We produce triple position switches for the DR-6 Ring Main Unit.
The triple position load-break switch (On/Off/Earth) was developed according to IEC standards. It ensures a natural interlock of the cubicle's primary functions. The arc extinction process is accelerated by the SF6 gas and due to optimized opening speeds of the mechanical drive. A patented arc extinction mechanism combines optimal revolution of the gas with perfect electrical contacts.
Mevoco's experience with the load-break switch RV44, used in SGC-SwitchGear Company NV's DF-2 range, is translated here into the RV50.
The RV50 load-break switch is classified as E3/M1 (100 cycles CO and 1,000 mechanical operations) according to IEC 62271-102 standards.
With a history dating back over 35 years, Mevoco nv has specialised, in particular, in the design and the production of medium voltage switches from 10 to 36 kV.
