Insulated glass fibre reinforced plastic crossbar 1 is provided with three holes 1.2 and is spirally connected for spark gap 2；It is provided with a hole 1.4 for grounding lead rod 7
It is spirally connected；If four holes 1.3 are assembled for glass reinforced plastic sleeve, four sleeve pipes form two kinds of pitch-rows, can be suitable for the installation of differing heights, and
Cross-arm installation strength can be greatly increased, again can positioning both ground connecting rod 5；Assembling end cap 9 at two ends 1.1, it 9.1 is a muscle, energy
Stoping ground connection connecting rod to be moved rearwards by, in two end caps, wall energy stops ground connection connecting rod left and right play, and this structure is attractive in appearance, safe and reliable.
On ground connection connecting rod 5, contractive pressure fastens four rectangle joints 6, (Figure 14), and ground connection connecting rod is arranged on cross-arm inner chamber, and by
Sleeve pipe and end cap location, its manufacturing process is simple, easy for installation, compact conformation；Wherein three rectangle joints are spirally connected for spark gap,
One rectangle joint is spirally connected for drawing screw rod 7.
Briquetting 10 with constitute a penetrating cable clamp containing tooth briquetting 11, be suitable for insulated conductor 240mm2And following plurality of specifications is exhausted
Edge wire, its ratchet can pierce through insulating barrier and obtain energising；It is spirally connected with earth brace 13 containing tooth briquetting 11, earth brace guard shield 14 and ground connection
Bar 13 pivot pin links, and exerts a force downwards at earth brace guard shield annular distance during use, and earth brace guard shield the most upwards opens, and is finished, earth brace
Guard shield annular distance is pushed up power, and guard shield restores.
Expose charged gold utensil to be covered by insulation cover 3, buckle pinning so that it is safer.

Embodiment
Install at electric pole proper height, select the pitch-row of suitable sleeve pipe on cross-arm and corresponding band iron anchor ear by the bar footpath of electric pole,
Horizontal positioned insulator crossarm enters bolt with anchor ear bolt and alternately tightens, and unclamps containing tooth briquetting 11, inserts insulated conductor, is directed at briquetting 10
Arcuate groove, alternately fastening nut coincide to wire with arc groove face, loads insulation cover, buckles pinning.
