Product Description
FLW series pole mounted sf6 load break switch is newly developed switch. It has compact structure, complete functions. It adopts sf6 as insulation medium, equipped with high precision CT, zero sequence CT and zero sequence PT. It can be used for load current and overload current in the medium voltage power distribution network breaking and making system. It can insulate the failed line section automatically.
Features:
1. High purity sf6 gas with good insulation and arc performance (above 99.9%) is filled in the switch body. Arc extinguishing time is ≤ 10ms (1/2 cycle). Good insulation recovery, low consumption in breaking part contacts, no need of maintenance and change in breaking part.
2. Switch body is made of 304 stainless steel, lifelong corrosion proof.
3. Spring charging operation mechanism, manual or motor open and close operation, quick close and open within 60 ms, work well with backup protection device.
4. Manual lock is equipped, preventing mal-operation during maintenance, increasing safety.
