Product Description

FL(R)N36 Indoor AC High Voltage SF6 Load Break Switch and LBS-Fuse Combination are used for the three-phase AC 50/60Hz RMU and terminal power station. The switches are suitable for protecting the 10kV, 24kV and 35kV power system's on load situation. The switch can switch off the on load current, closed loop current, no load transformer capacity and cable charging current. The switch with fuse combination can cut off any current, when the current is in the range of the rated short-circuit breaking current. They are suitable for the RMU, combined transformer, etc..

FL(R)N36 of an indoor high-voltage SF6 load switch and FL(R)N36 load switch plus fuse combination are complied with the standards of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc..

Primary loop of FL(R)N36 indoor load break switch and its combination is sealed in a epikote casted insulate unit by APG technology, this insulate unit has features of good insulating property, dust and dust proof, insulate unit contains upper and lower insulate covers, inside charged 0.4bars pressure SF6 gas, the partial siding of lower cover is very thin, it's a protective measure and will burst out in the malfunction, the over pressed gas is released to protect the equipment.

SF6 load break switch and its fuse combination has open,close and earth three working position.
