Primary circuit loop of load break switch

Primary loop of FLBS 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 dirts proof, insulate unit contains upper and lower insulatecovers, inside charged 0.4bars pressure SF6 gas, the partial siding of lower cover is very thin, it's a protective measure and will burstout 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.
