36kV Auto Recloser

Description

Rcw+ type 36kV auto recloser is ANSI/IEC standardized plus design products which is equipped with one magnetic actuator mechanism, one manual closing/opening/Locking device, 3 current sensors, max 6 voltage sensors, with more functional like protection curves, curves programble, coodination logics + logics  programble,  programble communication protocols, PC software, APP control tool, reclosing times setting support, dead time setting support, events recording functionswith fault record and normal operation recprd, etc.

---------------------------------------------------

Rcw+ type 36kV auto recloser is a solid insulation reclosure with zero pressure Sf6 GAS sealed. with high creepage design, higher insulation level.

It's vacuum interrupting technology, and IP67 IP protection class, It avoid any bad influence high polution enviroment of humidity, salt or alkali incursion or small animal,etc.

---------------------------------------------------

Rcw+ type 36kV auto recloser is proper for using in either important area or extreme bad envirment area which normal ACR is not capable well service!
