TYPE EC
The EC range of capacitors are similar in design to the ET
range but are housed in a more robust container. They are
manufactured using a mixed dielectric material that consists
of polyester/polypropylene film and capacitor tissue. They
are impregnated and filled with a mineral oil. The container
is a Synthetic Resin Bonded Paper (SRBP) tube sealed at
both ends with resin assuring a hermetic seal. The
capacitors may be used in air, oil or SF6. They are
terminated with M6 studs x 15 mm long or tinned copper
wire.
