1.Piercing connector, simple installation, need not strip the cable coat.
2.Moment nut, piercing pressure is constant, keep good electric connection and make no damage to lead.
3.Self - seam frame, wet proof,  waterproof, and anti-corrosion, extend the using life of insulated lead and connector. 4.Because body of insulation piercing connectors  and  packing is  respectively made from special eng-ineering plastic and silicon
rubber, so it can work normally under the low temperature -40℃ ~＋105℃ and do not aging.  
5.Small electric connecting resistance, impulse current can be up to 15KA.
6.Special insulated case body,  resistance to illumination and environmental aging, the insulation strength can up to 6kV.
Arc surface design,  apply to connection with the same(different)diameter, wide connection scope(1.5mm2-400mm2).Adopted special connecting tablet, apply to joint of  Cu(AI) and Cu(AI) or Cu and AI.
