Insulated Piercing Connectors
Ιnsulated Piercing Connector is used to achieve contact by simultaneously piercing the insulation on LV ABC conductors of main power distribution line and on insulated copper or aluminιum conductors of network connection lines. Our products are made in such a way that it enables jointing of LV ABC and network connection conductor regardless of whether it is aluminium or copper conductor. Elastomer insert eliminates bimetallic corrosion since it prevents appearance of moisture on contact points. The contacts are protected with electrical contact grease.
When shear head nut is tightened the teeth of contact plates pierce the insulation of LV ABC and achieve excellent contact thanks to deep breakthrough into the conductor and large contact area. Contact plates are made of electrolytic metal sheet of excellent conductivity and very high tensile strength so that piercing of the insulation is possible even at very low temperatures.
Tightening is done until mechanical damage of shear head nut. Additional tightening is allowed until maximum mechanical load, maximum 1,5 circle from the moment of damage of shear head nut. Installation under voltage is possible but proper protective equipment must be used.
