.g. in:
- Power plants
- Switching substations
- Companies in all industrial sectors
- Water treatment plants
- Office and administrative buildings
- Airports and logistic centres
- Oil/Gas plants
1. Standards and specifications:
Switchgear manufacture
The switchgear complies with the following specifications in accordance with relevant IEC publications: IEC62271-100/ GB1984-2003 or ANSI/IEEE C37.66
2. Operating conditions:
- Ambient temperature:
–Maximum +40℃, –Maximum 24 hour average +35℃
–Minimum (according to “minus 5 indoor class”) –40℃ - Humidity:
–Monthly average humidity 95%; Daily average humidity 90% . - Maximum site altitude: ≤ 3000 M above sea level.
- 3. Special operating conditions:
Special operating conditions are to be agreed on by the manufacturer and user.
The manufacturer must be consulted in advance about each special operating condition: - Site altitude over 1000 m:
–Allow for the reduction in the dielectric strength of the air.
- Increased ambient temperature:
–Current carrying capacity is reduced.
–Provide additional ventilation for heat dissipation. - Climate:
–Avoid the risk of corrosion or other damage in areas: - with high humidity and/or with major rapid temperature fluctuations.
– Implement preventive measures (e.g. electric heaters) to preclude condensation phenomena.
