Air Insulated Metal Clad Switchgear (AMC) 17.5 KV
General Description:
- Air-insulated Metal Clad (AMC) panels are type-tested,
air-insulated metal clad units that can be assembled
side-by-side. - The standardized AMC switchgear can be
configured according to customer requirements which
allows it to be functionally matched to its application. - Also,the panels can be extended at either side or modified later
after installation. - The AMC switchgear has separate compartments for
busbars, switchgear, cable connections and low voltage
equipment. - This ensures a high degree of reliability.
Main Features:
- High operating reliability
- Simple maintenance and inspection
- Internal arc tested (25kA-31.5kA 1s)
- Mechanical / electrical interlocks to prevent unsafe operations
- VCB, earthing switch position and voltage presence indicators
- Modular design extensible to both sides
- Easy frontal access to install and to test MV cables
- Use of highly recyclable materials
- Easy cable connection
- Possible to be connected with any SCADA system
Approval:
12KV AMC panel passed all necessary tests carried out in The Egyptian Electricity Authority Pyramids High Voltage Research Center and approved from The Egyptian Electricity Holding Company.
Standards:
The AMC is designed, manufactured and tested in conformity to the latest standards.
