B2 is by ice-melt wire and connects the folder that wire is separately mounted to be made up of the fluted body copper sheet of two pieces of porcelain blocks
Mouth two ends;
B3 is reduced the distance between described two pieces of porcelain blocks by tighting a bolt, and makes described ice-melt conductor and described company
Connect conductor reliably to electrically connect with described copper sheet;
In described step B2, wait to continue for two and can the positive pole of ice-melt conductor of optical fiber composite overhead ground wire capable of melting ice connect
Line group is along one end of a jaws axis direction jaws installed therein, and negative terminal group is installed along jaws axis direction
One end in another jaws.
10. method of attachment as claimed in claim 7, it is characterised in that:
When described can optical fiber composite overhead ground wire capable of melting ice need ice-melt when, open described ice-melt plant-grid connection room, pluck
Lower plug-in accesses the protective cover of terminal outer, accesses one end of stud and described plug-in in the hollow of terminal
Conductive layer is threaded;The positive and negative connector of plant-grid connection case is accessed described plug-in and accesses in terminal so that
The boss of described plug-in access terminal stretches in the shrinkage pool of described positive and negative connector;The other end by described stud
Threaded with the screwed hole bottom described shrinkage pool.
