Through searching, most similar implementation is at present, the insulator crossarm and insulator made using hard insulation
Supporting rod is replaced, insulator crossarm principle is that three-phase conducting wire is placed in insulator crossarm, by lifting wire to certain altitude, then
Carry out the live line works such as cross-arm replacement, replacing insulator supporting rod, when being used for charged for replacement branch line pole insulator, by by conducting wire
It is placed in strut, then former insulator is replaced.
But the existing insulator crossarm made using hard insulation and replacing insulator supporting rod, in charged vertical
The reason of can not using well, lead to this disadvantage during bar is：(1) either insulator crossarm or supporting rod, all need
It is fixed on electric pole or aerial lift device with insulated arm, and charges newly vertical electric pole often between having adjacent two electric poles, so
It has no idea to be mounted on the enterprising row conductor support of existing electric pole；(2) existing insulator crossarm and supporting rod, effect is all only
It is to allow original conducting wire to be detached from supporting insulator, retighten in interim insulating supporting equipment, can not play to strut and lead
The effect of line, can not ensure to charge during upright bar that alternate there are enough spaces.
