Following the preparatory work should be completed before the start of the accessory installation

　　After the 1 cable laying, cable laying installation see "instruction" and "use" of the cable tray

　　2 cable outer sheath insulation resistance test

　　A. before laying the cable, insulation resistance test.

　　B. Cable laying is completed, the insulation resistance test.

　　3 outdoor terminal ready:

　　A. basic frame size, "110KV, 220KV outdoor terminal shed scaffold size requirements" has been the size of the hole, can be made into a circular, the minimum diameter is Y

　　B. cable should be kept upright to the base frame, steel frame; from the datum level, 110KV cable should be at least 3 meters in length, 220KV cable should set aside at least 5 meters in length (some outdoor terminal specifications may be slightly longer, please consult the field engineer or direct contact with the dawn of the cable companies); if traction head, consideration should be given to remove the traction deformation length.

　　According to the "C. 110KV, 220KV outdoor terminal shed size requirements of" scaffolding erection work shed.

　　D. cable steel should be used at cable clamp used for fixing and supporting cables, the fixture can refer to "110KV, 220KV XLPE cable joint is fixed position and construction of length"

　　E. check phase

　　4.GIS terminal or terminal for transformer

　　GIS terminal or terminal for transformer

　　A.GIS combination electric appliance or transformer should have done electrical experiment.

　　B. phase has been approved.

　　The C. cable is laid in cable interlayer

　　D. should be free to leave enough length of cable, length according to the method considering the 110KV cable to the GIS silo bottom surface +2 meters in length, the 110KV cable to the GIS silo bottom surface +3 meters in length (in the case of traction, consideration should be given to consider removing traction deformation length.)

　　After the e.GIS cable terminal transformer terminal and wear to the bin body, can refer to "110KV, 220KV XLPE cable joint is fixed position and construction of" fixed length of cable.

　　GIS terminal or terminal installed after the completion of the transformer is ready

　　F. in the day of the cable terminal in cabinet, transformer factory technical personnel GIS/ should be removed insulating oil / gas.

　　G.GIS/ transformer manufacturers should be prepared to seal gasket and bolt.

　　H. welding of steel bracing, prepare cable clamp.

　　5 preparations of intermediate joint

　　A. cables shall be laid in place

　　B. is at the center of each intermediate connector, cable should be at least 1 meters (in the case of staggered traction, consideration should be given to consider removing the traction deformation length.)

　　C. check phase

　　According to the "D. 110KV, 220KV joints and scaffolding erection work shed shed requirements".

　　E. should be prepared to prevent ground water or rain water pump into the streets well.

　　6 before installation accessories, but also need some equipment

　　A.220v or 380V power supply, the power of at least 5KW

　　B. control tool and field, and 2-3 with the personnel on duty

　　The transportation and transition of C. tools and accessories

　　D. industrial anhydrous alcohol, the purity was 9909%, 1-1.5 bottle of /3 terminal.

　　E. liquefied petroleum gas bottle (2 replacement if necessary)

　　Some (group 1KG/, F. were increased when necessary)
