INSULATION PIERCING WATERPROOF CONNECTOR EBB AlCu 10-150/1,5-70mm²

MAREL Insulation piercing waterproof connector EBB AlCu 10-150/1,5-70mm² is used to establish electrical contact by simultaneously piercing the insulation on LV ABC conductors of main power distribution line and of network connection insulated conductor. It enables simultaneous installation and connection of surge arrester to both main and tap-off line. It is allowed to use the connector only with a surge arrester.
It is not allowed to use the connector without a surge arrester. MAREL Insulation piercing waterproof connector EBB AlCu 10-150/1,5-70mm² is designed in such a way that it enables connection of LV ABC and branch conductor regardless of whether it is an aluminum or a copper conductor. The elastomer insert eliminates the appearance of electrolytic corrosion since it prevents the appearance of moisture at contact points.
The contact plates are protected with electrical contact grease. When tightening the shear-off nut of MAREL Insulation piercing waterproof connector EBB AlCu 10-150/1,5-70mm² the "teeth" of contact plates penetrate through the insulation and make a perfect contact, thanks to deep penetration into the conductor and large contact surface with it. The contact plates are made of electrolytic sheet of excellent conductivity and very high mechanical strength. Therefore, the penetration through insulation is possible even on very low temperatures.
Tightening of MAREL Insulation piercing waterproof connector EBB AlCu 10-150/1,5-70mm² is done until mechanical damage of shear-off nut occurs. Additional tightening is allowed up to maximum mechanical load, maximum 1.5 circle from the moment of damage of shear-off nut.
Installation under voltage is possible but it is necessary to use adequate protective equipment. MAREL Insulation piercing waterproof connector:

• does not contain parts which could fall off during installation;
• can be used/installed only once;
• has an anti-rotation device (ARD), which enables easy and proper installation because it doesn't allow rotation of upper and lower part of the connector around its axis, which results in easy and deep penetration of contact plates through insulation of LV AВС conductor during installation of the connector;
