Reliability and Stability
Solid Insulated RMU is totally SF6 free, unlike SF6 RMU; the
insulation ability depends on the pressure level of SF6 gas.
Every phase is embedded within epoxy resin cast independently,
therefore, no potential risks of discharging between phases.
Product successfully passed the test by submersing the unit into
water under pressure of 0.3 bar for *4 hours’ live operation.
Epoxy resin cast tested before and after production, we ensure
the partially discharging for the cast is less than 5PC. Vacuum
interrupter adopts domestic well-known brands.
Switchgear cast successfully passed the thermal shock test to
ensure the cast not affected by severe temperature changes.
High glass transition temperature ensures the insulation ability
of cast and silicon rubber does not drop down under high
temperature.
