INSULATION PIERCING CONNECTOR RBB AlCu 10-150mm²

MAREL Insulation Piercing Connector RBB AlCu 10-150mm² is used to install a surge arrester directly onto insulated LV power distribution network. It is allowed to use the connector only with a surge arrester. It is not allowed to use the connector without a surge arrester.
The contacts are protected with electrical contact grease. When tightening the shear-off nut of MAREL Insulation piercing connector RBB AlCu 10-150mm² 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 connector RBB AlCu 10-150mm² 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 is designed in such a way that it enables fast, easy and reliable installation regardless of outdoor temperature.
The housing of the connector is made of Polyamide PA 6.6 (30-50% glass fiber reinforced), resistant to UV rays, weather conditions, temperature changes and aging.
MAREL Insulation Piercing 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 ABС.
