2RLW12G/63020Fundamental swap with disconnector swap, ranking voltage 12kV and rated present 630A and brief circuit stand up to present20kA
3RLW-12G/630P20Fundamental swap with disconnector swap, ranking voltage 12kV and rated present 630A and brief circuit stand up to present 20kA. And with Present transformer 600/5A for relay safety.
Observe: Particular order or requirement can seek the advice of with Rockwill’s Engineer.
Common:
RLW &RCS-3N kind medium-voltage pole mounted vacuum load break swap is a three section full new design expertise swap.I ts used on overhead distribution.
strains in addition to distribution substation purposes for voltage courses 11kV as much as 38kV. And its rated present can attain as much as 1250A.
System resolution for switching and sectionalizing line in addition to automation and management techniques, e.g. in:
■ Energy vegetation
■ Switching substations
■ Firms in all industrial sectors
■ Water therapy vegetation
■ Workplace and administrative buildings
■ Airports and logistic centres
■ Oil/Gasoline vegetation
Requirements and specs:
Switchgear manufacture
The switchgear complies with the next specs in accordance with related IEC publications: IEC62271-100/ GB1984-2003 or ANSI/IEEE C37.66
Working situations:
• Ambient temperature:
–Most +40℃, –Most 24 hour common +35℃
–Minimal (in keeping with “minus 5 indoor class”) –40℃
• Humidity:
–Month-to-month common humidity 95%; Every day common humidity 90% .
• Most web site altitude: ≤ 3000 M above sea degree.
Particular working situations:
Particular working situations are to be agreed on by the producer and person.
The producer have to be consulted upfront about every particular working situation:
• Web site altitude over 1000 m:
–Enable for the discount within the dielectric energy of the air.
• Elevated ambient temperature:
–Present carrying capability is lowered.
–Present extra air flow for warmth dissipation.
• Local weather:
–Keep away from the chance of corrosion or different injury in areas:
• with excessive humidity and/or with main speedy temperature fluctuations.
– Implement preventive measures (e.g. electrical heaters) to preclude condensation phenomena.
