1.1 Piercing connector, simple installation, need not strip the cable coat. 
1.2 Moment nut, piercing pressure is constant, keep good electrìc connection and make no damage to lead 
1.3 Self-seam frame,wetproof, waterproof,and anti-corrosion, extend the using life of insulated lead and connector 
1.4 Adopted special connectìng tablet, apply to joint of Cu(Al) and Cu(Al) or Cu and Al 
1.5 Small electric connecting resistance, connecting resistance less than 1.1 tìmes of the resistance of branch conductor wìth the same length
1.6 Special insulated case body, resistance to illuminatìon and environmental aging, the insulation strength can up to 12KV 
1. 7 Arc surface design,apply to connection with the same(different) diameter, wide connection scope(0.75mm2-400mm2)
