Technical scheme of the present invention: this device is drawn screw rod 7, lightning arrester connecting screw rod 8, end cap 9, briquetting 10, formed containing tooth pressure piece 11, tie down screw 12, earth brace 13, earth brace guard shield 14 by insulated glass fibre reinforced plastic crossbar 1, zinc oxide arrester 2, insulation cover 3, glass reinforced plastic sleeve 4, ground connection connecting rod 5, rectangle joint 6, ground connection.
Insulated glass fibre reinforced plastic crossbar 1 is provided with three holes 1.2 and is spirally connected for lightning arrester 2; Being provided with a hole 1.4 is spirally connected for grounding lead rod 7; If four holes 1.3 are for glass reinforced plastic sleeve assembling, four sleeve pipes form two kinds of pitch-rows, can be suitable for the installation of differing heights, and can greatly increase cross-arm installation strength, can locate ground connection connecting rod 5 again; Two end 1.1 places assemblings end caps 9, it 9.1 is muscle, can stop ground connection connecting rod to move backward, and in two end caps, wall energys stop ground connection connecting rod left and right plaies, and this structure is attractive in appearance, safe, reliably.
On ground connection connecting rod 5 contractive pressure fastening four rectangle joints 6 (Figure 14), ground connection connecting rod is arranged on cross-arm inner chamber, and is located by sleeve pipe and end cap, its manufacturing process is simple and easy, easy for installation, compact conformation; Wherein three rectangle joints are spirally connected for lightning arrester, and a rectangle joint is spirally connected for drawing screw rod 7.
Briquetting 10 with containing tooth pressure piece 11, form a penetrating cable clamp, applicable insulated conductor 240m m
2and following plurality of specifications insulated conductor, its ratchet energy insulation-piercing layer obtains energising; Containing tooth pressure piece 11 and earth brace 13, be spirally connected, earth brace guard shield 14 links with earth brace 13 pivot pins, and during use, in the downward application of force of earth brace guard shield annular distance, earth brace guard shield upwards opens, and is finished the earth brace guard shield annular distance thrust that makes progress, guard shield recovery.
Expose charged gold utensil and covered above by insulation cover 3, fastening pinning, makes it safer.
