- Hermetic Sealing All oil insulated Coupling Capacitors are Hermetically
Sealed against the outer atmosphere using a metallic
expansion bellow. This prevents absorption of
moisture by the active parts or the insulating oil.
- Mobile Base All type coupling capacitors are mounted on a mobile
base with swivel wheels allowing ease of transport.
Type CES 3-120, CES 3-150 have aluminium cast
flanges, CES 3-300 and above are provided with
suitably dimensioned aluminium to toroidal
electrodes for corona free operation up to rated
- Electrical Connections All types of coupling Capacitors are equipped with an
UHF coaxial socket for connection to the
Measurement Impedance. The neutral end of the
lowest capacitor stage is brought to this socket. The
measuring cable socket of the oil insulated
capacitors is protected against over voltage by gas
filled surge diverters.
When the measuring cable is removed, the
connection socket of all capacitor types must be
short circuited by a shorting Plug included in the
supply. Grounding screw on the base is provided for
connection of a ground lead.
