Insulated Piercing Connectors

MAREL Insulated 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 aluminum conductors of network connection lines. MAREL Insulated Piercing Connector is made in such a way that it enables jointing of LV ABC and network connection conductor regardless of whether it is aluminum 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 of MAREL Insulated Piercing Connector 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 of MAREL Insulated Piercing Connector 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.
MAREL I.P.C is designed in such a way that fast, easy and reliable installation is possible regardless of the outside temperature. The housing is made of Polyamide PA 6,6 (reinforced with 30-50% glass fibers). resistant to UV radiation, weather conditions, temperature oscillations, aging.
MAREL I.P.C
- does not contain parts which can fall off;
- can be used - installed only once;
- has anti rotation device - ARD, which enables easy and proper installation because it does not allow rotation of the upper and the lower part of the connector around its axis, which results in easy and deep breakthrough of contact plates into the insulation of LV ABC during installation.
The most important norms that MAREL Insulated Piercing Connector fulfills:
· Testing of installation at low temperature
-9°C to -13°C and tightening at 0.7 of tensile force;
· Check of mechanical effect of contact plates on the firmness of main insulated conductor and mechanical stability of tap-off insulated conductor;
· Check of mechanical force limiter - shear head nut, timely contact establishment (0,7 of minimum tensile force) and mechanical durability of the connector (1,5 of Maximum tensile force);
· Testing of dielectric strength by immersing the connector into the water for the period of 30 minutes under voltage of 6 kV;
· Testing of environmental effects, corrosion test, electrical aging test;
· Check of indelibility of marks;
